    Abstract: Uninterrupted H 2 production from water electrolysis powered by sunlight is critical for the development of hydrogen economy. The key to realize this purpose is to construct integrated devices involving energy storage and water splitting and corresponding efficient electrocatalysts, which remains a significant challenge. Herein, we developed a new type of solar hydrogen production integrated device using rechargeable zinc–air battery as energy storage media and energy driven device and alkaline water electrolyzer as the H 2 production terminal, wherein highly active FeNi phosphide-carbon hybrid materials prepared from the organophosphonic acid modified polyaniline polymer were employed as advanced electrode catalysts for the trifunctional HER/OER/ORR to improve device efficiency. Density functional theory calculations demonstrate that the hetero-engineering between FeNi phosphide and carbon modulates the d-band center, thereby improving the adsorption of intermediates during reactions. Further, the fabricated zinc–air battery with metal phosphide-based catalyst as an air cathode displays large power density (117 mW cm −2 ), excellent charge–discharge capability (voltage gap of 0.74 V at 10 mA cm −2 ), and outstanding cycling stability (over 500 h). The assembled water splitting electrolyzer also delivers low overpotentials (1.67 V at 20 mA cm −2 ) and excellent stability. Furthermore, two zinc–air batteries in series powered the overall water-splitting cell achievingan average H 2 production rate of 0.24 mL min −1 , demonstrating significant prospects for H 2 production. Ultimately, this integrated water electrolysis device exhibited excellent stability in 15 day tests with the commercial silicon photovoltaic cell as the power source by day and the rechargeable zinc–air batteries provide electricity at night, without any decay in the performance. This work may provide new opportunities for low-cost and uninterruptible solar hydrogen production by constructing integrated devices.

    Abstract: Conjugated organic polymers have been deemed as one type of the most promising electrode materials for lithium-ion batteries (LIBs) due to their structural diversity and functional designability. However, the poor conductivities and limited redox-active sites of these polymers severely impede their applications in LIBs. Herein, four novel pyrene-4,5,9,10-tetraone (PTO)-based polymers (namely PTO-Bz, PTO-Py, PTO-Pm, and PTO-Tz) were designed and synthesized as cathode materials with high electrochemical activity (four redox sites of PTO units) and superb structural/chemical stability. By changing the N content in aryl linkers, the electronic conduction and transportation of polymer structures could be readily adjusted, leading to enhanced electrochemical activity. As a result, the optimal PTO-Py polymer displays high electronic conductivity and enhanced pseudocapacitive behavior compared with the other samples. When evaluated as a cathode for LIBs, the PTO-Py electrode shows a high lithium storage performance of 220.4 mA h g −1 with an ICE of 97.0% at 0.1 A g −1 , superior rate performance (153.1 mA h g −1 at 10 A g −1 ), and excellent cycling abilities (70.8% capacity retention over 2000 cycles at 1.0 A g −1 ). In addition, ex situ FT-IR and XPS analyses were also carried out to further understand the Li + storage mechanism. This work unveils an efficacious strategy to exploit high-performance conjugated organic polymer electrodes for energy storage systems.

    Abstract: The imperative for cost-effective catalysts governing the hydrogen oxidation reaction (HOR) remains pivotal for advancing the commercial viability of alkaline H 2 –O 2 fuel cells. High entropy alloys (HEAs) represent an exceptionally promising class of candidates due to their capacity to provide a multifaceted parameter space for optimizing electronic structures and catalytic sites. In this study, we employed the polymer-assisted pyrolysis method to synthesize FeCoNiMoW HEA nanoparticles (NPs) enveloped within a porous carbon skeleton. Such FeCoNiMoW NPs exhibit high entropy characteristics, subtle lattice distortions, and a modulated electronic structure, resulting in a discernibly enhanced HOR performance characterized by larger exchange/kinetics current densities and superior antioxidation ability compared to their pure Ni-based counterparts in alkaline media. Density functional theory (DFT) calculations elucidate the electronic structures of the FeCoNiMoW active sites, revealing robust d–d electron interactions within the constituent metals. The presence of multi-active sites with optimized adsorption energy for intermediates is also identified, thereby mitigating the Gibbs free energy barrier in the HOR process. This comprehensive investigation not only affords intricate insights into the complex structural attributes and catalytic mechanisms inherent in multielement HEA systems but also serves as a foundation for the informed design of highly efficient catalysts featuring d–d orbital interactions in hydrogen electrolysis, and beyond.

    Abstract: The electrocatalytic splitting of water holds great promise as a sustainable and environmentally friendly technology for hydrogen production. However, the sluggish kinetics of the oxygen evolution reaction (OER) at the anode significantly hampers the efficiency of this process. In this comprehensive perspective, we outline recent advancements in innovative strategies aimed at improving the energy and economic efficiency of conventional water electrolysis, thereby facilitating efficient hydrogen generation. These novel strategies mainly include: (i) sacrificial-agent-assisted water electrolysis, which integrates thermodynamically favorable small molecules to replace the OER while simultaneously degrading pollutants; (ii) organic upgrading-assisted water electrolysis, wherein thermodynamically and kinetically favorable organic oxidation reactions replace the OER, leading to the production of high-value chemicals alongside hydrogen; (iii) self-powered electrolysis systems, achieved by coupling water splitting with metal-based batteries or fuel cells, enabling hydrogen production without the need for additional electricity input; and (iv) self-catalyzed electrolysis systems driven by the spontaneous metal oxidation at the anode, which provides electrons for hydrogen evolution at the cathode. In particular, we emphasize the design of electrocatalysts using non-noble metal elements, elucidate the underlying reaction mechanisms, and explore the construction of efficient electrolyzers. Additionally, we discuss the prevailing challenges and future prospects, aiming to foster the development of electrocatalytic systems for highly efficient hydrogen production from water in the future.

    Abstract: Photocatalytic, photoelectrochemical and electrocatalytic water splitting provide advanced approaches to produce green hydrogen as a sustainable and renewable energy carrier. The development of highly efficient catalysts is the key to achieving cost-effective and large-scale production of hydrogen. Recently, P-containing catalysts have gained a great deal of attention owing to their diverse chemical valence states, tunable structure and unique physicochemical properties. In this review, an overview of up-to-date progress in water splitting of P-containing photo- and electro-catalysts including elemental P, transition metal phosphides, metal phosphates/phosphonates and metal phosphorus trichalcogenides is provided. A general introduction to the water splitting mechanism and the activity origin of P-containing catalysts is briefly presented to provide rational guidance for the design of highly efficient catalysts. Notably, innovational strategies to design P-containing catalysts with enhanced catalytic activity are summarized with respect to modifying the phase, introducing foreign elements, tailoring morphology and engineering interfaces. In each section, we aim to deeply clarify the theory–structure–property relationship and provide underlying reasons behind enhanced catalytic performance. Finally, some challenges and research orientations of P-containing catalysts toward water splitting are briefly proposed from the perspectives of practical application and mechanism investigation.

    Abstract: The burgeoning field of anion-exchange membrane fuel cells (AEMFCs) presents a promising avenue to circumvent the reliance on scarce and costly Pt-based catalysts, offering a zero-carbon emission alternative. Despite the success of numerous noble metal-free cathodic oxygen reduction reaction catalysts in AEMFCs, the sluggish kinetics of the anodic hydrogen oxidation reaction (HOR) in alkaline media, necessitating a high Pt amount, poses a substantial impediment to AEMFC development. This review delves into the intricate landscape of the alkaline HOR, commencing with exploration of prevailing theories grounded in diverse activity descriptors, such as the hydrogen binding energy theory and bifunctional theory. The elucidation of sluggish kinetics and reaction mechanisms in alkaline electrolytes serves as the foundation for the analysis of noble and non-noble metal catalysts, encompassing considerations of morphology, composition, local structure, heterostructure, spillover effects, single atomic catalysts, and oxyphilic site engineering. Emphasis is placed on addressing pivotal but often overlooked challenges, including long-term stability, antioxidation ability, and CO tolerance of HOR catalysts. This review underscores the significance of theoretical investigations and in situ characterization technologies. Subsequently, recent strides in AEMFCs, leveraging various electrocatalysts for enhanced activity and durability, are meticulously summarized. The narrative concludes by spotlighting persisting controversies surrounding alkaline HOR mechanisms, along with an exposition of challenges and prospective research directions vital for the eventual commercialization of AEMFCs.
