    Wiley ; 2022

    Abstract: Single‐atom catalysts (SACs) are being pursued as economical electrocatalysts. However, their low active‐site loading, poor interactions, and unclear catalytic mechanism call for significant advances. Herein, atomically dispersed Ni/Co dual sites anchored on nitrogen‐doped carbon (a‐NiCo/NC) hollow prisms are rationally designed and synthesized. Benefiting from the atomically dispersed dual‐metal sites and their synergistic interactions, the obtained a‐NiCo/NC sample exhibits superior electrocatalytic activity and kinetics towards the oxygen evolution reaction. Moreover, density functional theory calculations indicate that the strong synergistic interactions from heteronuclear paired Ni/Co dual sites lead to the optimization of the electronic structure and the reduced reaction energy barrier. This work provides a promising strategy for the synthesis of high‐efficiency atomically dispersed dual‐site SACs in the field of electrochemical energy storage and conversion.

    Atomically Dispersed Fe Sites Regulated by Adjacent Single Co Atoms Anchored on N‐P co‐doped Carbon Structures for Highly Efficient Oxygen Reduction Reaction
    Wiley ; 2023
    In:  Advanced Materials
    Details
    In: Advanced Materials, Wiley
    Abstract: Manipulating the coordination environment and electron distribution for heterogeneous catalysts at the atomic level is an effective strategy to improve the electrocatalytic performance but remains challenging. Herein, atomically dispersed Fe and Co anchored on nitrogen, phosphorus co‐doped carbon hollow nanorod structures (FeCo‐NPC) are rationally designed and synthesized. The as‐prepared FeCo‐NPC catalyst exhibits significantly boosted electrocatalytic kinetics and greatly upshifted half‐wave potential for the oxygen reduction reaction. Furthermore, when utilized as the cathode, the FeCo‐NPC catalyst also displays excellent zinc‐air battery performance. Experimental and theoretical results demonstrate that the introduction of single Co atoms with Co‐N/P coordination around isolated Fe atoms induces asymmetric electron distribution, resulting in the suitable adsorption/desorption ability for oxygen intermediates and the optimized reaction barrier, thereby improving the electrocatalytic activity.

    Zincophilic Interfacial Manipulation against Dendrite Growth and Side Reactions for Stable Zn Metal Anodes
    Wiley ; 2023
    In:  Angewandte Chemie
    Details
    In: Angewandte Chemie, Wiley
    Abstract: Constructing multifunctional interphases to suppress the rampant Zn dendrite growth and detrimental side reactions is crucial for Zn anodes. Herein, a phytic acid (PA)‐ZnAl coordination compound is demonstrated as a versatile interphase layer to stabilize Zn anodes. The zincophilic PA‐ZnAl layer can manipulate Zn 2+ flux and promote rapid desolvation kinetics, ensuring the uniform Zn deposition with dendrite‐free morphology. Moreover, the robust PA‐ZnAl protective layer can effectively inhibit the hydrogen evolution reaction and formation of byproducts, further contributing to the reversible Zn plating/stripping with high Coulombic efficiency. As a result, the Zn@PA‐ZnAl electrode shows a lower Zn nucleation overpotential and higher Zn 2+ transference number compared with bare Zn. The Zn@PA‐ZnAl symmetric cell exhibits a prolonged lifespan of 650 h tested at 5 mA cm −2 and 5 mAh cm −2 . Furthermore, the assembled Zn battery full cell based on this Zn@PA‐ZnAl anode also delivers decent cycling stability even under harsh conditions.

    Wiley ; 2021

    Abstract: Mn‐based oxides have sparked extensive scientific interest for aqueous Zn‐ion batteries due to the rich abundance, plentiful oxidation states, and high output voltage. However, the further development of Mn‐based oxides is severely hindered by the rapid capacity decay during cycling. Herein, a two‐step metal–organic framework (MOF)‐engaged templating strategy has been developed to rationally synthesize heterostructured Mn 2 O 3 –ZnMn 2 O 4 hollow octahedrons (MO–ZMO HOs) for stable zinc ion storage. The distinctive composition and hollow heterostructure endow MO–ZMO HOs with abundant active sites, enhanced electric conductivity, and superior structural stability. By virtue of these advantages, the MO–ZMO HOs electrode shows high reversible capacity, impressive rate performance, and outstanding electrochemical stability. Furthermore, ex situ characterizations reveal that the charge storage of MO–ZMO HOs mainly originates from the highly reversible Zn 2+ insertion/extraction reactions.

    Bimetal‐Organic Framework Nanoboxes Enable Accelerated Redox Kinetics and Polysulfide Trapping for Lithium‐Sulfur Batteries

    In: Angewandte Chemie, Wiley, Vol. 135, No. 31 ( 2023-08)
    Abstract: Lithium‐sulfur (Li−S) batteries are considered as promising candidates for next‐generation energy storage systems in view of the high theoretical energy density and low cost of sulfur resources. The suppression of polysulfide diffusion and promotion of redox kinetics are the main challenges for Li−S batteries. Herein, we design and prepare a novel type of ZnCo‐based bimetallic metal–organic framework nanoboxes (ZnCo‐MOF NBs) to serve as a functional sulfur host for Li−S batteries. The hollow architecture of ZnCo‐MOF NBs can ensure fast charge transfer, improved sulfur utilization, and effective confinement of lithium polysulfides (LiPSs). The atomically dispersed Co−O 4 sites in ZnCo‐MOF NBs can firmly capture LiPSs and electrocatalytically accelerate their conversion kinetics. Benefiting from the multiple structural advantages, the ZnCo‐MOF/S cathode shows high reversible capacity, impressive rate capability, and prolonged cycling performance for 300 cycles.

    Superhydrophobic and Conductive Wire Membrane for Enhanced CO 2 Electroreduction to Multicarbon Products
    Wiley ; 2023

    Abstract: Gas‐liquid‐solid triple‐phase interfaces (TPI) are essential for promoting electrochemical CO 2 reduction, but it remains challenging to maximize their efficiency while integrating other desirable properties conducive to electrocatalysis. Herein, we report the elaborate design and fabrication of a superhydrophobic, conductive, and hierarchical wire membrane in which core–shell CuO nanospheres, carbon nanotubes (CNT), and polytetrafluoroethylene (PTFE) are integrated into a wire structure (designated as CuO/F/C(w); F, PTFE; C, CNT; w, wire) to maximize their respective functions. The realized architecture allows almost all CuO nanospheres to be exposed with effective TPI and good contact to conductive CNT, thus increasing the local CO 2 concentration on the CuO surface and enabling fast electron/mass transfer. As a result, the CuO/F/C(w) membrane attains a Faradaic efficiency of 56.8 % and a partial current density of 68.9 mA cm −2 for multicarbon products at −1.4 V (versus the reversible hydrogen electrode) in the H‐type cell, far exceeding 10.1 % and 13.4 mA cm −2 for bare CuO.
