Abstract:
Metal and metal oxides are extremely competitive in various applications such as catalysis and energy storage, while the intrinsically unsatisfactory ion/electron conductivity and/or large volume swing severely inhibit their inherent potentials. Quantum dots (QDs) can significantly promote the conductivity, buffer volume variation, and introduce novel physical/chemical properties, especially in cooperation with mesoporous carbon (MC), and hence are attracting ever‐increasing attention. However, it is still a worldwide challenge to exploit a facile, efficient, environmentally benign, commercially applicable, and, in particular, universal method for varied QDs/MC hybrids. In this work, a powerful approach is proposed on basis of corn straw piths, and a synthetic mechanism is proposed and investigated systematically. According to this route, Ni, Co, Cu, and MnO QDs/MC nanoplates are successfully fabricated. As a typical example, ultrasmall Ni QDs (5–7 nm) are homogeneously distributed on the large surface of MC nanoplates and exhibit a reversible capacitance of 2420 F g −1 at 500 mA g −1 and rate performance. This work discloses a new and paramount path to exploit versatile QDs/MC hybrids for promising applications such as lithium ion batteries, solar cells, Li–air batteries, and other promising fields with electrochemical catalysts.
