Micro/nanomaterials with multilayer core-shell structures are receiving widespread attentions due to their potential in energy storage and conversion systems. However, simple fabrication of multilayered core-shell structured micro/nanomaterials with the consistent...

Heterostructured Cu/CuO Nanoparticles Embedded within N-Doped Carbon Nanosheets for Efficient Oxygen Reduction Reaction

“…Among them, metal-air cells and fuel cells have received widespread attention due to their low cost, high efficiency, and clean and pollution-free characteristics. Electrochemical oxygen reduction reaction (ORR) is the core step of their reactions and, due to the slow reaction kinetics, is also the main cause of their voltage loss [11][12][13], so it is of great significance to seek stable and efficient catalytic electrodes for improving the oxygen reduction reaction. It is well known that platinum-based materials exhibit good catalytic activity for ORR, but there are problems, such as low abundance, high price and stability in alkaline solutions, and poor methanol tolerance, which greatly hinder its wide application.…”
