Description

technical field

[0001] The invention specifically relates to a method for preparing highly-doped nitrogen-phosphorous carbon nanosheets with high-efficiency hydrogen production, and belongs to the technical field of preparation of new energy materials. Background technique

[0002] To meet the challenge of decreasing fossil fuels, the development of electrochemical renewable energy conversion and storage technologies and related materials is imminent. Although noble metal-based catalysts have excellent performance, their large-scale industrial application cannot be realized due to the low reserves of noble metals and high cost. Carbon material is a material with abundant reserves, wide distribution range, low cost, easy synthesis and many synthesis methods. It is widely favored in many industries because of its excellent performance brought by its unique electronic structure. However, due to the lack of effective catalytic active sites on the surface of carbon materials, t...
