According to the synthesis method, one-step solvothermal reaction is adopted for direct synthesis of the finished product, synthesis temperature is low, operation is simple, reaction conditions are mild, the raw materials are cheap and easily available, cost is low, yield is high, no subsequent processing is needed, the synthesis method is friendly to the environment, and is suitable for large scale production.

Description

technical field [0001] The invention belongs to the technical field of electrode material surface treatment, in particular to a vanadium-modified Cu 2 Synthesis of S self-supporting electrode materials. Background technique [0002] Nowadays, with the rapid development of the economy, energy problems and environmental pollution problems are becoming more and more serious, and finding clean and sustainable energy is the breakthrough to solve these two problems. As a new generation of green and sustainable energy, people place high hopes on hydrogen energy. Water splitting technology is one of the effective ways to achieve sustainable production of hydrogen. However, the current commonly used water splitting catalysts are still based on noble metal Pt materials, which severely limits the scale and industrialization of water splitting. To solve this problem, people began to seek alternative Pt-based materials based on transition metal-based compounds with high crustal reserves...
