Description

Technical Field

[0001] The utility model belongs to the technical field of production of catalysts for hydrogen production by electrolysis of water, and specifically relates to a production system of platinum-loaded cobalt-nitrogen-carbon carrier catalysts for hydrogen production by electrolysis of water. Background Art

[0002] At present, the main source of hydrogen is industrial fossil fuels, including methane reforming, alcohol cracking, and coal gasification, which will cause harm to the environment again. The products of water electrolysis hydrogen production are hydrogen and oxygen, which are completely green and pollution-free. It is a truly clean and sustainable energy conversion technology. Although the technology of water electrolysis hydrogen production is mature, due to the high electricity price and low hydrogen production efficiency, it is difficult to achieve large-scale promotion of water electrolysis hydrogen production in industry. Therefore, how to reduce the energy consumption of water electrolysis and improve the energy conversion efficiency is an urgent problem to be solved in water electrolysis hydrogen production technology.

[0003] Electrocatalysts are the key to hydrogen production by water electrolysis. The use of suitable electrocatalysts can significantly reduce the overpotential of the hydrogen evolution reaction and promote the hydrogen evolution reaction, which plays an important role in reducing energy consumption and improving energy conversion efficiency. Platinum-based catalysts have always been considered as the benchmark electrocatalysts for hydrogen production by water electrolysis. However, their high price and low abundance limit their large-scale application. Therefore, developing electrocatalysts with higher catalytic activity and more economic benefits, reducing the overpotential of water electrolysis, and improving energy conversion efficiency are the key to reducing the energy consumption of hydrogen production by water electrolysis, and are also the bottleneck restricting the development of the hydrogen production industry by water electrolysis.
