[0002] With the rapid development of global science and technology and the continuous growth of population, people's demand for energy is increasing. However, the fossil fuel resources that people currently rely on are not only limited in quantity, but also the greenhouse gases such as carbon dioxide produced by their combustion exacerbate the problem of global warming. Therefore, it has become a top priority to develop clean and sustainable energy technologies and reduce dependence on fossil fuels. As an important link in the process of hydrogen production by electrolysis of water, the study of oxygen evolution by electrolysis of water is of great significance to promoting the development of the hydrogen energy economy.

[0003] In the process of water electrolysis, oxygen evolution reaction (OER) is a key half-reaction. Its reaction kinetics are relatively slow, the reaction energy barrier is high, and it can only occur at a higher overpotential, which seriously reduces the efficiency of electricity-hydrogen fuel conversion. Therefore, the development of efficient and stable oxygen evolution reaction catalysts is crucial to improve the efficiency of hydrogen production by water electrolysis.

[0004] Currently, the best OER catalysts are iridium oxide and ruthenium oxide, but they are expensive and have poor stability under certain conditions. Therefore, researchers are committed to developing low-cost and efficient transition metal-based OER electrocatalysts, such as cobalt, nickel, and iron. These materials not only have good catalytic performance, but also have high environmental adaptability and long-term stability.
