Abstract:: Alkaline electrolysis of water is one of the cleanest and most efficient processes to produce hydrogen. The electrolysis process consists of hydrogen evolution reaction and oxygen evolution reaction. The oxygen evolution reaction (OER) is a four-electron involved step, determining the kinetics and the energy conversion efficiency. Non-noble metal oxides benefit from the abundant resource, low cost and good catalytic activity. They exhibit great potential as the electrode coatings in OER with wide attention around the world. In this paper, the attention was focused on the different types of non-noble metal oxides as the active OER electrodes, including monometal oxides, multi-metal oxides and high-entropy oxides. Besides, the current optimization strategies for the non-noble metal oxide based OER electrodes were summarized as well. In addition, this review also introduces several common fabrication techniques for the non-noble metal oxide OER electrodes. Finally, based on the analyses of the recent investigation of the non-noble metal oxide OER electrodes, we proposed some suggestions and outlooks for their future development.
