Abstract:: Alkaline water electrolysis is one of the cleanest and most efficient processes to produce hydrogen. The electrolysis process consists of hydrogen evolution reaction (HER) and oxygen evolution reaction (OER). The OER is a fourelectron involved process characterized by sluggish kinetics and low energy conversion efficiency, serving as the bottleneck in water electrolysis for hydrogen production. Therefore, electrocatalysts are often required to enhance the reaction efficiency. Non-noble metal oxides benefit from the abundant resource, low cost and good catalytic activity, exhibiting great potential to drive and catalyze the OER and attracting worldwide attention. In this paper,according to the different types of non-noble metal oxides, including monometal oxides, multi-metal oxides and high-entropy oxides, the research progress of the non-noble metal oxide OER electrodes was reviewed. Besides, the current performance optimization strategies for the non-noble metal oxide based OER electrodes were summarized. In addition, this review also introduced several common fabrication techniques for the non-noble metal oxide OER electrodes. Finally, based on the analysis of the recent investigation of the non-noble metal oxide OER electrodes, we proposed some suggestion and outlook for their future development.
