| Abstract: | With the increasing demand for sustainable energy, human beings put forward higher requirements for the preparation of clean energy. Electrocatalytic water splitting has become a promising way to solve the energy crisis because of the characteristics of high efficiency and cleanliness. The catalyst of oxygen evolution reaction (OER), an important part of electrocatalytic water splitting, plays a critical role in water splitting. Transition metals (TMs) are generally used as active sites to realize high-efficiency electrocatalytic in the water. To better understand the role of TMs in the OER catalysts. This review focused on the relationship between TMs and OER catalyst activity. The mechanism of synthesis strategy in different types of TMs-based catalysts was also summarized. The challenges and prospects of developing economic and efficient TMs-based OER catalysts were discussed. |
