Description
Summary:The oxygen evolution reaction (OER), as an essential process in water decomposition and air batteries, has received increasing attention in the context of clean energy production and efficient energy storage. With their abundant composition and morphology, manganese-based oxides (MnO x ) offer great possibilities for the exploration and design of OER catalysts. In this paper, three classes of MnO x materials, including MnO 2 , Mn 2 O 3, and Mn 3 O 4 , are systematically reviewed and their development and applications in OER systems are comprehensively presented. Subsequently, the effects of Jahn-Teller distortion and the question of the active site and stability of MnO x in the OER are discussed, and the presence of Mn 3+ , which is considered essential for OER activity, and strategies for improving performance are proposed. This paper focuses on the impact of crystal structure, catalytic mechanisms, and design strategies on MnO x . The oxygen evolution reaction (OER), as an essential process in water decomposition and air batteries, has received increasing attention in the context of clean energy production and efficient energy storage.
