The rise of manganese as catalysts for acidic water oxidation: A mini review
Zhaozhao Wang, Licheng Lu
Abstract
The oxidation of water is quite popular and essential in practical applications for human beings. MnOx as electrocatalysts has the merits of robust durability and activity even in acidic mediums. Reaction mechanisms for OER on MnOx in acid are summarized at an atomic level. The influences of the crystal facets of MnOx on OER in acidic mediums are discussed theoretically and experimentally. Moreover, practical applications of pure MnOx in PEM-based water electrolysis are put forward and highlighted. Various Mn-based heterogeneous catalysts with earth-abundant or noble metals incorporation are reviewed. This study offers several strategies to enhance the activity and durability of the MnOx based electrocatalysts.
