Recent Developments in Manganese‑Based Materials for Acidic Oxygen Evolution Catalysis
https://doi.org/10.1007/s11814-025-00512-2
Abstract
Water electrolysis is gaining attention as a method for clean hydrogen production, making the development of efficient acidic
oxygen evolution reaction (OER) catalysts crucial. MnO2,
with its diverse crystalline phases, has emerged as a promising
candidate due to its stability and catalytic activity under acidic conditions. This review explores MnO2-
based catalysts,
focusing on the role of crystal structure, morphology, valence states, and defect engineering in enhancing performance. The
reaction mechanisms of OER, along with the transformation pathways of MnO2
during the reaction, are examined to provide
a deeper understanding of its catalytic behavior. Furthermore, based on these fundamental insights, recent advancements
in MnO2-
based catalysts are reviewed, categorizing them into unsupported catalysts and MnO2
as a support material, with
discussions on noble- and non-noble-metal incorporation strategies for optimizing their practical application in acidic OER.
