How It Compares
Within the oxide oxygen-evolution catalysts class.
Unlike the layered lithium-based oxides such as LiCoO2 or LiNiO2 which are primarily optimized for battery cathode performance, MnWO4 functions as a distinct catalytic material. While perovskite-structured oxides like LaMnO3 are widely recognized for their surface reactivity, MnWO4 offers a different structural framework that provides unique active sites for oxygen evolution, distinguishing it from the more common spinel or perovskite members of this catalyst class.
