Phase & Morphology Engineered Surface Reducibility of MnO2 Nano-heterostructures: Implications on Catalytic Activity Towards CO Oxidation

This work addresses two vital aspects of catalytic nanohybrids viz., a chemistry-based control of crystallographic phase/ morphology that serves as a handle for engineering the surface reducibility and correlating the catalytic activity to the reducibility. We would like to emphasize that the material addressed in this paper is an earth-abundant oxide MnO₂, much favorable for practical applications in terms of cost and availability.
