Decoupling the Impacts of Engineering Defects and Band Gap Alignment Mechanism on the Catalytic Performance of Holey 2D CeO_2−x‐Based Heterojunctions

Critical catalysis studies often lack elucidation of the mechanistic role of defect equilibria in solid solubility and charge compensation. This approach is applied to interpret the physicochemical properties and catalytic performance of a free‐standing 2D–3D CeO 2− x scaffold, which is comprised of holey 2D nanosheets, and its heterojunctions with MoO 3− x and RuO 2 . The band gap alignment and structural defects are engineered using density...
