Bifunctional Polyoxometalate-Carbon Foam Composite: Photocatalytic Degradation of Organic Pollutants and Synergistic Photosynthesis of High-Value-Added Chemical Fuels.

Polyoxometalates (POMs) have attracted much attention in photocatalytic degradation of organic pollutants due to their environmental friendliness, high catalytic activity, and abundant redox sites from their unique structures. However, their practical use in liquid-solid photocatalytic systems is restricted by issues like low specific surface area, agglomeration tendency, and high water solubility. To address these problems, we used polyurethane foam (a common solid waste) as a template and phenolic resin as a carbon source to synthesize a highly porous carbon foam.

Periodic Frustrated Lewis Pairs on Bimetallic Oxide Semiconductors for CO Adsorption and Photocatalytic Conversion.

Lewis acids (LAs) or Lewis bases (LBs) have been recognized as crucial catalytically active sites for enhancing the adsorption and conversion of inert CO. However, engineering of periodic frustrated Lewis pairs (PFLPs) on the surfaces of semiconductor photocatalysts presents significant challenges, and the synergistic mechanism of PFLPs in CO photoreduction remains unclear. In this study, we propose a strategy that utilizes periodic oxygen vacancies to engineer dual-metallic PFLPs on bimetallic oxide semiconductor surfaces.
