Highly stable and durable ZnInS nanosheets wrapped oxygen deficient blue TiO(B) catalyst for selective CO photoreduction into CO and CH.

Developing new and highly stable efficient photocatalysts is crucial for achieving high performance and selective photocatalytic CO conversion. In this paper, we designed a one-dimensional oxygen-deficient blue TiO(B) (BT) catalyst for improved electron mobility and visible light accessibility. In addition, hexagonal ZnInS (ZIS) nanosheets with a low bandgap and great visible light accessibility are employed to produce effective heterostructures with BT.

Synthesis of Pore-Wall-Modified Stable COF/TiO Heterostructures via Site-Specific Nucleation for an Enhanced Photoreduction of Carbon Dioxide.

Constructing stable heterostructures with appropriate active site architectures in covalent organic frameworks (COFs) can improve the active site accessibility and facilitate charge transfer, thereby increasing the catalytic efficiency. Herein, a pore-wall modification strategy is proposed to achieve regularly arranged TiO nanodots (≈1.82 nm) in the pores of COFs via site-specific nucleation.
