Embedding CsPbBr Quantum Dots into an InO Nanotube for Selective Photocatalytic CO Reduction to Hydrocarbon Fuels.

Halide perovskite quantum dots (QDs) are one of the most prospective candidates for photocatalytic CO reduction, but their photocatalytic performances are far from satisfactory due to structural instability and severe charge recombination. In this study, we demonstrated a CsPbBr QDs/InO hierarchical nanotube (CPB/IO) for efficient CO conversion, in which CsPbBr QDs were well-dispersed on the In-MOF-derived InO nanotube by a facile self-assembly process. The optimized CPB/IO catalyst displayed an enhanced photocatalytic CO performance with a (CO + CH) generation rate of 16.

Carbon Dots as an Electron Acceptor in the ZnInS@MIL-88A Heterojunction for Enhanced Visible-Light-Driven Photocatalytic Hydrogen Evolution.

In this study, visible-light-responsive carbon dots (CDs)/ZnInS@MIL-88A (C/ZI@ML) photocatalysts were successfully prepared through loading CDs and ZnInS nanosheets on MIL-88A(Fe) to form a ternary heterojunction. The detailed characterization indicated that the two-dimensional ZnInS nanosheets were uniformly coated on the surface of MIL-88A(Fe), and ZnInS/MIL-88A(Fe) exhibited enhanced photocatalytic hydrogen production performance (1259.63 μmol h g) compared to that of pristine MIL-88A(Fe) and ZnInS under visible light illumination.
