Carbon quantum dots modified TiO2 composites for hydrogen production and selective glucose photoreforming

Heng Zhao et al.

Summary: This study demonstrates an improved selectivity in glucose photoreforming for coproduction of hydrogen and arabinose under neutral conditions using carbon quantum dots (CQDs) modified TiO2 composites. The colored CQDs in the composites enhance the glucose to arabinose conversion selectivity and efficient hydrogen evolution in water. The work not only offers new insights into CQDs-assisted biomass valorization and hydrogen coproduction, but also suggests a potential application for solar energy utilization in a noble-metal-free system.

A metal-free photocatalyst for highly efficient hydrogen peroxide photoproduction in real seawater

Qingyao Wu et al.

Summary: Artificial photosynthesis of H2O2 from water and oxygen has attracted widespread interest, but most photocatalysts face salt-deactivation effects. In this study, a metal-free photocatalyst based on carbon dots was synthesized for H2O2 photoproduction in seawater, showing a significantly higher yield compared to pure polymers. In-depth analysis revealed the active sites and catalytic mechanism of this composite catalyst in seawater, providing a highly efficient and practical catalyst for H2O2 photoproduction.

Preparation of ordered mesoporous F-H2Ti3O7 nanosheets using orthorhombic HTiOF3 as a precursor and their highly efficient degradation of tetracycline hydrochloride under simulated sunlight

Chentao Hou et al.

Summary: The study discussed the transformation relationship between HTiOF3 and TiOF2 under hydrothermal conditions, as well as the effects of alkaline hydrothermal treatment and ion-exchange treatment on their phase and morphology. It was confirmed that hexagonal HTiOF3 can serve as a precursor for preparing F-H2Ti3O7 nanosheets with ordered mesoporous structure. The prepared F-H2Ti3O7 nanosheets showed high specific surface area and macroporous volume, and exhibited efficient degradation of tetracycline hydrochloride through photocatalytic processes.
