Bringing Porous Framework Materials toward Photocatalytic HO Production.

Photocatalytic HO production driven by renewable solar energy is a promising and sustainable approach, with porous framework materials such as metal-organic frameworks (MOFs), covalent organic frameworks (COFs), and hydrogen-bonded organic frameworks (HOFs) emerging as highly efficient catalysts. This Review first presents the current research state of porous framework materials in HO photosynthesis, focusing on the progress in HO production across different porous frameworks and mechanism insights gained through advanced techniques. Furthermore, a systematic categorization of material modifications aimed at enhancing the photocatalytic efficiency is provided, linking structural modifications to improved HO production performance.

Ultra-small cesium silver bismuth bromide quantum dots fabricated by modified hot-injection method for highly efficient degradation of contaminants in organic solvent.

Lead-free halide perovskite material has drawn fast-growing interest due to its superior solar-conversion efficiency and nontoxic nature. In this work, we have successfully fabricated cesium silver bismuth bromide (CsAgBiBr) quantum dots utilizing the hot injection method. The as-synthesized quantum dots were characterized by combined techniques, which showed remarkable visible-light photocatalytic activity for organic dyes and antibiotic degradation in ethanol.
