Understanding the variations in degradation pathways and generated by-products of antibiotics in modified TiO and ZnO photodegradation systems: A comprehensive review.

This review examines various modification techniques, including metal doping, non-metal doping, multi doping, mixed doping, and the construction of heterojunction photocatalysts, for enhancing the performance of pure TiO and ZnO in the photodegradation of antibiotics. The study finds that mixed and multi doping approaches are more effective in improving photodegradation performance compared to single doping. Furthermore, the selection of suitable semiconductors for constructing heterojunction photocatalysts is crucial for achieving an efficient charge carrier separation.

One-Pot Synthesis of 2D-2D WO /g-C N Photocatalyst in Reverse Microemulsion System via Supercritical CO for Enhanced Hydrogen Generation.

Construction of Z-scheme photocatalyst is an effective approach for using solar energy to produce hydrogen during water splitting. Herein, 2D/2D WO /g-C N heterojunction photocatalyst was synthesized by a convenient and green method including exfoliation and heterojunction procedures, in the reverse microemulsion system via supercritical carbon dioxide (scCO ). The resultant W/CN-10.

A Facile Route to Synthesis of Hierarchically Porous Carbon Micelle System for Bifunctional Electrochemical Application.

Well-ordered hierarchically porous carbon (HPC) nanomaterials have been successfully synthesized by a facile, efficient, and fast heated-evaporation induced self-assembly (HISA) method. A micelle system was employed as the template by using the HISA method for the first time, which possessed great potential in the large-scale production of HPC materials. Various surfactants, including triblock copolymer Pluronic F127, P123, F108, and cationic CTAB, were used in the polymerization process as templates to reveal the relationship between the structure of surfactants and architecture of the as-prepared HPCs.

Synthesis of Atomically Thin g-CN Nanosheets via Supercritical CO Doping with Single-Atom Cobalt for Photocatalytic Hydrogen Evolution.

The atomically thin nanosheets of graphitic carbon nitride (g-CN) with mesopores have been successfully exfoliated with supercritical CO (scCO). The thickness of the as-synthesized samples could be directly tailored by simply regulating the scCO pressure. The obtained bilayer mesoporous g-CN nanosheets doped with monatomic Co through a microwave-assisted approach havve been employed as single-atom catalysts to enhance the photocatalytic hydrogen evolution performance.
