The successive ionic layer adsorption and reaction (SILAR) method was used to deposit several CdSe quantum dots (QDs) on the surface of g-C3N4 nanosheets. In comparison single moiety g-C3N4, as-prepared heterostructures displayed an improved bifunctional photo- electrocatalytic activity for oxygen (OER) hydrogen evolution reactions (HER). Significantly, 30 SILAR cycles optimized QDs/g-C3N4 heterostructure exhibited high performances stabilities OER HER in alkaline conditions. catalyst also efficient photocatalytic toward H2 produced 4306 μmol gas with 23.8% apparent yield presence triethanolamine as a sacrificial agent.

Published: July 24, 2022

The existence of antibiotics in the environment can trigger a number issues by fostering widespread development antimicrobial resistance. Currently, most popular techniques for removing antibiotic pollutants from water include physical adsorption, flocculation, and chemical oxidation, however, these processes usually leave significant quantity reagents polymer electrolytes water, which lead to difficulty post-treating unmanageable deposits. Furthermore, though cost-effectiveness, efficiency, reaction conditions, nontoxicity during degradation are hurdles overcome, variety photocatalysts be used degrade pollutant residuals, allowing potential solutions issues. Thus, urgent need effective rapid photocatalytic leads an increased interest finding more sustainable catalysts degradation.
