Abstract

It is well known that the resource utilization of renewable biomass waste is one of the feasible strategies to reduce environmental pollutants. In this study, a novel composite photocatalyst (g-C₃N₄@CaCO₃) was successfully designed and synthesized using a simple calcination method. The precursors of the composite were mainly melamine and waste eggshells. The prepared g-C₃N₄@CaCO₃ composite catalyst showed excellent photocatalytic degradation activity for methylene blue (MB) in wastewater. Compared with pure g-C₃N₄, the g-C₃N₄@CaCO₃ composite photocatalysts exhibited remarkably enhanced adsorption and catalytic degradation performance for MB removal under visible light irradiation. The improved catalytic performance of the g-C₃N₄@CaCO₃ photocatalyst can be attributed to alterations in the morphology and the formation of cyano defects, which facilitate the absorption and utilization of visible light, as well as the separation of photogenerated carriers. This work provides a strategy to develop a novel g-C₃N₄@CaCO₃ photocatalyst with enhanced performance for efficient treatment of dyeing wastewater.

期刊介绍： Launched in January 1998, Inorganic Chemistry Communications is an international journal dedicated to the rapid publication of short communications in the major areas of inorganic, organometallic and supramolecular chemistry. Topics include synthetic and reaction chemistry, kinetics and mechanisms of reactions, bioinorganic chemistry, photochemistry and the use of metal and organometallic compounds in stoichiometric and catalytic synthesis or organic compounds.
