Preparation and investigation of physicochemical properties of g-C3N4/LaCoO3 heterostructure for photocatalytic dye degradation

Photocatalytic decomposition of pollutant is the most optimal approach for the wastewater remediation. Nevertheless, the development of a catalyst that is both cost-effective and extraordinarily active remains a substantial challenge. The g-C₃N₄/LaCoO₃ heterostructure were prepared by different weight percentages of g-C3N₄ (15, 30, 45, 60, and 75 wt%). The g-C₃N₄ and LaCoO₃ were exhibits hexagonal and rhombohedral crystal structure respectively. The g-C₃N₄/LaCoO₃ heterostructure exhibits tiny particles were anchored over the coarse like structure. The g-C₃N₄/LaCoO₃ heterostructure promote visible light harvest and inhibit charge carrier recombination than the bare LaCoO₃ and g-C₃N₄ and which helps to enhance the organic pollutant elimination performances. The g-C₃N₄/LaCoO₃ heterojunction exhibits superior methylene blue degradation when compared to bare LaCoO₃ and g-C₃N₄. Furthermore, the composite of LaCoO₃/g-C₃N₄–60 wt% exhibits higher photocatalytic activity and exceptional stability were observed under visible light irradiation.
