Abstract
A combination of mesoporous silica with an LaCuS2-graphene composite has been prepared by a self-assembly method in support of the CTAB surfactant as the structure creator and basic medium. The characterization was investigated using XRD, SEM, TEM, HR-TEM, EDS, XPS, Raman, and DRS analysis. The pore size of the as-fabricated composite was calculated to be 5.83â¯nm by the nitrogen adsorption/desorption isotherms. In addition, the photocatalytic properties revealed that the mesoporous SiO2/LaCuS2-graphene catalyst presented a good result for the photocatalytic activity of organic dyes and gallic acid under visible light irradiation. Moreover, the as-prepared mesoporous SiO2/LaCuS2-graphene nanocomposite exhibited a good photodegradation rate for a cationic organic dye group under a pH medium of 11. The photocatalytic performance of the phenol compound representation presented a good result, and the optimum amount of the catalytic for the gallic acid photocatalytic activity is 0.05â¯g. In addition, the mesoporous SiO2/LaCuS2-graphene catalyst can be exploited for the application of solar energy conversion with high hydrogen production capacity.
