Photocatalytic performance of DyCrO3/r-GO and Dy0.5Ho0.5CrO3/r-GO nanocomposites: a comparison

DyCrO 3 / r -GO (DCO/ r - GO) and Dy 0.5 Ho 0.5 CrO 3 / r -GO (DHCO/ r -GO) nanocomposites consisting of 5 wt.% r -GO were synthesized by the sol–gel method, and their photocatalytic performance was studied on methylene blue (MB) and rhodamine B (RhB) dyes under solar irradiation. The bandgap energy...

Zusammenfassung:DyCrO 3 / r -GO (DCO/ r - GO) and Dy 0.5 Ho 0.5 CrO 3 / r -GO (DHCO/ r -GO) nanocomposites consisting of 5 wt.% r -GO were synthesized by the sol–gel method, and their photocatalytic performance was studied on methylene blue (MB) and rhodamine B (RhB) dyes under solar irradiation. The bandgap energy of DCO/ r - GO and DHCO/ r -GO nanocomposites was found to be 2.63 eV and 2.58 eV, respectively. The DCO/ r -GO and DHCO/ r - GO nanocomposites demonstrated remarkably higher photocatalytic activity than DCO and DHCO nanoparticles. The DCO/ r -GO and DHCO/ r -GO nanocomposites furnished 69.6% and 71.6% degradation of the MB dye and 87% and 96% degradation of RhB dye within 180 min under direct sunlight.
