Abstract
In this study, meso-structured rGO(2%)-modified BimOnClz nanophotocatalyst was designed through a simple sono-solvothermal method, employing in the photodegradation of dyed contaminants along with the solar-light irradiation. Its properties were described using XRD, Raman, BET-BJH, and FESEM analyses. The consequences revealed 99.8% and 84.7% degradation for 8 mg/L rhodamine B and 20 mg/L acid orange 7 after 120 min illumination. These consequences were ascribed to the increase of the surface adsorption of contaminant molecules, increasing the accessible active sites, decreasing band gap and the enhancement of light absorption features, separation and transmission of charge carriers and reducing recombination rate of them.
