Solar radiation accounts for 5% of UV and 43% of visible radiation which has not yet been exploited. So, the development of visible light driven photocatalyst has become one of the most challenging topics today which can address the problems recombination of charge carriers during light illuminatiorl and the problems of electron transport to the substrate in experimental point of view and practically it can resolve the enery and environmental problems. AgP having band gap energy 2.1 eV is reported to be a visible light semiconductor. But, the main drawback with this material is that it undergoes photocorrosion during light illumination and it has very low adsorptive capacity. So, we have thought of coupling RGO with AgP in a very novel one-pot photo-reduction technique in presence of a sacrificial agent like dry ethanol. The dirty green semiconducting material thus collected was tested towards adosoptive photodegradation of textile dyes. The results showed that 4 wt.% RGO- AgP can degrade 100, 76, 98.57, 67.88, 69.92% of RhB, Rh6G, MB, CR and MO, respectively within only 05 min under VISL illumination over 1.5 g/L of catalyst. |
