Fabrication of AgSrtio3/G-C3n4 Heterojunctions for H2 Production and the Degradation of Pesticides Under Visible Light

In the present study, we have fabricated Ag-doped STO/g-CN heterojunctions and the fabricated heterostructure was characterized. The photo-electrochemical performance including PL, photocurrent, (EIS), and TR-FS were also determined. The fabricated nanocomposites were used for the photocatalytic hydrogen production and degradation of the pesticide, Dicofol. Photocatalytic properties (bandgap), band potentials (E VB and E CB ), and band structures were determined using Mott-Schottky and DSR study. The hydrogen production rate of Ag(3)STO/g-CN was found to be 645.62 µmol.g -1 .h -1 which is about 2 times higher than that of pristine STO/g-CN. The formed intermediates and catalytic mechanism for the degradation of Dicofol have supported DFT calculation and LC-MS spectra. The results revealed that the fabricated nanocomposites exhibit ultrafast photocatalytic activity and about 92.2% degradation was noticed within 60 min. The reusability was carried out and the photocatalyst retains its catalytic activity about 95% after 6 cycles
