1,2-Dichloroethane(DCE) is one of the maximum critical chlorinated unstable natural pollution in waste liquid and has been indexed as a tough pollutant via way of means of numerous regulatory groups global. It is substantially used as a precursor with inside the petrochemical corporation to provide vinyl chloride monomers for the manufacturing of polyvinyl chloride (PVC). In this study, g-C3N4 photocatalysts synthesized by traditional thermal polycondensation methods have small specific surface areas and wide band gaps; these defects severely suppress the photocatalytic activity. Our research has focused on the optimization and modification of g-C3N4. by doping some bimetallic elements such as Ag and Cu Bimetals which alter the photochemical properties of g-C3N4, in particular, narrow the band gap and expand photoabsorption into the visible range, which improves the photocatalytic performance. quantum efficiencies, illumination area and increasing specific power irradiance. The tendencies of synthesized Ag-Cu/C3N4 have been showing the use of FTIR, XRD, EDX, and TEM strategies. This confirms the presence of enormous shapes with inside the shape of quantum dots and a 2-D Nanosheet. The degradation of DCE changed into showed through the dimension of UV-Visible spectra of degradable product and indicated the pseudo-first-order-kinetic response. Another sturdy indication of deterioration of DCE is the measuring of Cl ion liberated from degradation via titration.
