Abstract

Abstract: In this research, four bimetallic nanocomposites (BNCs) of copper and silver with weight ratios (0.9:0.10, 0.92:0.08, 0.94:0.06, 0.96:0.04) formulated and specified as (Cu0.90@Ag0.10), (Cu0.92@Ag0.08), (Cu0.94@Ag0.06), and (Cu0.96@Ag0.04) were prepared via the green synthesis in the presence of Citrus paradisi extract as a low cost, simple and environmentally friendly method. The as-prepared Cu@Ag BNCs were identified by FTIR, XRD, EDX, FE-SEM, and EDX mapping analyses. The FTIR analysis was performed to determine the functional groups in Cu@Ag BNCs. EDX analysis confirms the existence of Cu and Ag in BNCs. These Cu@Ag BNCs were used as catalysts for the photodegradation process of methyl orange (MO) and indigo carmine (IC) as the anionic organic dye. The effect of parameters such as different weight percentages of BNCs constituent metals, the amounts of photocatalyst and hydrogen peroxide on the degradation rate of MO and IC under visible light was investigated and their optimal values were determined. The optimized conditions for removal of the dyes in the natural pH and 0.005 g of photocatalyst Cu0.90@Ag0.10 BNCs reached for degradation dyes MO and IC to 90.0% and 100% respectively.
