Fe and Cu containing SBA-15 composites (Fe-Cu/SBA-15) were successfully prepared by atomic implantation method. The samples were characterized by XRD, SEM, TEM, FTIR, BET, EDX and XPS. From these results, it reveals the existence of the both (Fe 2+ and Cu 2+) metals ions in the SBA-15 framework. A series of Fe x-Cu y/SBA-15 composites with different Fe content degradation of 4, 4-Dichloro-Diphenyl-Trichloroethane (DDT) under the simulated sun-light irradiation using H 2 O 2 as an oxidant agent. This clearly indicated that Cu+ reduce Fe 3+ to Fe 2+ and consequently, enhancing the catalytic activity. Effects of pH, H 2 O 2 concentration and catalyst dosage were investigated. The best conditions were found to be pH of 5; 3 mM of H 2 O 2 concentration, 0, 4 g L− 1 catalyst and reaction time of 4 h at room temperature. The novel Fe-Cu/SBA-15 composite exhibited highly photocatalytic performance of DDT degradation and the conversion reached to the value of 92.3% for the 10Fe-2Cu/SBA-15 composite after 4 h of reaction.
