Abstract

Using D113 macroporous ion exchange resins (IER) as carriers, glucose as reductant, cuprous oxide (Cu2O) nanoparticles were formed in situ in the channel and surface of ion exchange resin by isothermal oscillation method and hydrothermal synthesis method, furtherly Cu2O-loaded ion exchange resin composites, abbreviated as Cu2O@IER, were successfully prepared. Three products were obtained under only changing the dosage of glucose, marked as Cu2O@IER-0.5g, Cu2O@IER-1.0g, and Cu2O@IER-1.5g, respectively. Three products were characterized by XRD, SEM, and EDS. Their photocatalytic performance under simulated sunlight irradiation was studied using polyacrylamide (PAM) as the target pollutant. Experimental results showed that the size of Cu2O in the three composite materials was at the nanometer level, with grain sizes ranging from 20 to 30 nm. The crystal form of Cu2O in Cu2O@IER-1.5g was complete, and the purity was high. Cu2O@IER-1.0g presented the best PAM degradation effect with the highest degradation rate of 66.37%.
