Abstract
Ag@AgCl-MWCNT nanocomposites were prepared using an in situ oxidation method. Different techniques, such as XPS, XRD, Pl, TEM, UV-vis spectroscopy, and BET, were employed to characterize Ag@AgCl and Ag@AgCl-MWCNT nanocomposites. The analytical results demonstrated that the addition of MWCNT improved the dispersion of Ag and AgCl. The photocatalytic performance of Ag@AgCl and Ag@AgCl-MWCNT nanocomposites was studied by measuring the degradation of cyanide under visible light irradiation. The addition of MWCNT to Ag@AgCl increased the photocatalytic performance of the nanocomposites. Specifically, the photocatalytic degradation of Ag@AgCl nanoparticles was lower than that of Ag@AgCl-MWCNT nanocomposites because the addition of MWCNTs promoted the separation of electrons and holes. The degradation of cyanide by Ag@AgCl-MWCNT nanocomposites followed first-order reaction kinetics.
