Abstract

N, S co-doped activated carbon (ACNS) was obtained by modification with thiourea and cerium oxide supported on activated carbon (Ce/AC, and Ce/ACNS) were prepared and worked as catalyst for catalytic ozonation of benzoic acid. The catalysts were characterized by elemental analysis, N2 adsorption-desorption, the pH at the point of zero charge (pHpzc),) and X-ray photoelectron spectroscopy (XPS).In contrast with Ce/AC, Ce/ACNS increased the catalytic activity. The enhanced catalytic performance was attributed to the presence of the N and S atoms may improve the electron density on AC surface and therefore enhance the amount of Ce3+ on catalyst surface.
