The catalysts of Zn doped OMS-2 nanorods with the Zn/Mn atomic ratios of 0.052, 0.056, and 0.073 were synthesized through the reaction among Zn(NO3)2, KMnO4, and Mn(NO3)2 at 75 °C via changing the molar ratios of Zn(NO3)2/KMnO4/Mn(NO3)2 in reactants. The Zn doped OMS-2 catalysts were characterized with ICP, XRD, TEM, BET, XPS, UV–Vis-IR, and CO-TPR. The catalysts demonstrate excellent photothermocatalytic activity for CO abatement with UV–Vis-IR irradiation. The Zn doping substantially promotes the photothermocatalytic activity of OMS-2. In comparison with TiO2(P25), the CO2 pr...
