Abstract

Copper or cobalt incorporated TiO2 supported ZSM-5 catalystswere prepared by a solgelmethod, and thenwere characterized by XRD, BET, XPS andUVvis diffuse reflectance spectroscopy. Ti3+was themain titaniumspecie in TiO2/ZSM-5 and CuTiO2/ZSM-5,whichwill be oxide to Ti4+ after Cowas doped. With the deposition of Cu or Co, the efficiency of the CO2 conversion to CH3OH was increased under low energy irradiation. The peak production rate of CH3OHreached 50.05 and 35.12 μmol g?1 h?1, respectively. High photo energy efficiency (PEE) and quantum yield (σ) were also reached. The mechanism was discussed in our study.
