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.
