Abstract

Abstract:

Photocatalytic CO₂ reduction， as a new green technology， is expected to simultaneously solve the energy crisis and environmental pollution problems，so it has attracted much attention in recent years.As one of the most widely studied photocatalysts， TiO₂ still has the disadvantages of limited light absorption range and rapid recombination of photogenerated carriers.Cu can be doped into TiO₂ with hollow structure by pyrolyzing Ti-based MOF（metal-organic framework） precursors.The structure and morphology of the as-prepared photocatalysts were analyzed by X-ray diffraction（XRD），scanning electron microscopy（SEM），and transmission electron microscopy（TEM）.In addition， the structure-activity relationship was investigated using UV-Visible diffuse reflection spectroscopy（UV-Vis DRS） and photoluminescence spectroscopy（PL）.The experimental results revealed that Cu doping could improve the light absorption capacity and promote the separation of photogenerated carries， thereby improving the performance in photocatalytic CO₂ reduction.When Cu doping mass fraction was 0.50%，the catalyst exhibited the best performance，and the yield of CO and CH₄ reached 6.3 μmol/g and 1.6 μmol/g， respectively.

Key words: photocatalysis, CO₂ reduction, Cu-doped hollow TiO₂
