In this paper we will report our preliminary results on
such attempt. A modified preparation method has been
conducted to synthesize a Cu0/TiO2, CuI/TiO2 and CuII/
TiO2 catalysts. Characteristics of the catalysts were
investigated by XRD, UV–vis diffuse reflectance spectroscopy
(DRS), SEM/EDAX/Mapping, BET and
AAS. Activity test of the catalysts was conducted to reduce
CO2 in a batch slurry photo reactor accomplished
with UV black light lamps.
