Systematic study of TiO/ZnO mixed metal oxides for CO photoreduction.

A two component three degree simplex lattice experimental design was employed to evaluate the impact of different mixing fractions of TiO and ZnO on an ordered mesoporous SBA-15 support for CO photoreduction. It was anticipated that the combined advantages of TiO and ZnO: low cost, non-toxicity and combined electronic properties would facilitate CO photoreduction. The fraction of ZnO had a statistically dominant impact on maximum CO adsorption ( = 22.
