CuO Nanoparticle-Decorated TiO₂-Nanotube Heterojunctions for Direct Synthesis of Methyl Formate via Photo-Oxidation of Methanol.

ABSTRACT: Methyl formate is widely employed as one of the important organic intermediates in C1 chemistry and as an environmentally benign chemical in the emerging area of "green chemistry". We here study the catalytic effectiveness of CuO/TiO₂-nanotube nanocomposites for the direct synthesis of methyl formate via methanol photo-oxidation in this paper. The CuO/TiO₂-nanotube nanocomposites with 7% CuO weight loading give a promising photocatalytic performance (over 93.3% methanol conversion and 89.4% methyl formate selectivity) at 25 °C under 365 nm UV irradiation. The turnover frequency and the apparent quantum efficiency reach up to 22.9 mol_methanol g_cat ^-1 h^-1 and 57.6% over 7% CuO/TiO₂-nanotube, respectively, whi
