摘要：

A new method for the reduction of CO2 to CH3OH coupled with selective alcohol oxidation using a photocatalytic method has been developed in the present paper. CO2 as the oxidant was reduced to methanol by photo-induced electrons, and aromatic alcohols were used as the reductants to react with photo-generated holes and were converted to aromatic aldehydes with high selectivity. The maximum conversion of aromatic alcohol to aldehyde was 91.7% with a selectivity of 98%, and the highest yield of methanol was 358.7 mu mol g(-1). This study could provide a valuable method not only for carbon dioxide conversion into fuel which could remission energy shortages, but also for the selective oxidation of alcohols to produce aldehydes.
