摘要

Co-doped NH2-MIL-125(Ti) catalysts [Co/NH2-MIL-125(Ti)] are developed for the photocatalytic reduction of CO2 upon visible-light irradiation. Compared with NH2-MIL-125(Ti), Co/NH2-MIL-125(Ti) exhibits a significantly enhanced activity in CO2 reduction, due to the fact that the doping of Co nanoparticles onto NH2-MIL-125(Ti) can promote the visible-light harvesting and electron transfer. In addition, when benzylic alcohols as electron donors, instead of triethanolamine (TEOA) which is often used as a sacrificial agent, are added into the reaction system, Co/NH2-MIL-125(Ti) can simultaneously catalyze CO2 reduction to formic acid (HCOOH) and the selective oxidation of the benzylic alcohols to the corresponding aldehydes, making the proposed process more economical and environment-friendly.
