CO2 photoreduction integrated with oxidative coupling of amines over WO3 /Cu(BTC) nanocomposite

Here, we report an efficient integrated CO2 photoreduction to methanol accompanied with the simultaneous oxidation of benzyl amines to corresponding imines using quadrangular WO3 nanoplates grafted with Cu(BTC) as a photocatalyst under visible light, enabling to provide efficient use of the photogenerated electrons and holes. Under the optimized reaction conditions, the maximum yield of methanol and N-(4-methoxybenzyl)-1-(4methoxyphenyl)methanimine was found to be 642 mu mol-g - 1 and 98 %, respectively. The developed integrated dual functional system comprising CO2 reduction coupled with the oxidative organic synthesis opens a new window for value chain up gradation at both ends using sustainable solar energy.
