Abstract

Selective photocatalytic reduction of CO ₂ into methanol, using 355 nm UV laser as a light source, has been studied for the first time. An alternate route for the photocatalytic reduction of CO ₂, based on thermodynamic viability of the process, has been suggested. It was observed that the formation of methanol from CO ₂ is a reversible process and the methanol produced during the photocatalytic process degrades to generate hydrogen and CO ₂ again; which hampers the over all conversion rate. The measurements on pH and hydrogen production during the course of photocatalytic reduction were valuable in explaining the conversion process.
