Abstract
The present invention discloses a dual functional photocatalytic device and a process for photocatalytic co-conversion of CO2 and H2O to value added products in direct sunlight. More particularly, the present invention relates to efficient and continuous process for the photocatalytic co-conversion of a mixture of CO2 and water into methanol, formaldehyde, in the presence of newly developed dual-functional photocatalyst device. The present invention is to provide dual-functional photocatalyst device, along with a co-catalyst and integrating them into a photocatalytic device using artificial leaf approach wherein said device is in the form of thin film working under wide spectrum of solar radiation at ambient conditions. Additionally it is easy to scale up the photocatalyst device size from 1 cm2 to 10 cm2 size and process is tuneable to generate desired products.
