This is a PhD research project in Chemical Engineering. Solar fuels produced from the photocatalytic conversion of CO2 using H2O is a means of addressing global energy demands without contributing to existing net CO2 emissions. However, since CO2 is very stable, its conversion to carbon based fuels requires substantial input of energy. The challenge here is improving conversion efficiency to make the process economically viable and this has led to extensive research on the development of highly efficient photocatalysts and scalable reactor designs capable of effective photon utilization for catalyst activation.This project applies novel multidisciplinary approaches to photocatalysis. The research will focus of the photo-catalytic behaviour of nanostructured visible light photocatalysts over supports with promising optical and electronic properties.
