One of the major problems concerning environmental pollution and global warming is a rapid escalation in the level of carbon dioxide in atmosphere. The atmospheric CO2 level can be reduced by converting it into useful products via thermochemical and photochemical processes. Amongst these conversion processes, the photochemical conversion is a cost effective and preferred process for the photoreduction of CO2 into useful liquid fuels like methanol, formaldehyde, and methane gas. Here, we synthesized CuO-TiO2 nanostructure, a hybrid material photocatalyst and tested for CO2 photoreduction. The synthesis process involves the formation CuS nanostructure using electrochemical anodization followed by embedment of titanium isopropoxide as Ti precursor. The oxidation of the nanosctuctre is performed at temperature of 400 °C oxidizing Cu and Ti to form CuO-TiO2 nanostructures. |
