Photoelectrochemical reduction of carbon dioxide over copper ferrite - graphene oxide composites

Recycling of atmospheric CO2, the ultimate by-product of all processes involving oxidation of carbon compounds, for use as fuel is one of the most promising alternatives to combat global warming and energy crisis. Photocatalysis (PC) is a very promising technique for reducing CO2 into hydrocarbon fu...
