Novel Photocatalyst Effectively Turns Carbon Dioxide Into Methane Fuel With Sunlight

Carbon dioxide (CO2) is one of the major greenhouse gases causing global warming. If carbon dioxide could be converted into energy, it would be killing two birds with one stone in addressing the environmental issues. A new photocatalyst is developed recently, which can produce methane fuel (CH4) selectively and effectively from carbon dioxide using sunlight. According to this research, the quantity of methane produced was almost doubled in the first 8 hours of the reaction process.
