Fundamentals and applications of photocatalytic CO2 methanation [PDF]
Nature Communications, 2019 AbstractThe extraction and combustion of fossil natural gas, consisting primarily of methane, generates vast amounts of greenhouse gases that contribute to climate change. However, as a result of recent research efforts, “solar methane” can now be produced through the photocatalytic conversion of carbon dioxide and water to methane and oxygen.
