This invention is a novel indium-based photocatalyst that is capable of reducing CO2 (carbon dioxide) into CO (carbon monoxide). Currently there are 5.5 billion metric tons of CO2 produced annually with 2 billion tons consumed worldwide. CO2 emissions account for 82% of all US greenhouse gas emissions. The market for CO2 sequestration consists of a spectrum of offerings through either storage or recycling. Discovering a material capable of photocatalytic reduction of CO2 is a crucial step for the solar fuels economy.
