Development of photocatalysts and system optimization for CO2 photoreduction

Abstract Increasing concentrations of CO2 levels in the atmosphere are causing global warming and adverse global environmental changes. Significant efforts have focused on decreasing the CO2 emissions to the atmosphere. The utilization of CO2 via photocatalytic reduction has the potential to mitigate emissions, while producing solar fuels, such as H2, CO, CH4, CH3OH, and value-added chemicals.
