Sacrificing nothing to reduce CO2

Photocatalytic systems for CO2 conversion to fuels tend to suffer from low selectivity, and sacrificial reagents or external bias are often required to make the reaction work. Now, a wireless and stand-alone photocatalyst device is demonstrated that converts CO2 and water into formate and O2 using solar energy without external bias.
