Tunable Syngas Production from CO2 and H2O in an Aqueous Photoelectrochemical Cell

Syngas, the mixture of CO and H₂ , is a key feedstock to produce methanol and liquid fuels in industry, yet limited success has been made to develop clean syngas production using renewable solar energy. We demonstrated that syngas with a benchmark turnover number of 1330 and a desirable CO/H₂ ratio of 1:2 could be attained from photoelectrochemical CO₂ and H₂ O reduction in an aqueous medium by exploiting the synergistic co-catalytic effect …
