Carbon dioxide (CO2) conversion has been attracted many concerns due to the high greenhouse gas level in the atmosphere. The photocatalytic reduction of CO2 is an attractive technology that uses directly solar energy to convert CO2 into valuable chemicals in an environment-friendly way. However, the effective reduction process is not easy because the cathodic process has a high overpotential barrier with low selectivity to a certain product. Recent research focused on the utility of co-catalyst to improve the photocatalytic performance, while effect of inorganic surface ligand remained largely unexplored. To the best of our knowledge, the only example where the inorganic ligands was used for photocatalytic CO2 reduction is the use of Tetrafluoroborate (BF4-) for the enhancement of yield. In this study, the effect of not only the capping ionic ligands but also the cation ions on the photocatalysis will be studied. |
