| Outline of Final Research Achievements |
We developed the following new photocatalytic systems for CO2 reduction: (1) mix systems of Re-rings and various metal-complex catalysts, which are the most efficient photocatalysts in the reported ones up to now, (2) Ag-deposited metal-oxide photocatalysts, which showed high selectivity of CO2 reduction (higher than 50%), (3) a supramolecular-photocatalyst loaded mesoporous organosilica, which had high light-harvesting ability, i.e., about ten times higher efficiency of CO2 reduction compared to the same photocatalyst in the mesoporous silica gel.
The rate of electrochemical reduction of CO2 by using conducting mesoporous carbon electrode could be improved by coat with Ag.The enzyme activity of FDH could be 560 times improved by using 4,4’-bipyridine with two amino groups as an electron mediator compared to that using the coenzyme NADH.
