| Outline of Annual Research Achievements |
We aimed to achieve visible light sensitive CO2 photoreduction based on the combination of a Z-Scheme light harvester system and highly selective co-catalys.
As light harvesters, CaFe2O4(CFO) photocathode and WO3 nanotrees photoanode were prepared. The film thickness and annealing temperature of the CFO photocathode were further modified to achieve high photocurrent density.
As co-catalyst, after composition modification and electrochemical screening, Cu5Zn8 nanoparticles were developed and proved to be active for selective HCOOH generation. By using an ink methode, these NPs can be generally decorated on various light harvesters under moderate conditions.
At last, HCOOH was selectively generated by the combined system under 0.5V over-potential and visible light irradaition.
