Multi-functionalized TiO2 photocathodes were established for CO2 reduction with Co-Pi/W:BiVO4 film as counter electrode. In photocathode, Pd nanoparticles catch protons, dye absorbs solar energy, and amine ligands capture and activate CO2. The Faradaic efficiency of PEC cell exceeds 1000% due to the synergistic effect of photo- and electro-catalytic process.
