Crafting charge transfer channels at titanium dioxide (TiO2) based photoanodes remain a pressing bottleneck in solar-to-chemical conversion technology. Despite the tremendous attempts, TiO2 as the promising photoanode material still suffers from sluggish charge transport kinetics. Herein, we propose an assembly strategy that involves the axial coordination grafting metalloporphyrin-based photosensitizer molecules (MP) onto the surface-modified TiO2 nanorods (NRs) photoanode, forming the composite MP/TiO2 NRs photoelectrode. As expected, the resulted unique MPB/TiO2 NRs photoelectrode displays significantly improved photocurrent density as compared to TiO2 NRs alone and MPA/TiO2 NRs photoelectrode. Scanning …
