AB - Developing photoelectrochemical catalysts to convert CO2 into chemical feedstocks presents a promising approach for clean energy storage by harnessing solar energy. This study examines the potential of a Zn-based coordination polymer gel (CPG), incorporating terpyridine (TPY) and tetrathiafulvalene (TTF) moieties (Zn-TPY-TTF CPG), for artificial photosynthesis. In this novel approach, Zn-TPY-TTF CPG serves as both photoanode and dark cathode material in a photoelectrochemical (PEC) cell. When combined with BiVO₄ (BVO) nanostructures to fabricate a heterojunction photoanode, Zn-TPY-TTF CPG significantly enhances PEC water-oxidation, delivering a fourfold increase in photocurrent density at 0.6 V versus Ag/AgCl compared to pristine BVO. Kelvin Probe Force Microscopy (KPFM) confirms improved carrier separation and transport due to favorable band alignment between BVO and Zn-TPY-TTF CPG. PEC CO₂ reduction experiments in an H-cell demonstrate a remarkable 43
