Solar-driven photoelectrochemical CO2 reduction represents a promising approach for the production of renewable liquid fuel but is limited by low photocurrent, need an external bias, and carbon efficiency. This work employs TiO2-CdS/Se-ZnSe/S photoanode to drive sulfur oxidation reaction, achieving photocurrent density 12.7 mAcm-2 under AM 1.5G illumination with 87% retention after 100 h continuous operation. Furthermore, through tailoring adsorption capability *OCHO intermediate, Cu6Sn5 catalyst exhibits Faradaic efficiency 92.8% formic acid at -1.15 V in acidic media maintains stability above 90% during 120-h test. Finally, constructed system achieves bias-free HCOOH delivers yield up 172.9 µmolh-1cm-2 over 85-h long-term test, outperforming conventional solar-driven systems. These findings highlight cost-effective strategy provide valuable design concepts insights into development
