However, its practical implementation requires significant advancements in terms of catalytic efficiency, charge separation, and product selectivity. In this study, we design and synthesize Bi₂S₃/Sn-doped TiO₂ nanofibers (Bi₂S₃/Sn-TiO₂ NFs) by employing electrospinning and hydrothermal methods to achieve superior photocatalytic CO₂ reduction under ultraviolet-visible (UV-Vis) irradiation. Under simulated solar light, Bi₂S₃/Sn-TiO₂ NFs exhibit threefold enhancement in CH₃OH production (529 µmol/g·h) compared to that of Sn-TiO₂ NFs (188 µmol/g·h) and pristine TiO₂ NFs (80 µmol/g·h). This significant improvement is attributed to the synergistic effect of 1D Sn-TiO₂ NFs structure, which facilitates rapid charge transport, and 0D Bi₂S₃ nanoparticles, which enhance visible light absorption and act as active sites for CO₂ adsorption and reduction. The formation of an optimized S-scheme heterojunction promoted efficient interfacial charge transfer, suppressed recombination losses, and ensured prolonged photocatalytic stability.

The presence of H₂ maintained ASR near steam electrolysis levels, while CO increased it towards CO₂-electrolysis values. DRT analysis revealed additional peaks related to CO₂/CO processes.
