This study explores the enhancement of α-Fe2O3 (hematite) nanorod arrays for photoelec-trochemical applications by constructing a Cu2ZnSnS4 (CZTS) heterojunction. While offers good stability, low cost, and environmental benefits, its efficiency is limited slow oxygen evolution kinetics, high carrier recombination rates, conductivity. By introducing CZTS, material with strong light absorption charge transport properties, we enhance separation photogenerated carriers, reduce transfer resistance, increase concentration, thereby boosting overall photoelectrochemical performance. The experimental results show that modified FC-15 photoanode achieves photocurrent density 3.40 mA/cm2 at 1.60 V vs. RHE, substantial compared to 0.40 unmodified α-Fe2O3. Band gap analysis reveals reduced band in material, enhancing photoelectrocatalytic In water-splitting tests, hydrogen production rate 41.6 μmol/cm2/h, which significantly improved over sample 5.64 μmol/cm2/h. These findings indicate CZTS/α-Fe2O3 heterojunction effectively promotes separation, enhances transport, improves absorption, substantially increasing photocatalytic efficiency. approach new insights technical strategies developing materials potential renewable energy.
