The narrow bandgap semiconductor Sb2S3 has been extensively utilized in solar cells for its impressive light absorption coefficient and carrier mobility. However, a large number of deep energy defects provide recombination sites that limit photoelectrochemical (PEC) performance. In this study, nanorods (NRs) CdSe quantum dots (QDs) were successfully prepared, Sb2S3/CdSe-annealed quasi-one-dimensional heterojunction photoanodes with the S-scheme constructed. composite photoelectrode achieves 12 times increase photocurrent density compared to 0.4 mA cm–2 photoelectrode. Overall, synergistic effect [hk1]-oriented NRs promotes transport, achieving spatial separation photogenerated carriers efficiently weakening electron–hole pair. This study provides simple method low-cost development [hk1] orientation an idea enhance PEC water splitting direction.
