Abstract The construction of nanostructured heterostructure is a potent strategy for achieving high‐performance photoelectrochemical (PEC) water splitting. Among these, constructing BiVO 4 ‐based stands out as promising method optimizing light‐harvesting efficiency and reducing severe charge recombination. Herein, we present novel approach to fabricate type II core/shell Bi 2 S 3 /BiVO using electrolytic deposition successive ionic layer adsorption reaction (SILAR) methods. We identify the difference in fermi energy UV‐Vis spectroscopy, X‐ray photoelectron PEC measurements. This redistribution charges due induces an interfacial built‐in electric field from , reinforcing photogenerated hole transfer kinetics . exhibits superior photocurrent (6.0 mA cm −2 ), enhanced separation (85 %), higher open‐circuit photovoltage (350 mV). Additionally, displays prolonged average lifetime (1.63 ns), verifying this heterojunction could boost carriers’ migration via additional nonradiative quenching pathway. Furthermore, lower photoluminescence (PL) intensity demonstrates beneficial boosting migration.
