Highly sensitive detection of chromium (VI) by photoelectrochemical sensor under visible light based on Bi SPR-promoted BiPO4/BiOI heterojunction

•Bi surface plasmon resonance (SPR)-promoted BiPO4/BiOI is synthesized by hydrothermal method.•The Bi-BiPO4/BiOI composites have excellent PEC performance.•The PEC sensor shows outstanding performances for hexavalent chromium detection. In this work, Bi surface plasmon resonance (SPR)-promoted BiPO4...
