Abstract
Abstract In this work, a photoelectrochemical (PEC) self-powered sensor based on ITO/NiO/RGO/BiOI electrodes for the detection of glucose was constructed. NiO nanosheets array were grown on an indium tin oxide (ITO) electrode by methods of hydrothermal synthesis, and RGO was successfully loaded by calcination. Then the different layers of BiOI was coated on the above electrode by chemical bath. BiOI has a catalase-like action and produces a special synergistic dual catalytic mechanism with glucose oxidase. PDDA (Poly dimethyl diallyl ammonium chloride) acts as an intermediate linker to connect the modified electrode with glucose oxidase. BiOI has a catalase-like action and produces a special synergistic dual catalytic mechanism with glucose oxidase. Under the optimal experimental conditions, the self-powered PEC sensor has a good photoelectric response in the linear range of 1.0 × 10−7–1.0 × 10−1 mol/L, and the detection limit is 4.7 × 10−8 mol/L. The PEC self-powered sensor has good stability, high sensitivity and excellent reproducibility. On this basis, the sensor has also obtained satisfactory results for ultrasensitive and simple detection of glucose injections.
