A non-enzymatic photoelectrochemical (PEC) glucose sensor based on nanoporous bismuth vanadate (BiVO 4 ) electrode is fabricated on fluorine doped tin oxide by electrochemical deposition. The photogenerated holes of BiVO 4 show a strong oxidizing ability, with adsorption of glucose on the surface of BiVO 4 , agreeing well with the classical Langmuir adsorption model. Under visible light irradiation, the glucose molecules adsorbed on the BiVO 4 electrode surface can be oxidized by the photogenerated holes, which results in increased photocurrent. The fabricated BiVO 4 non-enzymatic photoelectrochemical sensor shows outstanding catalytic activity, favourable selectivity, good reproducibility, and long-term stability for …
