摘要
Photoelectrochemical(PEC)sensor is an emerging technology in analysis as the advantage of fast re-sponse,high sensitivity and uncomplicated operation.In this study,an effective label-free PEC sensor for bisphenol A(BPA)detecting is constructed,in which Zn In_(2)S_(4)/g-C_(3)N_(4)heterojunction is prepared via a sim-ple hydrothermal method.The characterization outcomes display that the formation of p-n heterojunction helps for promoting the separation efficiency of photo-generated carrier.Under visible light irradiation,the Zn In_(2)S_(4)/g-C_(3)N_(4)modified electrode exhibits broader liner range from 0.05 mmol/L to 30 mmol/L and lower detection limit of 0.016μmol/L(S/N=3)with remarkable stability and reproducibility of detection BPA under visible light irradiation.Furthermore,the constructed PEC sensor displays favorable potential for detection of BPA in practical applications.
