A Label-free Photoelectrochemical Sensor Based on Bi2S3@Nitrogen Doped Graphene Quantum Dots for Ascorbic Acid Determination
文献摘要：
We report a photoelectrochemical(PEC)sensor for selective detection of ascorbic(AA)by introducing Z-scheme Bi2S3@nitrogen doped graphene quantum dots(Bi2S3@NGQDs)heterojunctions as efficient photoactive species.The Bi2S3@NGQDs were successfully prepared by a simple hydrothermal process,and the microstructures and components were investigated by various characterized techniques.The photocurrent of the Bi2S3@NGQDs-based sensor increased significantly in the presence of AA and showed excellent selectivity and stability for AA detection in the presence of some other antioxidants and small molecules.A wide linear range of 0.1-5μmol/L and 5-1380 μmol/L was achieved for the AA detection with a detection limit of 36 nmol/L(S/N=3).Moreover,the proposed PEC sensor achieved the determination of AA in real red peppers and commercially available vitamin C tablets samples.
