▎ 摘　　要

A novel non-enzymatic photoelectrochemical (PEC) glucose sensor was first constructed based on the unique two-dimensional (2D) bismuth oxychloride-graphene nanohybrid sheets (BiOCl-G NHS). We have utilized a facile hydrothermal approach for the preparation of BiOCl-G NHS. Results from cyclic voltammetric and differential pulse voltammetric measurements revealed that the BiOCI-G NHS electrode is capable of generating photocurrent for glucose when its surface is irradiated with a light source (wavelength=365 nm). The photocurrents produced for the presence of glucose at the bias potential of +0.50 V showed a linear dependence on glucose concentration in the range between 0.5 and 10 mM and had a detection limit of 0.22 mM. The PEC detection of glucose at BiOCI-G NHS was not influenced by the presence of other common interfering species. The glucose levels, as determined by the BiOCI-G NHS sensor, agreed well with those obtained by the commercial glucometers. This novel non-enzymatic PEC glucose sensor exhibited good performances, such as a wider concentration range (500 mu M-10 mM), high sensitivity (1.878 mu M mM(-1) cm(-2) (500 mu M-2 mM) and 127.2 mu M mM(-1) cm(-2) (2 mM-10 mM)), good selectivity, reproducibility (RSD=2.4%) and applicability to real sample (human serum).
