Au Nanoparticles and Graphene Quantum Dots Co-modified Glassy Carbon Electrode for Catechol Sensing Original Research Article Chemical Physics Letters, Available online 28 January 2016, Pages Xuan Zhao, Dawei He, Yongsheng Wang, Yin Hu, Chen Fu
Graphical abstractThe Au-GQDs were applied to the modification of GCE for detection of catechol. The synergist material effectively improved the electronic and catalytic properties of GCE. As a result, the catechol were effectively detected with the new sensing platform. This method is promising for the detection of catechol in environmental monitoring and safety assessment. Figure. (a) Cyclic voltammograms of 50 uM catechol at Au-GQDs/GCE with different scan rates. (b) The peak current at 0.237V of catechol vs. the sqrt of scan rate. (c) Differential pulse voltammograms of different concentrations of catechol at Au-GQDs modified GCE. The pulse period: 0.2 s, amplitude: 50mV. (d) The calibration curve between concentration and the current of peak based on DPV.

Graphical abstractIn graphene devices supported on ZnO film, ZnO layer behave as an electron donor. UV illumination experiment on hybrid graphene-ZnO device reveals that the effect of doping from ZnO becomes dominant when ZnO stripe length made larger than that of the graphene channel.
