Pulse Voltammetry

A novel nanocomposite of N-Doped Carbon Quantum Dots@Carbon Nanotubes was synthesized in this study for electrochemical detection of bisphenol A by differential pulse voltammetry. The nanocomposite was characterized by transmission electron microscopy, scanning electron microscopy, X-ray powder diffraction and Fourier transform infrared spectroscopy. Electrochemical properties of the nanocomposite modified glassy carbon electrodes were studied via cyclic voltammetry. Differential pulse voltammetry experimental results showed that N-Doped Carbon Quantum Dots@Carbon Nanotubes/glassy carbon electrode exhibited excellent catalysis activity towards electrochemical oxidation of bisphenol A. The oxidation peak current was linearly increased with concentration of bisphenol A in the range from 0.4 μM to 40 μM, with a limit of detection of 65 nM.

Ternary Composite

Based on various carbon nano materials, the ternary composite functionalized carbon nanotubes (FMWCNTs) @ carbon quantum dots (CQDs) @ polyaniline (PANI) was prepared by in-situ polymerization and hydrothermal method. The carbon-based material was made into an electrode sheet. The morphology and microscopic nanostructures were characterized by FTIR, field emission scanning electron microscopy and field emission transmission electron microscopy. Cyclic voltammetry and the galvanostatic charge discharge method was adapted to study the electrochemical properties of these active materials. Our results showed that the specific capacitance of FMWCNTs @ CQDs @ PANI was as high as 534 F/g, while it was 362 F/g, 319 F/g and 279 F/g for PANI @ FMWCNTs, PANI @ CQDs and polyaniline. This means that the specific capacitance of FMWCNTs @ CQDs @ PANI is increased by 47.5%, 67.4% and 91.4% comparing with the capacitance of PANI @ FMWCNTs, PANI @ CQDs and polyaniline, respectively. Moreover, the specific capacitance retention rate of the ternary active electrode after 1000 times of constant current charge and discharge cycle reached 86%, while it was 60% for PANI @ FMWCNTs, 72% for PANI @ CQDs and 65% for polyaniline.
