A carbon quantum dot (CQD)/reduced graphene oxide (rGO) nanocomposite modified glassy carbon electrode (GCE) was developed as a novel system for electrochemical detection of cadmium ion (Cd). The characterization of the synthesized CQD/rGO nanocomposite was done by Fourier transform infrared, high-resolution transmission electron microscopy, Raman, ultraviolet–visible, and X-ray diffraction analys...... hiện toàn bộ
Chemisorption-Isotherm Measurements at Electrode Surfaces by Quantitative High-Resolution Electron Energy Loss SpectroscopyElectrocatalysis - Tập 4 - Trang 101-103 - 2013

The chemisorption isotherm of benzoquinone at a well-defined Pd(100) surface was obtained by quantitative high-resolution electron energy loss spectroscopy (HREELS). Extraction of surface-coverage information from HREELS required the normalization of integrated peak intensities to compensate for differences in the backscattered electron flux brought about by the organic adlayer. A common procedure...... hiện toàn bộ
Influence on the Electrocatalytic Water Oxidation of M2+/M3+ Cation Arrangement in NiFe LDH: Experimental and Theoretical DFT EvidencesElectrocatalysis - Tập 8 - Trang 383-391 - 2017

This contribution reports the effect of the iron content and M2+/M3+ ratio cation arrangement-distribution on the oxygen evolution reaction (OER) catalyzed by layered double hydroxides. The electrocatalysts, containing variable contents of Ni and Fe, were successfully prepared through a homogeneous precipitation method. The formation of LDH structure was verified by powder X-ray diffraction (XRD) ...... hiện toàn bộ

Efficient and low-cost electrocatalyst materials are highly in demand for energy generation from small organic materials. Herein, we developed polyaniline (PANI)/reduced graphene oxide (rGO) (PANI/rGO) as an efficient and low-cost electrocatalyst support material to improve the efficiency of nickel phosphide (NiP) for alkaline urea oxidation via a combination of facile solvothermal method and simp...... hiện toàn bộ
Electroanalysis of Cd2+ and Pb2+ Based on Bi/Fe3O4/RTIL ElectrodeElectrocatalysis - Tập 12 - Trang 381-389 - 2021
Jiao Zhou, Qi Wang, Fanglin Liu, Shiquan Xiong
Bi-based electrodes for detection of Cd2+ and Pb2+ have been widely reported; however, few were reported about the electroanalysis of Cd2+ and Pb2+ by variation of electrode materials in fixed Bi3+ concentration. Herein, two types of Fe3O4 with large size (400–500 nm) of Fe3O4 (LFe3O4), small diameter (40–60 nm) of Fe3O4 (SFe3O4) synthesized by two methods, and Fe3O4/RTIL (room temperature ion liq...... hiện toàn bộ
