Novel Carbon Quantum Dotted Reduced Graphene Oxide Nanosheets for Nano-molar Range Cadmium Quantification
Electrocatalysis - Tập 13 - Trang 435-446 - 2022
BarsanaBarvin RasulKhan, Sathish Kumar Ponnaiah, Jeyaprabha Balasubramanian, Prakash Periakaruppan
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 Spectroscopy
Electrocatalysis - Tập 4 - Trang 101-103 - 2013
Jean Sanabria-Chinchilla, Xiaole Chen, Ding Li, Manuel P. Soriaga
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 Evidences
Electrocatalysis - Tập 8 - Trang 383-391 - 2017
Ariel Guzmán-Vargas, Juvencio Vazquez-Samperio, Miguel A. Oliver-Tolentino, Guadalupe Ramos-Sánchez, Jorge L. Flores-Moreno, Edilso Reguera
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
Co3O4 Nanorods—Efficient Non-noble Metal Electrocatalyst for Oxygen Evolution at Neutral pH

Vacancy-Assisted Fast Electron Transport Non-noble Metal Electrocatalyst Mn0.09-MoS2 for Hydrogen Evolution Reaction
Electrocatalysis - Tập 13 - Trang 807-817 - 2022
Zhaojun Cao, Haonan Song, Chunxiang Liu, Wenjun Tang, Jing Liu, Bo Yang, Wenhui Xie, Zebin Yu
Developing the electrocatalyst with low cost, high efficiency, and environmentally friendly for hydrogen evolution reaction (HER) is important for the goal of high conversion of sustainable energy resources. Herein, a transition metal electrocatalyst named as Mn0.09-MoS2 is designed via a facile route. The successful substituting of Mn allows partial Mo in the original sulfide replaced by Mn and f...... hiện toàn bộ
Insights into the Electrochemical Behavior and Kinetics of NiP@PANI/rGO as a High-Performance Electrode for Alkaline Urea Oxidation
Electrocatalysis - Tập 13 - Trang 283-298 - 2022
Israel Leka Lera, Sutripto Khasnabis, Lodrick Makokha Wangatia, Femi Emmanuel Olu, Praveen C. Ramamurthy
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
Catalytic Performance Comparison of Shape-Dependent Nanocrystals and Oriented Ultrathin Films of Pt4Cu Alloy in the Formic Acid Oxidation Process

Fook Yun Ban, Subramaniam Jayabal, Alagarsamy Pandikumar, Hong Ngee Lim, Nay Ming Huang
The reduced graphene oxide/multiwalled carbon nanotubes deposited on nickel foam (rGO/MWCNTs/NF) composite material was successfully prepared using one-pot hydrothermal method. The prepared rGO/MWCNTs/NF composite material was characterized using scanning electron microscopy, electron dispersive spectroscopy, and Raman spectroscopy. The results show that MWCNTs were successfully incorporated into ...... hiện toàn bộ
Electroanalysis of Cd2+ and Pb2+ Based on Bi/Fe3O4/RTIL Electrode
Electrocatalysis - 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
