Preparation of Nitrate Bilayer Membrane Ion-Selective Electrode Modified by Pericarpium Granati-Derived Biochar and Its Application in Practical Samples
Electrocatalysis - Tập 14 - Trang 534-545 - 2023
Fozia, Guangyao Zhao, Yanhong Nie, Jianrong Jiang, Qian Chen, Chaogang Wang, Xu Xu, Ming Ying, Zhangli Hu, Hong Xu
In this study, a pericarpium granati-derived biochar with phosphoric acid activation (PGCP) was prepared, characterized, and applied together with polypyrrole (PPy) to modify a glass carbon electrode (GCE) to construct a bilayer membrane nitrate ion-selective electrode (ISE, PPy/PGCP/GCE). The morphological results showed that PGCP possessed a porous structures. X-ray photoelectron spectroscopy an... hiện toàn bộ
Understanding the Influence of the Biomass-Derived Alcohols on the Activity and Stability of Pt Nanoparticles Supported on Graphene Nanoribbons
Electrocatalysis - Tập 8 - Trang 151-163 - 2017
Rodrigo Teles, Ana Arenillas, Gabriel C. da Silva, Pablo S. Fernández, Eduardo S. F. Cardoso, Gilberto Maia, Cauê A. Martins
We produced Pt/GNRs by a one-step synthesis procedure and evaluated their electroactivity and stability towards glycerol electrooxidation reaction (GEOR) for the first time. We compared the electrocatalytic performance of GEOR with methanol and ethanol electrooxidation on Pt/GNRs at identical experimental conditions. The activities and stabilities for the electrooxidation of these biomass-derived ... hiện toàn bộ
Functionalized Carbon Nanotubes for Highly Active and Metal-Free Electrocatalysts in Hydrogen Evolution Reaction
Electrocatalysis - Tập 9 - Trang 573-581 - 2018
Tianhao Li, Daomei Tang, Zehua Cui, Bo Cai, Dalin Li, Qianyuan Chen, ChangMing Li
Six kinds of functionalized multiwalled carbon nanotubes (FCNTs) with different functional moieties were utilized as metal-free electrocatalysts towards the hydrogen evolution reaction for the first time. Ethylenediamine-functionalized multiwalled carbon nanotubes (EDA-CNTs) delivered the best HER activity holding a low-onset overpotential of 150 mV, a Tafel slope of 116 mV dec−1, and a Faradaic e... hiện toàn bộ
Electrocatalytic Determination of Hg(II) by the Modified Carbon Paste Electrode with Sn(IV)-Clinoptilolite Nanoparticles
Electrocatalysis - Tập 10 - Trang 466-476 - 2019
Tahmineh Tamiji, Alireza Nezamzadeh-Ejhieh
In this work, the electro-reduction of Hg(II) was studied by the modified carbon paste electrode (CPE) with clinoptilolite nanoparticles (CNP) ion exchanged with Sn(IV) cations (Sn(IV)-CNP/CPE). When the Sn(IV)-CNP/CPE electrode was immersed in HCl as supporting electrolyte, the voltammetric peak currents were observed for Sn(IV)/Sn(II) redox reactions in cyclic voltammetry. The reduction peak cur... hiện toàn bộ
The Synthesis of Metallic β-Sn Nanostructures for Use as a Novel Pt Catalyst Support and Evaluation of Their Activity Toward Methanol Electrooxidation
Electrocatalysis - Tập 6 - Trang 554-562 - 2015
Olga Krichevski, Hanan Teller, Palaniappan Subramanian, Alex Schechter
This study offers a unique insight into the use of high surface area metallic tin as support material for platinum catalysts for fuel cell application. We have synthesized high surface area metallic β-tin nanostructures (TNSs) in aqueous solutions by novel one-pot process and used it as a platinum catalyst support in methanol electrooxidation reaction. Rigorous study of parameters controlling the ... hiện toàn bộ

The “Particle Proximity Effect” in Three Dimensions: a Case Study on Vulcan XC 72R
Electrocatalysis - Tập 7 - Trang 249-261 - 2016
Sebastian Proch, Kensaku Kodama, Masanori Inaba, Keiichiro Oishi, Naoko Takahashi, Yu Morimoto
The “particle proximity effect” is a hypothesis claiming that Pt nanoparticles have higher ORR activity when they get closer to one another. In order to put this hypothesis under scrutiny, the “tool-box” approach was investigated in each process step by electron microscopy, ICP, and surface science methods. It is shown that particle size stability is brought about by a NaCl shell which can effecti... hiện toàn bộ
A Novel Fe and Cu Bimetallic Mixed Porous Carbon Material for Oxygen Reduction

Electrochemical Deposited Amorphous Bimetallic Nickle-Iron (Oxy)hydroxides Electrocatalysts for Highly Efficient Oxygen Evolution Reaction
Electrocatalysis - Tập 14 - Trang 429-436 - 2022
Zhichao Xu, Jianmin Wang, Jiajia Cai, Yitao He, Jing Hu, Haijin Li, Yongtao Li, Yong Zhou
The low-cost and high-performance electrocatalysts, especially metal (oxy)hydroxides, for the oxygen evolution reaction (OER) have attracted considerable attention due to their promising OER activity. Amorphous electrocatalysts are often superior to their crystalline counterparts due to their more actives and structural flexibility. However, using traditional preparation techniques still presents ... hiện toàn bộ
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
