Electrodeposition of ternary CuNiPt alloy nanoparticles on graphenized pencil lead electrode as a new electrocatalyst for electro-oxidation of ethanol

Hydrothermal Synthesis of MnWO4@GO Composite as Non-Precious Electrocatalyst for Urea Oxidation

“…To obtain more information on the kinetics reaction of UOR, the linear fit analysis was carried out for the anodic peak current densities of the electrocatalysts; its results are shown in Figure S5 . The results suggest that the current densities increased linearly with an increase in the scan rate and that the UOR reaction process of all electrocatalysts was controlled by the diffusion-control process [ 41 , 42 ]. Electrochemical impedance spectroscopy (EIS) plays a vital role in understanding kinetic processes in electrochemical studies.…”

Highly dispersed Pd nanoparticles on NiO–CuO nanocomposite for efficient ethanol sensing

“…18 Recently, various approaches have been developed to improve catalytic materials to enhance the electron transfer reaction at low potential. This includes Schiff base complex, 19 metal alloys/ metal nanoparticles, 3,[20][21][22][23][24][25][26] nanocomposites, [27][28][29] polymers, 30 biomolecules, 11 and metal oxides. 31 Among all these catalysts, the metal oxides and their nanocomposites came into spotlight owing to their low band gap, non-toxicity, cost-effectiveness, high chemical stability, easy availability, and good electrical conductivity.…”

Softwood Kraft Pulp-Derived Carbon-Supported PtNi Catalysts for the Electrooxidation of Ethanol

“…Whereas Comignani et al found that nickel oxide species facilitate the cleavage of the C-H and O-H bonds of ethanol both through the bifunctional mechanism and the ligand effect (Comignani et al, 2015). Habibi and coworkers studied the effect of Ni on PtNi nanoparticles supported on carbon-ceramic (Habibi and Dadashpour, 2013) and CuNiPt nanoparticles supported on graphitized pencil lead (Imanzadeh and Habibi, 2020) and suggested that the enhanced performance of the catalysts for the electrooxidation of ethanol is explained in terms of the bifunctional mechanism, the electronic effects and the augment in electroactive surface area due to the '"leaching out"' effect of the alloying element.…”
