The present work describes a facile way to introduce controllable heterostructured Ni/NiS on carbon paper (Ni/NiS@CP) via one-step electrodeposition, which improves both urea electrooxidation and hydrogen evolution.
The electrooxidation of small organic compounds plays a crucial role in the production clean and efficient energy. Ethylene glycol (EG) has gained considerable interest recently due to its energy...
This work examines the cooperative effect between Zr doping and oxygen vacancy engineering in anodized TiO2 nanotubes (TNTs) for enhanced reduction reactions (ORRs). dopant annealing conditions significantly affected electrocatalytic characteristics of grown TNTs. results Zr4+ substituted Ti4+ species, which indirectly creates donors that enhance charge transfer kinetics reduce carrier recombination TNT bulk. Moreover, vacancies promote creation unsaturated Ti3+(Zr3+) sites at surface, also...
Electrooxidation of urea plays a substantial role in the elimination urea-containing wastewater and industrial urea. Here, we report electrodeposition nickel hydroxide catalyst on commercial carbon paper (CP) electrodes from dimethyl sulphoxide solvent (Ni(OH)2-DMSO/CP) for electrooxidation under alkaline conditions. The physicochemical features Ni(OH)2-DMSO/CP catalysts using scanning electron microscopy X-ray photoelectron spectroscopy revealed that shows nanoparticle features, with...
An electrocatalyst of potassium nickel aluminium hexafluoride (KNiAlF6) nanosheets has been prepared using solid-phase synthesis at 900 °C. X-ray diffraction, scanning electron microscopy, and conductivity studies confirmed the formation KNiAlF6 having a cubic defect pyrochlore structure with an average thickness 60-70 nm 1.297 × 103 S m-1. The electrochemical catalytic activity was investigated for urea oxidation in alkaline solution. results show that exhibit mass ∼395 mA cm-2 mg-1 1.65 V...
Recently the urea and urinated wastewater electrolysis process has shown promising technology for hydrogen fuel green production in addition to denitrification of wastewater. However, make economically valuable, electrocatalysts nanoarchitecture, nanometer size, shape, facets, composition need be engineered boost oxidation reaction (UOR). This work demonstrates a simple novel approach synthesis mesoporous nickel phosphate nanoparticles (meso-NiPO) via chemical deposition from surfactant...
In this present paper, a series of defect-rich iron oxy/hydroxide nanorod arrays: α-FeOOH, Fe 2 O 3 , FeO x NRs, and Co-FeO thin film catalysts were synthesized via hydrothermal approach followed by thermal vacuum treatments.
This work demonstrates the chemical synthesis of two-dimensional nanoflakes mesoporous nickel/nickel (II) hydroxide (Ni/Ni(OH)2-NFs) using double templates surfactant self-assembled thin-film and foam hydrogen bubbles produced by sodium borohydride reducing agent. Physicochemical characterizations show formation amorphous 2D with a Ni/Ni(OH)2 structure high specific surface area (165 m2/g). Electrochemical studies that electrocatalytic activity towards methanol oxidation in alkaline solution...
Abstract A series of modified starches were prepared by grafting acetylsalicylic acid (AsA) into starch an esterification reaction then coated with poly(vinylalcohol).The structure Starch-graft-AsA was confirmed FTIR, NMR, and DSC. The release AsA occurred via a retroesterification this (SAC) during 76 h at different pHs contents. diffusion coefficient in the SAC matrix followed Fickian model. effect amount grafted on revealed that higher released reached containing 16.18 mol% pH 7....
Abstract Mesoporous 2D nanoflakes architectures of mono- and bi-metallic cobalt nickel hydroxide (meso-Co-Ni(OH)2) hybrids were synthesized using novel chemical precipitation foam-surfactant liquid crystal dual template (FSDT). The dissolved ions within the aqueous region Brij®78 surfactant was reduced by excess sodium borohydride reducing agent that simultaneously generates excessive hydrogen foam as a double template. physicochemical characterizations nanostructured Co-Ni(OH)2 performed...
