Ag nanoparticles supported on nickel foam: a flexible 3D electrode for methanol electrocatalytic oxidation

Abstract

Ag nanoparticles were prepared on nickel foam electrode coated Nafion membranes for eletrocatalytic oxidation methanol.

Electrochemically Robust Ferberite (FeWO4) Nanostructure as an Anode Material for Alkaline Water- and Alcohol-Oxidation Reaction

“…(ii) The Nafion solution was diluted by ethanol to 1.0 wt %, and 50 mg of FeWO 4 was added in 1 mL of diluted Nafion solution and perfluorosulfonated ion-exchange polymer. 68 The prepared catalyst solution was then drawn through a micropipette, deposited on an (10 × 10 mm 2 ) NF surface and dried at room temperature. The amount of catalyst loaded was calculated by the weight difference between before and after deposition.…”

“…The deposition on NF requires the following steps(i) NF was cut into 20 × 10 mm 2 pieces, sonicated in 0.1 N HCl, Milli-Q water, and acetone for 10 min each and then dried at 50 °C. (ii) The Nafion solution was diluted by ethanol to 1.0 wt %, and 50 mg of FeWO 4 was added in 1 mL of diluted Nafion solution and perfluorosulfonated ion-exchange polymer . The prepared catalyst solution was then drawn through a micropipette, deposited on an (10 × 10 mm 2 ) NF surface and dried at room temperature.…”

A Facile Molecular Approach to Amorphous Nickel Pnictides and Their Reconstruction to Crystalline Potassium‐Intercalated γ‐NiOOHx Enabling High‐Performance Electrocatalytic Water Oxidation and Selective Oxidation of 5‐Hydroxymethylfurfural

“…Herein, we first present the electrocatalytic results on NF due to its superior surface area and conductivity. [ 57 ] To rule out the effects of the electrode substrate, we reconfirmed all results on FTO. Prior to all measurements, the deposited materials were activated to reconstruct them completely into stable and active catalysts by performing cyclic voltammetry (CV) cycles in the potential range of 1.0–1.8 V (vs reversible hydrogen electrode, RHE), until stable current responses were obtained (≈20 CVs).…”

Ease of Electrochemical Arsenate Dissolution from FeAsO4 Microparticles during Alkaline Oxygen Evolution Reaction

“…At first, NF was cut into 2 × 1 cm pieces and then washed with hydrochloric acid (0.01 M) through sonication for 10 min, followed by washing with Milli-Q water and acetone and then drying at 50 °C for 8 h. The Nafion solution was diluted with ethanol to 1.0 wt %, and 50 mg FeAsO 4 was added to the 1 mL solution. 68 The resulted mixture was ultrasonicated for 10 min. The prepared catalyst ink was then drop-casted through a micro-pipette on (1 × 1 cm 2 ) NF surface.…”
