Mechanistic Understanding of Nickel Catalyzed Urea Oxidation Reaction to Cyanate and Nitrite

Exploration, EarlyView.
The urea oxidation reaction (UOR) is a promising alternative to oxygen evolution reaction (OER) for energy efficient hydrogen production, yet its reaction mechanism remains controversial because many proposed pathways have not been directly correlated with experimentally verified products and intermediates.

Enhanced Performance of Gold Nanoparticle-Modified Nickel–Iron Coatings for Sodium Borohydride Electrooxidation

Crystals
The Ni-Fe coatings modified with AuNPs were deposited on the flexible copper-coated polyimide (Cu/PI) surface using electroless metal plating, while the galvanic displacement technique was applied to modify the surface of NiFe coatings by a small content

Molecular‐Level Engineered Approach Induces Built‐in Electric Field Modulation in G‐C3N4/CoMoS2 Heterojunction for Enhanced Hydrogen Generation via Urea Oxidation

Small, EarlyView.
Urea‐assisted electrolysis is demonstrated as an energy‐efficient route for hydrogen production by replacing the sluggish oxygen evolution reaction with kinetically favorable urea oxidation. An intrinsic electric‐field‐driven g‐C3N4/CoMoS2 heterojunction induces directional charge redistribution, promotes selective urea activation, and accelerates C─N ...

Development of Au Promoted Pd/C Electrocatalysts for Methanol, Ethanol and Isopropanol Oxidation in Alkaline Medium

International Journal of Electrochemical Science, 2012
This research is aimed to investigate the Pt-free catalysts for alcohol electrooxidation in alkaline media. The results show that Pd is a good electrocatalyst for ethanol and isopropanol oxidation. The E-TEK Pt/C shows a much higher activity for methanol

Synthesis of Patchy Particles at Phase Boundaries

Small Methods, EarlyView.
The various strategies employed for synthesizing complex multifunctional patchy particles are reviewed, with, as a guideline, the type of phase boundary (solid‐gas, liquid‐gas, solid‐liquid, and liquid‐liquid), that serves as the crucial ingredient for symmetry breaking.

Electrochemical decolorization of acid dye baths and their reuse potential in subsequent textile dyeing processes

Coloration Technology, EarlyView.
Abstract This study investigates the electrochemical decolorization of waste acid dye baths and evaluates their potential reuse in subsequent textile dyeing processes. Four different anode materials (iron, aluminum, stainless steel and graphite) were examined to optimize color removal efficiency and assess the influence of electrochemically generated ...
