Promoting H2O2 production via 2-electron oxygen reduction by coordinating partially oxidized Pd with defect carbon. [PDF]

, 2020
Electrochemical synthesis of H2O2 through a selective two-electron (2e-) oxygen reduction reaction (ORR) is an attractive alternative to the industrial anthraquinone oxidation method, as it allows decentralized H2O2 production. Herein, we report that the

Pd Nanoparticles Supported on Tungsten Carbide Embedded onto Ordered Mesoporous Carbons for Electrocatalysis of Formic Acid Oxidation

International Journal of Electrochemical Science, 2013
In this work, tungsten carbide (WC) embedded onto ordered mesoporous carbons (OMCs) is used as the support of Pd nanoparticles for electrocatalytic oxidation of formic acid. The WC loaded OMCs was prepared via a hard template route. Pd nanoparticles were

A Predictive Model for Convective Flows Induced by Surface Reactivity Contrast [PDF]

, 2017
Concentration gradients in a fluid along a reactive surface due to contrast in surface reactivity generate convective flows. These flows result from contributions by electro and diffusio osmotic phenomena. In this study we have analyzed reactive patterns

Switching on electrocatalytic activity in solid oxide cells [PDF]

Nature, 2016
Solid oxide cells (SOCs) can operate with high efficiency in two ways-as fuel cells, oxidizing a fuel to produce electricity, and as electrolysis cells, electrolysing water to produce hydrogen and oxygen gases. Ideally, SOCs should perform well, be durable and be inexpensive, but there are often competitive tensions, meaning that, for example ...

Engineering Hydrogen‐Down Water Configurations for Ampere‐Level Electrochemical CO2 Reduction to Formate

Advanced Functional Materials, EarlyView.
Electrochemical CO2 reduction (ECR) to formate is a promising route for sustainable chemical production. Herein, we report the synthesis catalysed byBi‐HfO2@C. The AIMD simulations, DFT calculations, and in situ SEIRAS measurements show that the modification of HfO2 on the Bi surface steers the interfacial water to adopt a favorable hydrogen‐down (OH2↓)
