Desolvated cations promote CO 2 electroreduction through partial covalent interactions
Abstract Cations play a critical role in electrochemical CO2 reduction, yet the mechanisms underlying their influence remain incompletely understood owing to limited knowledge of their solvation structures and interfacial interactions under operating conditions.
Pt Particles on a Dynamic TiO2 Support in Near-Ambient Conditions–Disentangling Size, Pressure, and Support Effects
1. Introduction Click to copy section linkSection link copied! Oxide-supported platinum particles feature among the most ubiquitous catalytic systems, most prominently in three-way automotive catalysts, where they are key to oxidizing CO and NOx. Understanding and thereby gaining the ability to improve such catalysts is a common goal, and has led to various attempts at elucidating the oxidation state of these Pt particles under working conditions.
Formation of hydrided Pt-Ce-H sites in efficient, selective oxidation catalysts
Abstract Single-atom site catalysts can improve the rates and selectivity of many catalytic reactions. We have modified Pt1/CeO2 single sites by combining them with molecular groups and with oxygen vacancies of the support.
Atomic Insights into the Competitive Edge of Nanosheets Splitting Water
Introduction Click to copy section linkSection link copied! Proton exchange membrane (PEM) electrolyzers can produce green hydrogen dynamically at high purity and pressure. (1−3) These benefits make them increasingly popular to produce green hydrogen on demand, but PEM electrolyzers cannot fuel a hydrogen economy of scale because of scarce catalyst materials for the oxygen evolution reaction (OER)─one half-reaction of water electrolysis.
Unveiling Highly Sensitive Active Site in Atomically Dispersed Gold Catalysts for Enhanced Ethanol Dehydrogenation
Conflict of interests The authors declare no conflict of interest. Supporting Information As a service to our authors and readers, this journal provides supporting information supplied by the authors. Such materials are peer reviewed and may be re-organized for online delivery, but are not copy-edited or typeset. Technical support issues arising from supporting information (other than missing files) should be addressed to the authors.
Evolution of surface and sub-surface morphology and chemical state of exsolved Ni nanoparticles
Evolution of surface and sub-surface morphology and chemical state of exsolved Ni nanoparticles† Heath Kersell, *a Moritz L. Weber, bc Lorenz Falling,a Qiyang Lu,‡a Christoph Baeumer, d Nozomi Shirato,e Volker Rose,ef Christian Lenser, c Felix Gunkel b and Slavomír Nemšák *a Abstract Nanoparticle formation by dopant exsolution (migration) from bulk host lattices is a promising approach to generate highly stable nanoparticles with tunable size, shape, and distribution.
