Plasma-Modified Dendritic Cu Catalyst for CO2 Electroreduction.
TL;DR: Low-pressure oxygen plasmas are used to modify dendritic Cu catalysts and were able to achieve enhanced selectivity toward C2 and C3 products, shedding light into the strong structure/chemical state-selectivity correlation in CO2RR and open venues for the rational design of more effective catalysts through plasma pretreatments.
Journal ArticleDOI
CO2 electroreduction on copper-cobalt nanoparticles: Size and composition effect
Miguel Bernal,Alexander Bagger,Fabian Scholten,Ilya Sinev,Arno Bergmann,Mahdi Ahmadi,Mahdi Ahmadi,Jan Rossmeisl,B. Roldan Cuenya,B. Roldan Cuenya,B. Roldan Cuenya +10 more
TL;DR: In this paper, bimetallic size-selected Cu100-xCox nanoparticle (NP) catalysts for CO2 electroreduction reaction (CO2RR) were identified and the optimum Cu/Co ratio and NP size leading to improved activity and selectivity.

CO2 Electroreduction on Copper-Cobalt Nanoparticles: Size and Composition Effect
Miguel Bernal,Alexander Bagger,Fabian Scholten,Ilya Sinev,Arno Bergmann,Mahdi Ahmadi,Mahdi Ahmadi,Jan Rossmeisl,B. Roldan Cuenya,B. Roldan Cuenya,B. Roldan Cuenya +10 more
TL;DR: In this paper, bimetallic size-selected Cu100-xCox nanoparticle (NP) catalysts were used for CO2 electroreduction reaction (CO2RR) and they identified the optimum Cu/Co ratio and NP size leading to improved activity and selectivity.
Journal ArticleDOI
Piece by Piece-Electrochemical Synthesis of Individual Nanoparticles and their Performance in ORR Electrocatalysis.
TL;DR: Collisions of individual precursor-filled nanocontainers are presented as a new route to nanoparticle-modified electrodes with high catalyst utilization and show great catalyst performance for ORR (oxygen reduction reaction) already at low catalyst loadings.
Journal ArticleDOI
Reversible Water-Induced Phase Changes of Cobalt Oxide Nanoparticles.
Dennis Hein,Dennis Hein,Garlef Wartner,Garlef Wartner,Arno Bergmann,Miguel Bernal,Miguel Bernal,Beatriz Roldan Cuenya,Robert Seidel,Robert Seidel +9 more
TL;DR: The results demonstrate the appearance of water-induced structural changes different from voltage-induced changes and help to understand the atomic scale interaction of CoOx nanoparticles with water in electrochemical processes.
