Report

What X-ray absorption spectroscopy can tell us about the active state of earth-abundant electrocatalysts for the oxygen evolution reaction

Autor: Risch, Marcel, Morales, Dulce M., Villalobos, Javier, Antipin, Denis

Chemical energy storage is an attractive solution to secure a sustainable energy supply. It requires an electrocatalyst to be implemented efficiently. In order to rationally improve the electrocatalyst materials and thereby the reaction efficiency, o

Report

Stabilization of Co oxide during oxygen evolution in alkaline media by the introduction of Mn oxide

Autor: Villalobos, Javier, Morales, Dulce M., Antipin, Denis, Schuck, Götz, Golnak, Ronny, Xiao, Jie, Risch, Marcel

Improving the stability of electrocatalysts for the oxygen evolution reaction (OER) through materials design has received less attention than improving their catalytic activity. We explored the effect of Mn addition to a cobalt oxide for stabilizing

Requirements for beneficial electrochemical restructuring: A model study on a cobalt oxide in selected electrolytes

Autor: Villalobos, Javier, González-Flores, Diego, Urcuyo, Roberto, Montero, Mavis L., Schuck, Götz, Beyer, Paul, Risch, Marcel

The requirements for beneficial materials restructuring into a higher performance OER electrocatalyst are still a largely open question. Here we use Erythrite (Co$_3$(AsO$_4$)$_2\cdot$8H$_2$O) as a Co-based OER electrocatalyst to evaluate its catalyt

Report

Nafion-induced reduction of manganese and its impact on the electrocatalytic properties of a highly active MnFeNi oxide for bifunctional oxygen conversion

Autor: Morales, Dulce M., Villalobos, Javier, Kazakova, Mariya A., Xiao, Jie, Risch, Marcel

Electrocatalysts for bifunctional oxygen reduction (ORR) and oxygen evolution reaction (OER) are commonly studied under hydrodynamic conditions, rendering the use of binders necessary to ensure the mechanical stability of the electrode films. The pre

Report

Reversible and irreversible processes during cyclic voltammetry of an electrodeposited manganese oxide as catalyst for the oxygen evolution reaction

Autor: Villalobos, Javier, Golnak, Ronny, Xi, Lifei, Schuck, Götz, Risch, Marcel

Publikováno v: J. Phys. Energy 2 (2020) 034009

Manganese oxides have received much attention over the years among the wide range of electrocatalysts for the oxygen evolution reaction (OER) due to their low toxicity, high abundance and rich redox chemistry. While many previous studies focused on t
