Journal ArticleDOI
Unification of catalytic water oxidation and oxygen reduction reactions: amorphous beat crystalline cobalt iron oxides.
Arindam Indra,Prashanth W. Menezes,Nastaran Ranjbar Sahraie,Arno Bergmann,Chittaranjan Das,Massimo Tallarida,Dieter Schmeißer,Peter Strasser,Peter Strasser,Matthias Driess +9 more
TL;DR: This work presents a facile solvothermal route to control the synthesis of amorphous and crystalline cobalt iron oxides by controlling the crystallinity of the materials with changing solvent and reaction time and utilizes these materials as multifunctional catalysts for the unification of photochemical and electrochemical water oxidation as well as for the oxygen reduction reaction.
Journal ArticleDOI
Uncovering the Nature of Active Species of Nickel Phosphide Catalysts in High-Performance Electrochemical Overall Water Splitting
Prashanth W. Menezes,Arindam Indra,Chittaranjan Das,Carsten Walter,Caren Göbel,Vitaly Gutkin,Dieter Schmeiβer,Matthias Driess +7 more
TL;DR: A systematic structural elucidation of the near surface active species of the two remarkably active nickel phosphides Ni12P5 and Ni2P on the basis of extensive analytical, microscopic, and spectroscopic investigations is reported in this paper.
Journal ArticleDOI
Boosting Visible-Light-Driven Photocatalytic Hydrogen Evolution with an Integrated Nickel Phosphide–Carbon Nitride System
Arindam Indra,Amitava Acharjya,Prashanth W. Menezes,Christoph Merschjann,Dirk Hollmann,Michael Schwarze,Mesut Aktas,Aleksej Friedrich,Stefan Lochbrunner,Arne Thomas,Matthias Driess +10 more
TL;DR: The synthesis of a sol-gel prepared mesoporous graphitic carbon nitride combined with nickel phosphide (Ni2 P) which acts as a superior co-catalyst for efficient photocatalytic H2 evolution by visible light is reported.
Journal ArticleDOI
Active Mixed‐Valent MnOx Water Oxidation Catalysts through Partial Oxidation (Corrosion) of Nanostructured MnO Particles
Arindam Indra,Prashanth W. Menezes,Ivelina Zaharieva,Elham Baktash,Johannes Pfrommer,Michael Schwarze,Holger Dau,Matthias Driess +7 more
TL;DR: Mixed-valent amorphous MnOx catalysts suitable for photochemical and electrochemical water oxidation are prepared by treatment of nanostructured catalytically inactive MnO precursors with (NH4)2Ce(NO3)6 solution for 15 min under vigorous stirring as discussed by the authors.
Journal ArticleDOI
High-Performance Oxygen Redox Catalysis with Multifunctional Cobalt Oxide Nanochains: Morphology-Dependent Activity
Prashanth W. Menezes,Arindam Indra,Diego González-Flores,Nastaran Ranjbar Sahraie,Ivelina Zaharieva,Michael Schwarze,Peter Strasser,Peter Strasser,Holger Dau,Matthias Driess +9 more
TL;DR: In this article, the authors report cobalt oxide nanochains as multifunctional catalysts for the electrochemical oxygen evolution reaction (OER) at both alkaline and neutral pH, oxidant-driven, photochemical water oxidation in various pH, and the Electrochemical oxygen reduction reaction (ORR) in alkaline medium.
