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
Mimicking Horseradish Peroxidase Functions Using Cu2+-Modified Carbon Nitride Nanoparticles or Cu2+-Modified Carbon Dots as Heterogeneous Catalysts.
Margarita Vázquez-González,Wei Ching Liao,Rémi Cazelles,Shan Wang,Xu Yu,Vitaly Gutkin,Itamar Willner +6 more
TL;DR: The concentration of dopamine, at the Cu2+-C-dots' surface, by means of the β-CD receptor sites, leads to a 4-fold enhancement in the oxidation of dopamine by H2O2 to yield aminochrome compared to that of the unmodified C-d dots.
Journal ArticleDOI
From a Molecular 2Fe-2Se Precursor to a Highly Efficient Iron Diselenide Electrocatalyst for Overall Water Splitting.
Chakadola Panda,Prashanth W. Menezes,Carsten Walter,Shenglai Yao,Matthias E. Miehlich,Vitaly Gutkin,Karsten Meyer,Matthias Driess +7 more
TL;DR: The first iron selenide material is reported that can be used as a bifunctional electrocatalyst for the OER and HER, as well as overall water splitting, which is also favorable for the HER.
Journal ArticleDOI
Boosting electrochemical water oxidation through replacement of Oh Co sites in cobalt oxide spinel with manganese
TL;DR: The strikingly high catalytic performance and stability of manganese substituted cobalt oxide spinel (MnxCo3-xO4) over pristine Cobalt oxidespinel (Co3O 4) for the alkaline electrochemical water oxidation is reported.
Journal ArticleDOI
Using nickel manganese oxide catalysts for efficient water oxidation
Prashanth W. Menezes,Arindam Indra,Ophir Levy,Kamalakannan Kailasam,Vitaly Gutkin,Johannes Pfrommer,Matthias Driess +6 more
TL;DR: Nickel-manganese oxides with variable Ni : Mn ratios, synthesised from heterobimetallic single-source precursors, turned out to be efficient water oxidation catalysts showing superior activity and remarkable stability.
