High-valence metals improve oxygen evolution reaction performance by modulating 3dmetal oxidation cycle energetics

Likai Zheng, Yang Li, Yelin Hu, Jun Li, Ye Zhang, Ziyun Wang, Bo Zhang, Zhen Cao

Multimetal oxyhydroxides have recently been reported that outperform noble metal catalysts for oxygen evolution reaction (OER). In such 3d-metal-based catalysts, the oxidation cycle of 3dmetals has been posited to act as the OER thermodynamic-limiting proc ...

The Effect of Surface Reconstruction on the Oxygen Reduction Reaction Properties of LaMnO3

Vasiliki Tileli, Reinis Ignatans

Perovskites have been widely studied for electrocatalysis due to the exceptional activity they exhibit for surface-mediated redox reactions. To date, descriptors based on density functional theory calculations or experimental measurements have assumed a bu ...

A catalytically active [Mn]-hydrogenase incorporating a non-native metal cofactor

Xile Hu, Farzaneh Fadaei Tirani, Matthew Wodrich, Huijie Pan

Nature carefully selects specific metal ions for incorporation into the enzymes that catalyse the chemical reactions necessary for life. Hydrogenases, enzymes that activate molecular H-2, exclusively utilize Ni and Fe in [NiFe]-, [FeFe]- and [Fe]-hydrogean ...

Formal Aza-Wacker Cyclization by Tandem Electrochemical Oxidation and Copper Catalysis

Xile Hu, Xiangli Yi

In oxidative electrochemical organic synthesis, radical intermediates are often oxidized to cations on the way to final product formation. Herein, we describe an approach to transform electrochemically generated organic radical intermediates into neutral p ...

Impact of cation redox chemistry on continuous hydrothermal synthesis of 2D-Ni(Co/Fe) hydroxides

Andreas Stephan Lesch, Massimo Rosa

Continuous hydrothermal flow synthesis (CHFS) is a facile, upscalable and cost-efficient synthetic method enabling the nanostructuring of advanced functional materials in steady conditions, i.e. not in batch synthesis. In this paper, we use CHFS to crystal ...

Design of Surface-Supported Bio-inspired Networks for CO2 and O2 Activation at Room Temperature

Daniel Eduardo Hurtado Salinas

The structure of a biological system defines its function. Therefore, nature has developed sophisticated systems that catalyze chemical reactions that are vital for life on earth. For instance, the photosynthesis is a biological process that is partially r ...
