Electrocatalysis

Electrocatalysis is a type of catalysis that results in the modification of the rate of an electrochemical reaction occurring on an electrode surface. The relative electrocatalytic properties of a group of materials at a given temperature and concentration are not necessarily constant, and may vary according to the different dependence of rates on electrical potential.

    Glucose is a promising feedstock for hydrogen production but the existing microbial reactors are expensive and suffer from low efficiencies. Here, the authors show an improved self-powered liquid catalyst fuel cell with a polymer-exchange membrane and polyoxometalate to catalyse glucose to hydrogen.

    High-entropy metallic glasses are an unexplored class of nanomaterials and are difficult to prepare. Here, the authors present an electrosynthetic method to design these materials with up to eight tunable metallic components and show multifunctional electrocatalytic water splitting capabilities.

    Capacity fading and electrochemical polarization pose barriers to the commercial use of lithium-sulfur batteries. Here the authors show improved charge polarization and electrochemical performance in a surface oxidized quantum-dot-size titanium nitride embedded within a highly ordered mesoporous carbon matrix.

    Identification of active sites is one of the main obstacles to rational design of catalysts for scientific and industrial applications. Here, the authors demonstrate the synthesis and structural identification of Zn based active sites, as well as the related structural activation for oxygen species.

    Some of the best electrocatalysts for the oxygen evolution reaction in alkaline electrolysers are based on oxides of nickel and iron. Here, the authors demonstrate that the water oxidation performance of such catalysts can be enhanced by application of a magnetic field from a permanent magnet.

    Redox flow batteries are promising for large-scale energy storage, but are hindered by cost, stability, and safety issues. Here the authors construct an all-polymer particulate slurry battery to bypass solubility limits and apply insoluble redox-active materials.
