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.

    Platinum plays a crucial role in various electrocatalytic systems, but its scarcity and cost limit its practical application. Now, a single-atom tailoring strategy applied to platinum nanowires maximizes their specific and mass activities for the hydrogen evolution and methanol and ethanol oxidation reactions.

    Catalytic oxygen reduction is an important process for clean energy production. Here the catalytic activity of trioxotriangulenes for the oxygen reduction reaction is shown to be correlated with their redox potential, offering a potential route to rationally tune their catalytic activity.

    Electrocatalytic water splitting for hydrogen and oxygen generation provides an attractive path to obtain clean energy, but the half reaction of oxygen evolution remains the bottleneck for the progress. Here, the authors show single atom tungsten doped ultrathin α-Ni(OH)2 exhibits enhanced performance in electrocatalytic water oxidation.

    Electrochemical water splitting in acidic conditions is limited by the lack of inexpensive and stable anode catalysts. Now, Simonov and colleagues report a non-noble metal-based oxygen evolution catalyst formed in situ that exhibits high stability for acidic water oxidation due to a self-healing mechanism.

    While water splitting may afford a renewable means to store energy in chemical bonds, water oxidation catalysts suffer from poor stabilities in acidic media. Here, authors show sodium doping of strontium ruthenate to improve the catalytic durability while maintaining a high O2 evolution activity.

    Water oxidation catalysts are key components in water-splitting devices that synthesize fuels by using energy, including that from sunlight. This Perspective presents historical developments in molecular water oxidation catalysis, emphasizing studies of ruthenium complexes that have taught us how to design optimal catalysts.
