Driven by the serious ecological problems, it is urgent to explore high-efficiency sustainable energy technologies. Oxygen electrocatalysis acts as important half-reactions in emerging electrochemical techniques including electrolysis and batteries. Gel composites exhibit merits of rich porous, superior hydrophilic, large specific surface area, which can significantly improve electrolyte penetr...

Understanding electrified interfaces is crucial to enabling a multitude of applications, including photo(electrocatalysis), supercapacitors, pseudocapacitors and batteries. However, reaching an atomistic understanding remains challenging will require the combination development refined computations experiments.

In work related to the electrocatalysis of the CO2 reduction reactions, we recently reported in This Journal the structure and composition of a Cu(100) electrode surface, pre-dosed at low levels of O2(g) to simulate a Cu electrocatalyst unprotected from air, before and after immersion in alkaline electrolyte at fairly negative potentials to ascertain if an oxide-to-metal reduction reaction can ...
