Electrochemical ammonia oxidation reaction, when coupled with hydrogen evolution reaction, offers an energy-saving anodic alternative to the oxygen evolution reaction. However, practical implementation is limited by sluggish multistep kinetics and...
Ammonia electrolysis is an attractive pathway for low energy hydrogen production because its theoretical cell voltage is substantially lower than that of conventional water electrolysis.
RuO 2 is highly active for acidic oxygen evolution in proton exchange membrane water electrolysis (PEMWE); but it dissolves and degrades under severe anodic circumstances due to lattice oxygen instability and Ru over-oxidation.
The oxygen evolution reaction (OER) is the key bottleneck in photoelectrochemical water splitting. Transition metal oxides, such as TiO2, have been used as OER catalysts in photo-electrochemical water splitting. Experiments...
The rational development of efficient and durable electrocatalysts for alkaline oxygen evolution reaction (OER) is indispensable for the advancement of next-generation energy-conversion and energy-storage technologies. Herein, a slow-growth kinetics favoured...
This review summarizes advances in Ce-modified electrocatalysts for hydrogen evolution, highlighting the roles of oxygen vacancies, Ce 3+ /Ce 4+ redox chemistry, and interfacial coupling in improving catalytic activity and stability.
The usage of gas diffusion electrode (GDE) effectively meets the industrial demand for high current densities in electrochemical CO2 reduction reaction (CO2RR). However, GDE flooding caused by electrowetting severely degrades...
