Low-temperature CO2 electrolysis is increasingly attractive for the production of sustainable electrofuels and electrochemicals as intensified research keeps pushing performance higher. Recent efforts on system engineering now offer solutions to downstream purification challenges, taking this technology one step closer to maturity.
Studying the kinetics of high-energy and high-power batteries is a formidable challenge. Now, it has been shown that redox-mediated (RM) catalysis in Li–O2 and Li–S batteries can be controlled by tuning parameters such as Li-ion concentration or electrolyte solvent, revealing threshold potentials in which rate constants increase several-fold.
Solid catalysts often exhibit a dynamic behaviour when exposed to reactive environments. Now, a study showcases how such behaviour can be exploited to maximize activity.
