The electroreduction of CO2 plays an important role in achieving a net-zero carbon economy. Imidazolium cations can be used to enhance the rate of CO2 reduction reactions, but the origin of this promotion remains poorly understood. In this work, we show that in the presence of 1-ethyl-3-methylimidazolium (EMIM+), CO2 reduction on Ag electrodes occurs with an apparent …

Sodium metal batteries have attracted increasing interest recently, but suffer from severe dendrite growth caused by uneven Na plating/stripping behavior, which may result in the piercing of the membrane, with short circuiting and even cause explosions. Herein, a conductive and sodiophilic Ag coating layer i
The electrocatalytic conversion of waste nitrate (NO3–) into value-added ammonia (NH3) is a promising water treatment approach to remedy environmental pollution. However, developing catalyst design and optimization strategies to control the reaction selectivity remains a challenge. We report on an underexplored approach to overcome this challenge by tuning the …

Electrochemical cells. A typical electrochemical cell for EIS measurements on coated metals consists of a cylinder that contains the solution, the reference electrode (SCE, Ag/AgCl, etc.) and the counter-electrode, which can be a Pt, Ni or Ti grid. The cell is usually clamped on the metallic sample that acts as the working electrode. However, variations of this configuration have been …
