Precise determination of the onset potentials in electrocatalytic reactions is a key challenge to understanding the reaction mechanisms and further possibilities about how to improve them. LIQUIDLOOP technology enables accurate following of the various reaction onsets during even up to 100 cycles, perfect solution for studying long term stability of the catalyst material and electrodes.Full article
Tunable saturation of electrolyte with the reactant gas defines its partial pressure in the system, allowing for design of various novel experiments with focus on thermodynamics and kinetics of the electrocatalytic reactions.
In this study, a mixture of two reactant gases CO2 and CO with precisely defined ratios was used to saturate the electrolyte for revealing the dependency between their partial pressures onto the selectivity for C2 products. Moreover, CO gas labelling using minimal amount of the precious isotop-labelled gas offered further mechanistic insights into ethylene formation pathways.Full article
