Electrocatalysts enable the efficient interconversion of electrical and chemical energy for the sustainable production of fuels and chemicals. Here we highlight the importance of developing electrochemical adsorption isotherms to demystify complex reaction mechanisms and rationalize catalytic activity.
Isotope labelling with 13C-carbon has become a popular technique used to understand carbon dioxide electroreduction mechanisms. However, isotopes of carbon exhibit complex selectivity effects, which need to be carefully considered in the experimental design to avoid misinterpretations.
