By
taking advantage of the high solubility of CO2 and
CH4 at low temperature, we report the electrochemical conversion
of these gases in aqueous media down to −40 °C. The 5-fold
increase in the concentration of CH4 in gas hydrate slurries
makes its electrochemical oxidation feasible at temperatures below
the freezing point of water. We also report the electrochemical conversion
of CO2 at low temperatures and demonstrate, unexpectedly,
that its reduction in these conditions follows an anti-Arrhenius kinetics
electrochemical environment. These findings open windows of investigation
into electrocatalysis in brines below the freezing point of water.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations –citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
