Room-Temperature Electrocatalytic Dehydrogenation and Partial Fragmentation of <i>n</i>-Alkanes.

ABSTRACT: Light alkenes are central building blocks in the chemical industry, yet their production from alkanes requires energy-intensive processes that generate substantial CO₂ emissions and suffer from catalyst deactivation and overoxidation. In this work, we demonstrate that alkane dehydrogenation can be accomplished at ambient temperature and pressure by modulating the voltage applied to an electrocatalyst surface. Voltage manipulation provides real-time control over the adsorption and dehydrogenation of alkanes, as well as the potential-driven desorption of dehydrogenated adsorbates. By using a newly developed sensitive gas chromatographic (GC) analysis method, we were able to quantify the formation of 1-butene from n-butane, as well as the formation of a distribution of short
