For the hydrocarbons methane through heptane, ethylene, and carbon monoxide anodic potential/current density curves were measured in a galvanostatic half‐cell arrangement. Raney platinum proved to be an active catalyst for the conversion of the hydrocarbons. In
3N H2SO4
at 100°C a stationary current density of 200 ma/cm2 was measured for ethane, propane, butane, ethylene, and carbon monoxide, and 100 ma/cm2 for methane and pentane. By coulometric analyses the conversion of methane, ethane, and propane to
CO2
was found to be 100%. Complete conversion of butane, pentane, hexane, and heptane apparently requires conditions different from those employed here. In
5N H2SO4
potential oscillations with time were observed, which were caused by partial poisoning of the electrode on reduction of
H2SO4
to
H2S
and the subsequent self‐regeneration of the electrode.
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.
