Water electrolysis using carbon electrodes can lead to the formation of methane alongside hydrogen. The process involves the carbon cathode facilitating hydrogen production, while also potentially allowing hydrogen to bond with carbon, resulting in methane and possibly other hydrocarbon chains. Observations indicate minimal oxygen liberation and the production of CO2, which dissolves in the solution. This suggests a complex interaction between the carbon electrode and the electrolysis process.
PREREQUISITESChemists, materials scientists, and researchers interested in alternative energy sources and hydrocarbon synthesis through electrolysis.
There is very little oxygen liberated, and there seems to be CO2 produced which immediately dissolves.johnbbahm said:I was wondering if I breakdown water with a carbon electrodes,
will some methane be formed as well as hydrogen?
In addition if methane is formed could other hydrocarbon chains also occur?
