Electrical discharges in water for pollutant degradation have been studied intensively, but there are almost no studies on electrical discharges in organic solvents. In this study, three separate experiments are conducted in relatively polar organic solvents: diamond‐like carbon (DLC) film synthesis, ammonia production, and hydrogen generation from methanol. The synthesis of DLC is attempted by conducting electrical discharge in four different organic liquids: acetone, methanol, acetonitrile, and dimethyl sulfoxide. Ammonia production is reported from both acetonitrile/water mixtures and hydrogen and methanol in the presence of nitrogen, although higher yields are measured from acetonitrile. Hydrogen production by electrical discharge from varying methanol/water mixtures is studied and the major liquid‐ and gas‐phase byproducts of methanol decomposition are identified.
