The production of H2O2 in the microwave discharge plasma of CH4/O-2

Unexpectedly, the product analysis in microwave CH4/O-2 discharge by Li+ io n attachment mass spectrometry has brought forth a detection in the formati on of the hydrogen peroxide H2O2. Furthermore, the observation of the minor H2O2H+ peak gives indirect evidence of H2O2 formation. The studies have be en done in terms of discharge conditions with a view of increasing the prod uct rate and to confirm the possible production of this compound in the gas phase.
