Abstract

Three recurring hypotheses are often used to explainthe effect of non-thermal plasmas (NTPs) on NTP catalytichybrid reactions;namely,modification or heating of thecatalyst or creation of new reaction pathwaysbyplasma-produced species.NTP-assisted methane (CH4)oxidation overPd/Al2O3was investigated by direct monitoring of the X-rayabsorption fine structure of the catalyst, coupled with end-of-pipe mass spectrometry.This in situ study revealed that thecatalyst did not undergo any significant structural changesunder NTP conditions.However,the NTP did lead to anincrease in the temperature of the Pd nanoparticles;althoughthis temperature rise was insufficient to activate the thermalCH4oxidation reaction. The contribution of alower activationbarrier alternative reaction pathway involving the formation ofCH3(g) from electron impact reactions is proposed.
