Probing the role of a non-thermal plasma (NTP) in the hybrid NTP catalytic oxidation of methane [PDF]

, 2017
Three recurring hypotheses are often used to explain the effect of non-thermal plasmas (NTPs) on NTP catalytic hybrid reactions; namely, modification or heating of the catalyst or creation of new reaction pathways by plasma-produced species. NTP-assisted
