Radio-frequency-powered atmospheric pressure plasma jet for the destruction of binary mixture of naphthalene and n-butanol with Pt/Al 2 O 3 catalyst

•Destruction of naphthalene and n-butanol by an rf-powered atmospheric pressure plasma jet (APPJ) and catalytic APPJ (CAPPJ) has been investigated.•In the presence of Pt/Al2O3 catalyst with SV of 17,4001/h, XNap and Xn-b can reach as high as 99%.•Kinetics was predicted satisfactorily by reaction order of −1.5 and 1 for the APPJ and CAPPJ.•The information obtained is useful for operation, design, and analysis of plasma devices.
