Electron transfer mechanisms of biphenyl sorption in M-ZSM-5 (M=H+, Cu2+) zeolites
Abstract
The sorption of biphenyl (BP) in dehydrated M-ZSM-5 (M=H+, Cu2+) zeolites through solid–gas exchange spontaneously causes ionisation of BP molecules; the radical cation and trapped electron disappear slowly via two different electron transfer mechanisms.
