Enhanced removal of toluene by dielectric barrier discharge coupling with Cu-Ce-Zr supported ZSM-5/TiO2/Al2O3

, 2017
Toluene was removed by dielectric barrier discharge coupling with Cu-Ce-Zr supported ZSM-5/TiO2/Al2O3 catalysts. Copper cerium and zirconium species were highly dispersed on the support surface and copper was mostly in Cu2+ and Cu+ state co-existed.
