Enhanced performance in catalytic combustion of toluene over mesoporous Beta zeolite-supported platinum catalyst

Mesoporous Beta zeolite-supported Pt catalyst (Pt-R/Beta-H) exhibits much higher catalytic activities and longer catalyst life as well as lower apparent activation energy in combustion of toluene than conventional Beta zeolite-supported Pt catalyst (Pt-R/Beta). This phenomenon could be strongly related to the presence of mesoporosity in Beta-H zeolite, which is favorable for mass transfer and dispersion of Pt particles.
