The development of porosity in ZSM-5 zeolite by desilication in alkaline medium has been studied. Treatment of ZSM-5 in NaOH solutions leads to mesoporosity development, stemming from the preferential extraction of Si from the zeolite framework. Investigation of the influence of temperature and time...
