Direct demonstration of enhanced diffusion in mesoporous ZSM-5 zeolite obtained via controlled desilication.
A 2 orders of magnitude gas transport improvement in a medium pore ZSM-5 zeolite has been achieved upon introduction of intracrystalline mesoporosity in gradient-free crystals by desilication post-treatment in alkaline medium.
