The successful application of zeolites in diverse fields largely relies on their high stability, unique catalytic activity, and adsorptive properties. However, the property requirements for zeolites have become severe due to their diverse and demanding applications. Novel post-synthetic treatment of zeolites show that properties of zeolites can be tuned by simple liquid-mediated treatments, in which new concepts such as pore-filler stabilization and pore-opening migration have been proposed. For example, development of extremely stable zeolites that can withstand over 1000°C steaming and dealumination of small-pore zeolites, which had been believed to be impossible, were reported and further superior zeolite-based catalysts with longer catalytic life and/or improved selectivity have been realized.
