Advances in Hydroxyl Free Radical Assisted Synthesis of Zeolite

As one of the most important solid catalysts in chemical industry, zeolites are widely used in different fields.How to prepare zeolites greenly and efficiently has become a research hot issue with the increase of consumption year by year.Hydroxyl free radical is a highly active species, which can promote the depolymerization and repolymerization of aluminosilicates in the zeolite initial gel, and then accelerating the zeolite crystallization process.Besides accelerating the crystallization of zeolite, many studies have shown hydroxyl free radicals have other functions in zeolite synthesis.In this review, the role of hydroxyl free radicals in the synthesis of zeolites is systematically introduced via different generation methods.The challenges of the hydroxyl free radical assisted strategy are put forward, and its development directions are prospected.
