Zeolite is a kind of aluminosilicate crystal with a regular pore structure, which is widely used in gas adsorption separation, industrial catalysis, and heavy metal ion pollution treatment. The hydrothermal synthesis of zeolite often uses silicon and aluminum-containing chemical products and organic template as raw materials, which is expensive and pollutes the environment. It is thus important to develop green synthetic zeolite using natural clay minerals as a raw material. This review represented recent studies on clay-based zeolite from the aspects of the activation and depolymerization process natural clay, clay-based zeolite of green synthesis process and mechanisms and some application on clay-based zeolite as solid acid catalyst, gas adsorption separation and heavy metal adsorption. In addition, the future work on clay-based zeolite was also given.
