Zeolites with uniform micropore have been widely applied in the industrial processes, giving great economic and social benefits. However, current synthesis of zeolites is still not sustainable, which strongly hinder their wide applications. In the past decades, great progresses have been made in sustainable synthesis of zeolites, including design of organic templates, organotemplate-free, solvent-free, fluoride-free, and the combination of organotemplate-free and solvent-free routes. The sustainable routes would significantly reduce the cost and wastes for the production of zeolites, which is potentially important for carbon neutrality in the future.
