This book chapter contains synthesis and application of zeolite, which has huge production aspect with their respective use in environmental science as catalysis. Ultrasonic method is new green synthetic tools for zeolite. The current study is focused on sustainable development of green method for the synthesis of zeolite in greener technology i.e. sonication. Coal fly ash was used to synthesis by alkali fusion and followed by sonication, in curing step is replaced by sonication method.
