The aim of this review paper is to give an overview of the development and implications of nano particles synthesis which is an emerging field that covers a wide range of applications. It play a major role in the development of innovative methods to produce new products to suitable existing production equipment and to reformulate new material and chemicals with improved performance resulting in less consumption of energy and material and reduce harm to the environment as well as environmental remediation. Nano catalyst is an expected to be fruitful areas which are synthesized recently by different methods. Current applications and research into the use of Nano catalyst in waste water management, textile, agriculture, and medicine has also been reviewed.
