Electrochemical Process Engineering Overview

The research focuses mainly on the electro synthesis of inorganic chemicals like chlorate and perchlorates of alkali and alkaline earth metals and ammonium perchlorate. Also focuses on development of electrode materials for electrosynthesis of inorganic chemicals.


Major research highlights:
