• Research Experience and Expertise
Eight years of research experience under the supervision of Dr. Birinchi K Das, Professor, Department of Chemistry, Gauhati University in the field of Catalytic Chemistry.
• Research experience as a guest worker in the National Chemical Laboratory (NCL), Pune under the guidance of Dr. A. P. Singh, Scientist F, Catalysis Division which involves the synthesis of chiral complexes and their immobilization over solid supports.
The catalytic activity of a heterogeneous oxidation catalyst, named as Co-CMS1 based on a cubane-like Co(III) oxo cluster which is immobilised on a porous organomodified silica, will be described. The heterogeneous Co(III) supported chemically modified silica (CMS) system (Co-CMS1) has been well characterized by powder XRD, SEM, TEM, BET analysis, IR, solid UV-Vis-NIR and XPS techniques. The catalyst has been found to promote the efficient and selective oxidation of benzylic alcohols and cyclohexanols with TBHP as the oxidant which can be reused without any significant loss of activity. The Co-CMS1 catalyst has also been found to catalyse efficiently the oxidation of both styrene and diphenylmethane using aqueous TBHP as the oxidant.
Audience Take away:
• I think the audience will surely get benefited by the work presented herein as the methodology developed is quite simple, advantageous and easy to handle.
• The presenter has reported an excellent heterogeneous catalytic system which definitely will be able to draw attention of the audience and also it may help in exploring its further utility and possibly might be able to extend its applicability to some other reaction system.
• Hopefully, share and exchange of ideas between the audience and the presenter will lead to a fruitful influence in the future course of research which may help in designing much more advanced as well as improved catalytic system.
