The development of sustainable processes for chemical synthesis, energy and petrochemical technologies is one of the major challenges and noteworthy task for 21sr century. Notably, catalysis is a key technology for achieving more sustainable processes in the chemical, pharmaceutical and material industries. Currently, more than 80% of all chemical products are made via catalysis. In this regard, the development of more selective, cost-effective and durable catalysts constitutes a key factor for the production of all kinds of chemicals today and in the future. Since decades, the catalysts based on noble metals have revolutionized organic synthesis at scales ranging from the lab bench to the industrial manufacture of fine and bulk chemicals. However, the high price and limited availability of these precious metals has spurred interest in catalysis with more earth-abundant non-noble metal alternatives. Due to ease of isolation and recyclability, the development of heterogeneous catalysts for advanced organic synthesis represents an important topic. In the talk, the different approach (using homogeneous organometallic complexes) for the development of nitrogen doped graphene activated Fe- and Co-oxide based nano-structured heterogeneous catalysts, which can be useful for the advancement of cost-effective industrial processes, will be presented. The talk also includes the catalytic applications of these Fe- and Co-based materials for precious hydrogenation and green oxidation processes in the sustainable synthesis of valuable chemicals such as functionalized and structurally diverse amines, nitriles, amides, esters, epoxides etc., under industrially viable conditions. Also, the synthetic utility and practical applicability (upscaling from academic lab to industry) of these catalysts for the industry will be demonstrated. Further, the development of MOFs derived nano-structured materials for the advanced synthetic applications will be presented. Finally, specific synthetic examples in homogeneous catalytic hydrogen barrowing methodology and C-H activation will be shown.
Jagadeesh is presently a Senior Scientist and Project Leader in Leibniz Institute for Catalysis (LIKAT-Rostock) at the University of Rostock, Germany. He was born and grown up in Bangalore (silicon and software city) India. He is married and having one son. He obtained M.Sc. and Ph.D. in Chemistry from Bangalore University, India. After being worked as postdoctoral fellow at the University of Florida, USA and a year Assistant Professor at VIT University, he has joined Prof. Matthias Beller department at LIKAT-Rostock in the year 2010. His main research area belongs to catalysis and sustainable organic synthesis. He has developed number of essential catalysts and synthetic processes for fine and bulk chemicals; some of these catalysts are in the pipeline of commercialization. His important works have been published in Science with cover picture, in four Nature publishing journals, JACS, Angew Chem Int Edn and other reputed journals. Also key works have been highlighted in the Cover of Science, Nature, Science, Chemical & Engineering News (C&EN), Chemistry World and Perspective in Science.
All faculty, researchers and graduate students are invited to attend.
There will be a get-together with refreshments at 10:45-11:00 a.m.
