Our group is working on a class of advanced materials, which share the advantages of both mesostructured materials and polymers of organic frameworks. The organic framework can provide numerous opportunities to tailor the chemical properties through the incorporation of a wide variety of useful organic functional groups by grafting or co-condensation. These polymers provide us with good opportunities for designing novel and innocuous support for heterogenization of a homogeneous catalyst as well as catalysts by itself. Also we are working on Value addition of biomass platform chemicals: Conversion of biomass derived alcohols and glycerol into value added products.

 

Nanoporous Materials: Nanoporous materials have gained scientific and technological importance because of the presence of their pore structures of tunable dimensions at nanometer scales. Over the last few decades, there has been an ever increasing interest and research effort in the synthesis, characterization, functionalization of nanoporous materials. The main challenges in research include the fundamental understanding of structure-property relations and tailoring of nanostructures for specific properties and applications. The main research focus of our group is the synthesis and characterization of nanostructured catalysts for various applications. Among the priorities are the development of materials with organic framework, search for new and improvement of existing catalytic systems, and studies of intimate mechanisms of heterogeneous reactions and reactant-to-surface reactions, identification of active sites.

 

 

Heterogenization of homogeneous catalysis & its application on various chemical processes: Development of new, highly efficient heterogenized catalysts is an active and important area in fine chemical synthesis. Homogeneous catalysis though has witnessed significant growth in the last few decades in terms of high selectivity, TON and TOF’s, however the success in catalyst and process development has not been in parallel by similar growth on industrial scale. Supports play a significant role in such systems. The micro environment around the catalyst active site will be the deciding factors in achieving high conversions with high selectivity. Heterogenization of homogeneous catalysts onto supports such as zeolites, nanoporoous materials like silica and polymers would be of much interest in design and development of processes for fine chemical production.
