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. The current focus of our group is to utilize mesoporous polymers as catalyst support for heteroligation of homogeneous catalyst and utilize them for important organic transformations such as oxidations with environmentally benign oxidants for e.g. hydrogen peroxide (H2O2). 

Synthesis and Catalytic Applications Metal Organic Framework (MOFs)

The metal organic frameworks (MOF’s) are the advanced materials with exceptional textural properties. Catalysis by MOFs mainly depends on the active sites, both metal centres and organic linkers. Organic bridging linkers are used as scaffolds to which distinct catalytic complexes, biomolecules, and homogeneous catalysts can be immobilized or encapsulated.  These materials are known for their textural properties such as high surface area, intrinsic porosity, a high percent of transition metal content, and accessibility of guest molecules into the pores. The beneficial properties of the metal organic frameworks made them excellent material for catalytic applications.  In the last two decades, MOFs have presented a significantly amplified role in heterogeneous catalysis as they have been considered as eco-friendly alternatives for catalysis. The ongoing research work in our group aims at the synthesis of MOFs with good thermal stability and high surface area. In addition, MOF-derived carbon-based materials are used in the proposed organic transformations.

Miss. Bhavana. B. Kulkarni (Research scholar)I did my bachelor's degree (BSc) from Rani channamma University Belagavi and a Master's in general chemistry at SB Arts and KCP science college, Bijapur, from Rani Channamma University Belagavi, India. I joined the materials science and catalysis division at PPISR.My area of interest is Metal-organic frameworks (MOFs), which are crystalline materials constructed by the co-ordination linkage between secondary building unit (SBU)/ metal cluster and bi- or multipodal organic linkers. The interesting properties of MOFs include well defined pores, high tunable pore surfaces, flexible nature, and rational design of their structures. Lately, these materials have gained the tremendous research interest in the different sectors such as catalysis, hydrogen storage and carbon dioxide capture. This project aims at the synthesis of MOFs and MOF-derived carbons with goodthermal stability and high surface area. These materials are used in the different organic transformations.
