Metallogels & Inorganic Materials Group

Welcome to Dr. Joyee Mitra's Research Group at CSIR-Central Salt & Marine Chemicals Research Institute Bhavnagar!

We are a team of passionate chemists engaged in developing inorganic materials (especially metallogels of low molecular weight gelators), and metal-free systems with the aim to explore their applications in catalysis and in biomass conversion. Our research interests also include pollutant sequestration, healthcare and energy conversion/ storage related applications of our materials. Our group constitutes of problem-solvers who bring different ideas and perspectives in our work.

Research areas

We strive to design metal-free organic systems, both ionic and covalent, that would be effective in catalyzing important organic transformations, and in photo/electrocatalytic water splitting reactions. Their intriguing properties and morphological aspects, are of interest to us as well.
Metallogels are intriguing smart materials with potential applications encompassing diverse fields. Our goal is to design purpose-built metallogels with emphasis to self-healable metallogels, for applications in healthcare, catalytic applications, energy conversion & storage systems.
In a trash-to-treasure concept, we recover valuable metals from electronic waste, spent catalyst etc, and use them to design catalysts and other functional materials.
We are engaged in designing materials to transform plant biomass into valuable chemicals and fuel additives. We aim to harness the naturally available renewable carbon resource, with the aim to value-add waste plant biomass.
