Research Description

Environmental Chemistry is the study of chemical processes occurring in the environment which are impacted by human activities. These impacts may be felt on a local scale, through the presence of urban air pollutants or toxic substances arising from a chemical waste site, or on a global scale. The field of environmental chemistry is both broad and highly interdisciplinary. Within the Department of Chemistry, we are core group of the faculty, whose research interests are development of new materials and their environmental applications. We interact with numerous other researchers at the University who have related interests, and with industries & government agencies. The focus of our research activities is the development and study of new composite materials using bio-wastes with inorganic materials, synthesis of ionic liquids and their applications in the environmental remediation. These new materials have very interesting and potentially useful properties for the remediation of environmental pollutants. In addition, we are also working on the potential use of plant peroxidases & development of advanced oxidation processes like Fenton and Photo-Fenton processes for the treatment of industrial effluents. We mainly focus on the following aspects:

  • Treatment of industrial effluents containing organic and inorganic pollutants using agricultural wastes
  • Synthesis and modification of composite materials based on agricultural wastes
  • Synthesis and environmental applications of ionic liquids
  • Synthesis of inorganic nanoparticles for environmental remediation processes
  • Treatment of industrial effluents using advanced oxidation processes
  • Remediation of organic pollutants using plant peroxidases
  • Biocatalysis: kinetic and thermodynamic studies of industrially important enzymes

Research Group 2

Research Description
The research group is mainly working in two regimes, (a) Radiation chemistry (b) renewable energy (mainly solar energy). Ionizing radiations cause chemical changes in the molecules of the interacting medium. Our research group is working on application of ionizing radiation in food chemistry, wastewater treatment, textile industry and polymer synthesis. The food preservation is key parameter to meet the food security requirements. Irradiation of foodstuff with gamma radiation is being used to increase their shelf life. We are working on development and standardization of various methods, which have potential to discriminate the irradiated foods from the un-irradiated. Additionally, the reduction of aflatoxin in different types of foodstuffs by high-energy radiation is also being investigated. One of the interesting avenues is the use of high-energy radiation for the degradation of toxic formulations present in the industrial effluents and their conversion into environment friendly residues. We are working on the fabrication, characterization, and application of nano-materials (nano photocatalysts, nanocomposites, etc.), which can be used for degradation of pollutants in wastewater. The research group is also working on the effect of radiation on extraction as well as on dying of textile fabric. Synthesis of novel variety of polymer such as UV-curing of polymers and coatings, polyurethane functionalized by carbohydrate and dyed polyurethane elastomers with interesting applications in textile industry. The potential of renewable energy sources is enormous as they can very meet the world’s energy demand. Sunlight is a clean, renewable and inexhaustible energy source on the earth. The hydrogen gas (H2) can be produced directly from abundantly available and solar light through photo-electrochemical water splitting. Our goal is to create a distinctive venue focused on solar hydrogen production through fabrication of novel nano-structured photo-electerodes. In photovoltaics, our research interests include the generation of photoactive nano thin films and their application in dye-sensitized solar cells, design and synthesis of photovoltaic (PV) materials, design of photovoltaic materials with computational approach, synthesis and application of ionic liquids as solar cell electrolyte solution, etc. In energy sector, research on desulphurization of coal matrix by different physicochemical methods is also being carried out by our research group.
