Environmental Nanotechnologies

About the group

The main emphasis of the “Environmental Nanogroups” at RCPTM has been the design and development of advanced nanomaterials and technologies for the applications in environmental chemistry including sustainable applications in catalysis. Presently, our group is working on three major areas: 1) Earth-abundant materials for environmental applications, 2) benign catalytic applications and 3) photo- and electrochemical applications. The first area encompasses the development of iron-based species (namely zero-valent iron, ferrates etc.), for the environmental applications including water purification by removal of toxic materials, investigation of ecotoxicity of metal-based nanoparticles etc. The second area focusses on the catalytic applications of metal, metal-oxide, carbon-based nanomaterials for important organic transformations. In this category, our progress in the field of iron-oxide supported catalytic systems offers unique advantages of high recyclability and magnetic separations, thereby making such processes more environmentally friendly as well as economical. In addition, our recently installed state-of-the-art microwave and “Flow reactor” also contributes significantly in enhancing the productivity of the group. Finally, the recent upsurge in the field of photo- and electro-chemistry particularly for their energy-related applications including solar cells, electrocatalysis etc. have also prompted us to be a part of this endeavor and we have been engaged in developing novel materials to be applied in photo- and electrochemical applications.

As these areas are quite inter-related, given the strength of our group members with different expertise, we have also been continuing our successful collaboration not only within the groups, but also outside the group (both at academic as well as industrial levels).

Research Areas:

  • Zero-valent iron chemistry and applications
  • High-valence states of iron – ferrates (IV,V,VI)
  • Catalysis, green chemistry
  • Carbon supported catalysis
  • Core-shell nanocatalysis
  • Ecotoxicity of NPs
  • Photoelectrochemistry, solar cells, light harvesting
