Professor Chirag B. Godiya's research lab specializes in the development of sustainable, bio-based materials for environmental remediation, with a focus on advanced adsorbents and nanocatalysts for water purification. The lab pioneers functionalized hydrogels, chitosan and wood-derived composites, and graphene-based macrostructures to remove heavy metals, pharmaceuticals, dyes, and persistent pollutants like PFAS from industrial and municipal wastewater. A key research direction involves cascaded treatment strategies—combining adsorption with in-situ catalytic conversion or regeneration—enabling resource recovery and reduced secondary waste. The lab emphasizes green synthesis, recyclability, and real-world applicability of materials derived from natural polymers and biomass.

Functionally modified natural materials based hydrogels were intensively reviewed for the adsorption of heavy metal ions, dyes, pharmaceuticals and hazardous organic micropollutants in industrial effluents.
Heavy metal ion pollution leads to severe health risk to human beings. Herein, a natural and highly efficient sodium alginate (ALG)/polyethyleneimine (PEI) composite hydrogel was designed and fabricated for the removal of heavy metal ions from wastewater. The adsorption of heavy metal ions on the ALG based, 3D composite hydrogel were thoroughly investigated in this study. Furthermore, the in situ reduced metal nanoparticle-loaded ALG/PEI composite hydrogel provided us a sustainable utilization r
We represent a copper nanoparticle (CuNPs)-templated chitosan (CS) nanocomposite as an effective catalyst for the catalytic reduction of aqueous hazardous organic micropollutants, which was synthesized via a facile in-situ reduction step of pre-chelated Cu2+ ions on CS hydrogel. The as-developed CuNPs-templated CS nanocatalyst was thoroughly characterized using several spectroscopic methods. The CuNPs-templated CS nanocatalyst demonstrated excellent catalytic efficiency in the rapid reduction of
