Gel-based materials have recently emerged as versatile platforms for addressing challenges in green chemical processes, clean energy, and environmental remediation. Their three-dimensional polymeric networks, high liquid-holding capacity, and tunable physicochemical properties make them adaptable to multiple sustainable applications.

In our work, we focused on the design and functionalization of gels derived from bio-based polymers and ionic liquids to create eco-friendly alternatives for chemical processing. Our experimental results demonstrated that ionogels not only improved catalyst retention but also enhanced reaction selectivity, leading to reduced solvent usage and lower waste generation. Similarly, organogel-supported catalytic systems were successfully tested in esterification reactions, achieving higher yields under mild conditions compared to conventional methods.

In the energy domain, we developed gel polymer electrolytes with optimized porosity and surface functionality. Electrochemical studies revealed improved ionic conductivity and thermal stability, which translated into better cycling performance of prototype lithium-ion cells. Notably, the gels retained flexibility and stability even after multiple charge–discharge cycles, with only a minor decrease in conductivity.

For environmental applications, we fabricated bio-inspired hydrogels functionalized with natural additives. Adsorption experiments confirmed their efficiency in removing heavy metals and organic dyes from water, with recyclability over several cycles showing only a slight decline in adsorption capacity.

This integrated investigation underscores the potential of gel-based materials as sustainable, multifunctional systems that bridge green chemistry, clean energy, and environmental solutions.
