The great demand for versatile and smart systems that operates in water makes hydrogels as a frontrunner. As the inherent green nature of many industrial and biologic reactions taking place in water, systems that function better in aquatic environment with good mechanical stability, flexibility, tunable porosity, and sensitivity to the environmental factors are well-suited for diverse applications i.e., in situ metal nanoparticle preparation and catalysis. Therefore, different functional groups such as �SO3H, -COOH, -PO3H2, N<, NH2 and OH containing hydrogels were prepared at different dimensions and used as support for metal nanoparticle preparation and as soft reactor. The chemically modified hydrogels were also employed for Co, Ni and Ru metal nanoparticle preparation and used in the hydrolysis of NaBH4. It was found that the hydrogen generation rate is strongly depended on the size, nature and porosity of the support material as well the temperature and the amount of the catalyst.
