Hydrogels based on various functional groups containing monomers were used as templates for different metal nanoparticle preparation. The in situ metal nanoparticles were prepared by placing the hydrogel matrices inside different metal ion solutions such as Fe, Ni, Co, Cu and Ru (prepared from their water soluble salts) and reduced to corresponding metal nanoparticles with suitable reducing agents such as NaBH4, and NH4OH within hydrogel matrices. Magnetic ferrite embedded hydrogel composites containing different metal nano catalysts were also prepared to control the hydrogen production with an externally applied magnetic field. Various parameters effecting hydrogen production rate were investigated for hydrolysis reaction of hydrogen storage materials. The macro and micro size hydrogel soft reactors as well as their silica containing composite were also probed to determine the effect of size and porosity of the soft reactors.
