The hydrogels from 2-acrylamido-2-methyl-1-propansulfonic acid (AMPS), 2-acrylamido glyconic acid (AAGA), N-vinyl imidazole (VI), and sulfopropylmethacrylate (SPM) that can absorb metal ions such as Co, Ni, Rh, Ru ye Pt from aqueous media were used in the preparation of homo or copolymeric hydrogels and their organic-inorganic composites with tetraethoxy silane (TEOS), tertamethoxysilane (TMOS) and vinyltriethoxysilane (VTEOS), or vinyltrimethoxyilane (VTMOS) as hydrogel-silica composites. The prepared hydrogel and their silica composites were used as template in Cu, Ag, Co, Ni, Fe etc, and magnetic ferrite particle preparation. The prepared hydrogel metal composites were used as a smart catalyst system with controllable porosity for the production of hydrogen in the hydrolysis of different hydrites such as NaBH4 is a novel concept and a smart approach.
