Abstract
A method for regulating the distribution of metallic nanoparticles within the resin support is provided. This method uses the ion exchange or absorption resin bearing basic functional groups as the support; firstly introducing the metal in the form of anionic complexes onto the resin support through the ion exchange process, then realizing the purpose of regulating the distribution of the metal and its compound within the resin support by means of changing the concentration of the reductive or deposition agent in water solution and the reaction time. The regulated distribution of metallic nanoparticles within the resin support is in the form of rings with different depths and densities. The different distribution patterns result in improvements upon properties of the inorganic-organic composite material, such as reaction activity, reaction selectivity and metallic stability, and has significant referential value for preparation and structural regulation of other inorganic-organic composite materials of the same kind.
