Abstract:
1. A method for regulating a distribution of metallic compound nanoparticles within a resin support, consisting of the following steps: using a styrenic or acrylic ion exchange resin bearing basic functional groups as the resin support; introducing an anionic complex in a water solution onto the resin support through an ion exchange process, wherein the anionic complex is selected from the group consisting of FeCl providing a reductive or deposition agent, wherein the reductive or deposition agent is fixating the metallic compound nanoparticles within the resin support through a reduction or deposition process; forming a distribution ring within the resin support consisting of the metallic compound nanoparticles; and increasing a concentration of the reductive or deposition agent over the reaction time to inwardly increase a depth and a density of the distribution ring.
