Abstract
Abstract A method for obtaining an interaction between reagent/s in a solid support and diffusible solute/s or components in an adjacent liquid or gas phase wherein said reagent/s are trapped in a sol-gel glass (hereinafter also referred to as doped sol gel glass) which provides the solid support to the reagents, wherin a sol-gel glass is any ceramic or organoceramic material prepared by polymerization of suitable monomers, such as metal alkoxide mixtures, wherein the polymerization is carried out through the sol gel-xerogel stages.
