METHOD FOR PREPARING A HYDROXYL RADICAL GENERATING COMPOSITION AND A HYDROXYL RADICAL GENERATING COMPOSITION PREPARED BY COATING A TRANSITION METAL COMPOUND IMMOBILIZED SHELL ON THE SURFACE OF A SUPEROXIDE GENERATING COMPOUND IMMOBILIZED CORE

摘要

PURPOSE: A method for preparing a hydroxyl radical generating composition and a hydroxyl radical generating composition prepared by the same are provided to naturally generate hydroxyl radicals without the irradiation of light or plasma.;CONSTITUTION: A method for preparing a hydroxyl radical generating composition comprises: a core forming step of immobilizing superoxide generating compounds on the surface of a first silica precursor (S100); and a shell forming step of coating a shell, which is prepared by immobilizing transition metal compounds on the surface of a second silica precursor, on the external surface of the core (S200).;COPYRIGHT KIPO 2013;[Reference numerals] (S100) Core forming step; (S200) Shell forming step
