MESOPOROUS INORGANIC COMPOSITE POWDER CONTAINING METAL ELEMENT IN ITS STRUCTURE AND THE METHOD FOR MANUFACTURING THEREOF

摘要

Disclosed are mosoporous inorganic composite powder, which is prepared through a simple process in an economic manner by partially substituting silica in the framework structure of mesoporous silica powder with a metal element, such as titanium or zinc, and at the same time, maintains structural uniformity similar to that of a mesoporous material consisting of a pure silica framework, as well as a preparation method thereof. Also disclosed is mesoporous inorganic composite powder, which is prepared by further loading metal oxides, such as cerium and iron, into the pores of said metal -substituted mesoporous inorganic composite powder, and thus has UV (UV-A and UV-B) blocking ability in a wide wavelength range and improved touch and safety, as well as a preparation method thereof.
