光催化材料相关的专利分类号情况综述

摘要

通过对世界范围内的TiO2光催化材料进行检索，并对检索获得的相关专利的分类号进行统计分析，进而分析国内外相关领域的TiO2光催化材料的制备以及应用的不同。经过对光催化剂相关专利的检索分析，中国纳米TiO2光催化材料专利主要按照组成进行分类，而国外的相关专利主要按形态进行分类，此外，国外的相关专利还出现了中国专利中鲜见的超微结构的制造或处理、以及电磁辐射方面的应用。%The International Patent Classification ( IPC ) of the patents about TiO2 photocatalytic materials around the world was summaried, and the different application field and preparation methods about relevant materials in the field were analyzed. Results showed that China’s Nano-TiO2 photocatalytic materials patents mainly classified according to composition, while foreign patents mainly classified according to shape. In addition, foreign patent about relevant materials had particularly use in manufacturing or processing of ultrastructure materials, and electromagnetic radiation.
