TiO2光催化剂在净化空气领域的中国专利技术分析

摘要

Chinese patents regarding TiO2 photocatalyst in air purification were analyzed and studied from application perspective. It was shown that study on the morphology and the structure of nano TiO2 has gained significant progress;study on new preparation method and new structure shall be the focus in future research of TiO2 nanomaterials;and domestic applicants in universities and institutes were much more than that in enterprises,so it was necessary to strengthen the cooperation between enterprises and academies.%从专利申请出发，分析和研究了二氧化钛光催化剂净化空气领域的中国专利申请情况。研究表明，在已有二氧化钛结构和形貌的研究基础上，应用领域的研究已臻成熟，继续研究新的应用会有很大难度，对已有的应用技术进行改进是可行的技术路线；同时开发新的制备方法及新型结构的二氧化钛纳米材料，成为研究的热点；国内申请人主要集中在高校和研究院所，企业申请较少，建议企业和高校及研究院所加强合作，互相取长补短。
