Abstract

Abstract

TiO₂ nanomaterial was prepared by sol-gel method using nitric acid as the control agent. The obtained TiO₂ nanomaterial is anatase and has defect structure, with the particle size below 5 nm. During the preparation of the material, the crystal growth complies the oriented attachment (OA) mechanism. The anatase TiO₂ material was applied to the photocatalytic degradation of methylene blue, and 95% of the catalytic degradation efficiency can be achieved, showing good photocatalytic performance. It provides a simple technical path for preparation of TiO₂ nano photocatalytic materials.
