Preparation of Mesoporous Bi4（GeO4）3 Microspheres from Na4Ge9020 Template Microspheres for Photodegradation of Reactive Brilliant Red X-3B

Mesoporous materials have attracted increasing attention due to their wide application. In this paper, the Na4Ge9020 microspheres were firstly prepared by solvothermal method. Then, the as-prepared Na4Ge9020 microspheres were dispersed into Bi（NO3）3 solution, and the Bi4（GeO4）3 microspheres with mes...

Description
Summary:Mesoporous materials have attracted increasing attention due to their wide application. In this paper, the Na4Ge9020 microspheres were firstly prepared by solvothermal method. Then, the as-prepared Na4Ge9020 microspheres were dispersed into Bi（NO3）3 solution, and the Bi4（GeO4）3 microspheres with mesoporous structure were formed due to the solid-state reaction between bismuth nitrate and Na4Ge9020. The morphology, structure and optical properties were characterized by SEM, EDS, XRD, FITR, BET and UV-Vis diffuse reflectance analysis. The as-prepared products exhibited excellent photocatalytic performance for degradation of reactive brilliant red X-3B under the UV light irradi- ation. A possible photocatalytic mechanism was discussed as well.
