摘要
Zinc-incorporated aluminophosphate molecular sieve (ZnAPO-34) has been successfully synthesized from Zn-contained phosphatizing wastewater. More than 90% of Zn and P were removed from wastewater after synthesis. The synthesized materials were characterized by X-ray diffraction, small angle X-ray diffraction and ammonia temperature programmed desorption. As a result, these samples were proven to be typical ZnAPO-34, which possessed mesoporous structure together with a great number of Brønsted and Lewis acid sites. Furthermore, the synthesized ZnAPO-34 showed 80% catalytic activity and 80% selectivity in cyclohexane oxidation to cyclohexanol. The higher activity and selectivity could be ascribed to the incorporation of Zn in the aluminophosphate molecular sieve.
