F-掺杂ZrO2粉体的水热合成及光催化性研究
Photocatalytic performance of fluorine foped ZrO2 powders via hydrothermal method
摘要
Abstract
Novel photocatalytic performance fluorine doped ZrO2 nano-powders are prepared by hydrothermal synthesis method with different concentration of HF mineralizer,and the phase composition,morphology,chemical component and photo-catalytic performance are systematically studied.The results show that the introducing of F-has great effect on the phase composition of ZrO2.With increasing the doping content of F-,the tetragonal phase of ZrO2 gradually transforms into monoclinic phase,the grain size of the ZrO2 powders increases,and the particle morphology changes from spherical particle to spindle particle.F-adsorption on the crystal face of ZrO2 ﹛001﹜ crystsl plane results in the rod-like ZrO2 crystalline grain tend to grow along[001]direction,and also make the rod-like grain oriented attached on the ﹛001﹜ crystal plane The degrading efficiency of methyl orange for all the F-doped ZrO2 powders can be higher than 80%when illuminate in 60 minutes.0.04 F/ZrO2 catalyst has the highest photocatalytic property,and the degradation rate of methyl orange can reach 91.7%in 60 minutes.关键词
