Abstract

Nano-hydroxyapatite samples with different morphologies were successfully prepared by chemical precipitation method using polyethylene glycol (PEG) as a template. The phase composition, micro-morphology and surface functional groups of the nano-hydroxyapatite samples were analyzed by X-ray diffraction (XRD), scanning electron microscopy (SEM), Fourier transform infrared spectroscopy (FTIR) and transmission electron microscopy (TEM), respectively. The results reveal that the mirco-morphology of hydroxyapatite can be effectively controlled by adjusting pH values in the preparation. Moreover, the growth mechanism of HAp with different morphologies was also discussed.

Abstract

Energy-storage self-catalysis material that BiVO 4 assembled into porous Sr 2 MgSi 2 O 7 :Eu 2+ ,Dy 3+ was successfully synthesized by the impregnation method. Crystalline phases and microstructure of the energy-storage self-catalysis material were analyzed by X-ray diffraction, scanning electron microscopy, energy dispersive spectroscopy and atomic force microscope. Results indicated that BiVO 4 was assembled into Sr 2 MgSi 2 O 7 :Eu 2+ ,Dy 3+ pores physically. The photocatalysis property of the assembled sample was characterized through degrading the 5 ppm Rhodamine B solution and kinetics property was fitted according to the Langmuir–Hinshelwood formula. Results demonstrated that the assembled compounds exhibited higher photodegradation efficiency than the pure BiVO 4 no matter under the light or dark condition.
