英文摘要: Microporous phosphate crystals with submicron holes, HAP-TAP, was hydrothermally prepared. HAP-TAP is composed of two different crystals, the hexagonal prism crystals and the layer crystals. Its morphology was characterized by abundant submicron holes (0.4 - 0.8 mu m) distributing on the surface of hexagonal prism crystals and the layer crystals growing in the holes. The process of crystallization was investigated by scanning electronic microscopy, powder X-ray diffraction (XRD), infrared spectroscopy, and energy dispersive X-ray (EDX) spectroscopy. The hexagonal prism single-crystal HAP was obtained by adjusting the crystallization time. The single-crystal XRD results showed that HAP is a novel microporous aluminum phosphate with a formula of Al-5(OH)(2)(PO4)(7)(C2N2H10)(3)center dot 0.5H(2)O and two-dimensional open-framework structure. EDX results showed that the layer crystals located in submicron holes were titanic aluminum phosphates.
