摘要：

本文采用静态水热合成法合成了一种非水溶性固体铜铝磷酸盐(CuAlPO).研究结果发现，CuAlPO是一种与六方二氧化硅(SiO2)晶体结构相同的新型铜铝磷盐，在温和反应条件下(30℃),CuAlPO具有较高的苯酚催化羟化反应活性.

Abstract:

A new type of non-soluble copper aluminophosphate(denoted as CuAlPO) was synthesized by static hydrothermal crystallization and characterized by using several physicochemical techniques.XRD analysis reveals that CuAlPO can be obtained from a reactive gel of molar composition: iso-Pr2NH∶0.3CuO∶0.7Al2O3∶P2O5∶80H2O in a Teflon-lined stainless steel autoclave at 180℃ for 72 h and has the same crystal structure as that of hexagonal SiO2(JCPDS No.83-2299).The sources of CuO,Al2O3 and P2O5 were copper sulfate pentahydrate,aluminum isopropoxide and o-phosphoric acid(mass fraction:85%),respectively.SEM shows a characteristic hexagonal morphology and a crystallite size of about 2μm for both the as-synthesized CuAlPO and the calcined CuAlPO(550℃,6h).Low specific surace area(2.0 m2/g) and pore volume(0.004 mL/g) of CuAlPO were observed by N2-adsorption measurement.Catalytic evaluation tests demonstrate that an excellent transformation of phenol into catechol and hydroquinone over the material was achieved in water under the benign reaction conditions with a phenol conversion of 295% being observed at room temperature(30℃).
