摘要
采用水热法合成新型催化剂羟基磷酸铜Cu2（OH）PO4，使用XRD、TEM和IR对合成的产物进行了表征。重点研究了溶液pH值对产物的影响，发现中pH对产物生成影响最大。当pH值在7-9之间时为单羟基磷酸铜（Cu2（OH）PO4），pH大于9时得到四羟基磷酸铜（Cu5（OH）4（PO4）2）。使用获得的单羟基磷酸铜（Cu2（OH）PO4）作为催化剂催化氧化苯酚，利用气相色谱对催化剂的催化活性进行了表征。
The synthesizing of copper hydroxyphosphate Cu2 （OH）PO4 by hydrothermal reaction were reported. The products were characterized by X-ray diffraction analysis, TEM and IR. The results show that the products are pure and in orthorhombic phase. Effecting of the temperature, pH and reaction time on products were studied. While pH = 7-9, Cu2（OH）PO4 are obtaine＆ While pH 〉 9,Cu5（OH）4（PO4）2 are produced. Copper phosphate hydroxide was used in catalyzed oxidation of phenol and results were examined the catalyst efficiency by GC.
