摘要
采用均匀实验设计研究了水热法合成羟基磷酸铜,并用粉末X射线衍射分析、扫描电子显微镜、傅里叶变换红外光谱、差热-热重分析等对合成的羟基磷酸铜进行了表征.优化的合成配比为:n(乙二胺)∶n(磷酸)∶n(乙酸铜)∶n(水)=1.0∶9.5∶7.25∶399,在此条件下可以稳定合成羟基磷酸铜纯相.超声预处理原料混合物可使合成时间缩短,产品粒径更均匀,合成的羟基磷酸铜具有很高的催化降解对硝基苯酚的活性.
The hydrothermal synthesis of copper hydroxyphosphate is studied by uniform design method.The product synthesed was characterized by XRD,SEM,FTIR and TG-DTA.The optimal synthesis ratio is ethylenediamine/phosphoric acid/copper acetate/water（molar ratio）= 1/9.5/7.25/399.Under the optimal condition,the pure phase of copper hydroxyphosphate can be synthesed reliably.The synthesis time is short and the crystal size of product is uniform in the case of ultrasonic pretretament for the mixture of raw materials.The copper hydroxyphosphate synthesed has very high activity for the catalytic degradation of p-nitrophenol.
