以正十六胺（HDA）为插层材料，用二正丁胺（DBA）控制pH，合成了层状羟基磷酸铜（Cu₂（OH）PO₄）纳米片。在水热条件下将正硅酸乙酯（TEOS）与羟基磷酸铜层间的HDA进行交换，通过焙烧制得Cu₂（OH）PO₄-SiO₂复合纳米材料。用X射线衍射（XRD）、红外吸收光谱（FT-IR）、扫描电子显微镜（SEM）和紫外-可见漫反射吸收光谱（UV-Vis）等方法对样品进行表征。通过罗丹明B的可见光-芬顿催化降解反应，考察了所得样品的可见光-芬顿催化活性。结果表明，复合后的Cu₂（OH）PO₄-SiO₂材料的催化性能较复合前的Cu₂（OH）PO₄纳米片明显提高。

Stratiform copper hydroxy phosphate nanoplates are synthesized by using hexadecyl amine (HDA) as the intercalation material and dibutyl amine (DBA) as the pH adjuster. HDA between layers of copper hydroxy phosphate is replaced by tetraethoxysilane (TEOS) under hydrothermal condition, then the Cu₂(OH)PO₄-SiO₂ composite nanomaterials are prepared via calcination. The sample is characterized by XRD, FT-IR, SEM and UV-Vis. The visible-light photo-Fenton catalytic activity of the sample is evaluated through the catalytic degradation of Rhodamine B. The results show that the visible-light photo-Fenton catalytic performance of Cu₂(OH)PO₄-SiO₂ composite nanomaterial is obviously higher than that of Cu₂(OH)PO₄ nanoplate.
