Abstract: 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.
