以氯化铜、三氯化铁、乙二醇为主要原料，采用一步水热法制备凹凸棒石/铁酸铜（ATP/CuFe₂O₄）纳米复合材料。通过TEM、EDS、XRD、FT-IR和BET等对ATP/CuFe₂O₄复合材料进行分析；将ATP/CuFe₂O₄纳米复合材料应用于硼氢化钠催化还原对硝基苯酚生成对氨基苯酚的反应，考察了不同催化剂、CuFe₂O₄包覆量、催化剂用量等因素对硼氢化钠还原对硝基苯酚的影响。结果表明，50% CuFe₂O₄包覆量的ATP/CuFe₂O₄材料具有较高的催化活性，当ATP/CuFe₂O₄质量为5 mg时，还原可在7 min内完成。通过对ATP/CuFe₂O₄纳米复合材料的重复使用和磁分离回收，表明ATP/CuFe₂O₄具有良好的磁分离性和循环稳定性。

Attapulgite/copper ferrite (ATP/CuFe₂O₄) magnetic nanocomposites are prepared through one-pot hydrothermal method using copper chloride, ferric trichloride and ethylene glycol as raw materials.The structure and surface characteristics of the prepared materials are investigated by TEM, EDS, FTIR, XRD and BET.ATP/CuFe₂O₄ magnetic nanocomposites are used as catalyst for the reduction of 4-nitrophenol to 4-aminophenol in the presence of sodium borohydride at room temperature.Influences of various catalysts, CuFe₂O₄ coating amount and catalyst dosage on the reduction of 4-NP by NaBH₄ are studied.The experiment results show that ATP/CuFe₂O₄ material with a 50% of CuFe₂O₄ coating amount exhibits a higher catalytic activity and can make the reaction complete within 7 minutes when its dosage is 5 mg.The repeating and recovering experiments show that this catalyst has good magnetic separation and recycle stability.
