Copper (II) immobilized on l-arginine-β-cyclodextrin-functionalized magnetite nanoparticles (nano-Fe₃O₄@l-arginine-CD-Cu(II)) was successfully synthesized and fully characterized using FT-IR, XRD, SEM, EDX, ICP, TGA and VSM techniques. The catalytic activity of these magnetically retrievable nanoparticles was evaluated in the direct oxidation of primary alcohols and benzyl halides to acids in neat conditions that was observed to proceed well and products were obtained in good yields. In addition to showing good catalytic activity, the magnetic catalyst is easy to synthesize and can be recycled at least five times with little loss in activity.

成功合成了固定在1-精氨酸-β-环糊精官能化的磁铁矿纳米粒子上的铜（II）（纳米-Fe ₃ O ₄ @ 1-精氨酸-CD-Cu（II）），并利用FT-IR，XRD，SEM对其进行了充分表征，EDX，ICP，TGA和VSM技术。这些磁性可回收纳米粒子的催化活性在伯醇和苄基卤化物在纯净条件下直接氧化为酸的过程中进行了评估，观察到进展良好，并以高收率获得了产品。磁性催化剂除了显示出良好的催化活性外，还易于合成，并且可以循环使用至少五次，而活性损失很小。
