The present research aims to design and produce a unique and magnetically rectifiable catalyst through immobilizing copper(II) over the Fe₃O₄@SiO₂ nanoparticles (NPs) surface. The fabricated catalysts were determined as VSM, EDS, XRD, FT-IR, TG-DTG, and FESEM procedures. The prepared catalyst demonstrated superior catalytic performance in the reduction of Cr(VI) and 4-nitrophenol (4-NP) and degradation of organic dyes like methylene blue (MB) and congo red (CR) in aqueous media. Remarkable attributes of this method are high efficiency, removal of a homogeneous catalyst, easy recovery from the reaction mixture, and uncomplicated route. The amount of activity in this catalytic system after several stages of recovery and reuse was almost constant. In general, NaBH₄ induced degradation/reduction of MB, CR, and 4-NP, and formic acidinduced reduction of chromium(VI) to chromium(III) catalyzed with prepared catalyst within a very short time. Moreover, compared to related research, this catalyst showed less reaction time.

本研究旨在通过将铜 (II) 固定在 Fe ₃ O ₄ @SiO ₂上来设计和生产一种独特的磁整流催化剂。纳米颗粒 (NPs) 表面。制备的催化剂通过 VSM、EDS、XRD、FT-IR、TG-DTG 和 FESEM 程序确定。所制备的催化剂在水性介质中还原 Cr(VI) 和 4-硝基苯酚 (4-NP) 以及降解有机染料如亚甲蓝 (MB) 和刚果红 (CR) 方面表现出优异的催化性能。这种方法的显着特点是效率高、去除均相催化剂、易于从反应混合物中回收以及路线简单。经过几个阶段的回收和再利用后，该催化系统中的活性量几乎是恒定的。一般来说，NaBH ₄诱导 MB、CR 和 4-NP 的降解/还原，以及甲酸诱导的铬 (VI) 在很短的时间内被制备的催化剂催化还原为铬 (III)。此外，与相关研究相比，该催化剂的反应时间更短。
