“…Thus, the catalysts are the predominant factor for the hydrogenation of 4-NP. Up to now, lots of catalysts have been tested for 4-NP reduction, including noble metals Ag [3][4][5][6][7][8], Au [26], Pt [32], AuPt [33][34], Pd [35] and non-noble metals Co [27], Cu [28][29], Fe-Ni [36], Ni [37], CuNi [39], among which most of the catalysts with high performance is still remained a considerable challenge. Therefore, development of highly effective and stable catalyst for the reduction of 4-NP in aqueous solutions under mild condition is highly desirable.…”

“…High resolution transmission electron micrographs (HRTEM) of CoCu NPs are presented in Figure . The well‐dispersed distribution of spherical morphologies of the particles with an average diameter within 5–10 nm throughout the specimen is quite clear . It is also observed that the bimetallic NPs are porous in nature.…”

Bimetallic nanoparticles (NPs) play a pivotal role in promoting high activity and selectivity towards various industrially important reactions in comparison to single metal NPs due to their modulated electronic and surface properties. Herein, we report the synthesis of non‐precious CoCu NPs, which serve as an excellent catalyst for the selective oxidation of a wide range of electronically diverse benzyl alcohols to benzaldehydes, in the presence of tert‐butyl hydroperoxide (TBHP) as an oxidant at room temperature. The excellent catalytic activity of CoCu NPs is ascribed to a two‐fold synergistic effect arising from the combination of enhanced peroxide decomposition, active Co2+ catalyst regeneration driven by the faster redox processes (between Co3+ and Cu+), and a feasible cobalt dimerisation‐regeneration process. The recoverability and reusability of CoCu NPs are also demonstrated. With the merits of low‐cost and recyclable catalysis under mild conditions, the present catalyst represents an efficient and potential alternative to precious metal catalysts.

“…Finally, the obtained results in the reduction of 4‐NP with NaBH 4 catalyzed by BOC/ZFO30% were compared with some reported catalysts in the literature . From Table , it is clear that with respect to the reaction conditions and/or reaction times, the present method is more suitable and/or superior.…”

Sheet-like Bi 2 O 2 CO 3 /ZnFe 2 O 4 magnetic nanocomposites (denoted as BOC-ZFO) with different amounts of magnetic ZnFe 2 O 4 (ZFO) nanoparticles were successfully produced by a simple hydrothermal route. X-ray diffraction (XRD), Fourier transform infrared (FT-IR) spectroscopy, scanning electron microscopy (SEM), transmission electron microscopy (TEM), atomic force microscopy (AFM), energy dispersive X-ray spectroscopy (EDX), UV-vis diffuse reflectance spectroscopy (UV-vis DRS), vibrating sample magnetometer (VSM), and N 2 adsorption-desorption examination were utilized to analyze the structure, morphology, size, phase composition, optical and magnetic properties of the synthesized nanocomposites. The results demonstrated the successful deposition of uniform ZFO nanoparticles onto the surface of sheetlike BOC nanostructures. Then, the catalytic activity of magnetic BOC/ZFO nanocamposites was investigated for the reduction of 4-nitrophenol (4-NP) to 4-aminophenol (4-AP) by using sodium borohydride (NaBH 4 ) in hydrous solution and at room temperature. The results showed that BOC/ZFO nanocamposite with 30%wt of ZFO showed the best performance in the reduction of 4-NP with 100% conversion into the amino derivative during 30 min. The effect of catalyst dosage was also investigated on the efficiency of reduction process. Under similar conditions, 2-nitrophenol (2-NP), 4-nitroaniline (4-NA) and 2-nitroaniline (2-NA) were also reduced to the amino derivatives within 16-29 min. The magnetic BOC/ZFO catalyst could be easily separated from the reaction system by an external magnet.
