Copper-Based Integral Catalytic Impeller for the Rapid Catalytic Reduction of 4-Nitrophenol

Abstract: The integral catalytic impeller can simultaneously improve reaction efficiency and avoid the problem of catalyst separation, which has great potential in applying heterogeneous catalysis. This paper introduced a strategy of combining electroless copper plating with 3D printing technology to construct a pluggable copper-based integral catalytic agitating impeller (Cu-ICAI) and applied it to the catalytic reduction of 4-nitrophenol (4-NP). The obtained Cu-ICAI exhibits very excellent catalytic activity. The 4-NP… Show more

“…The reaction is considered pseudo-first order with respect to the concentration of 4-nitrophenol. A similar trend was reported in the literature for various supported catalysts [32,34,41,[56][57][58][59]. Figure 9 shows that the SiO 2 /MoO 3 (1:3), SiO 2 /MoO 3 (2:2) and SiO 2 /MoO 3 (3:1) nanocomposites can be reused up to four times without significant loss in their catalytic efficiency.…”

“…The value is about 59 times and 4.5 times higher than those of SnO 2 NFs (7.1 × 10 -5 S -1 ) and MoS 2 NSs (9.2 × 10 -4 S -1 ), respectively [31]. Classical reduction catalysts are made from mostly toxic and expensive noble metals such as Au, Pt, Pd, and Ru [32][33][34][35]. On the other hand, MoO 3 has attracted progressive attention as an alternative to the noble metals catalysts perhaps due to its low cost, nontoxicity, and the existence of multiple oxidation states.…”

“…In the literature, a few researchers have reported the reduction of pNP over metal-free catalysts such as graphene and MOFs-based catalysts [ 12 , 16 ]. However, metal [ 17 , 18 , 19 , 20 , 21 , 22 ] and metal oxide [ 21 , 22 , 23 , 24 , 25 ] nanoparticles and nanocomposites have widely been applied, due to their excellent efficiency in lowering the reduction potential value [ 26 , 27 , 28 ]. Furthermore, their adaptable morphological, structural, chemical, physical, and optical properties have contributed to utilizing them in a wide area of research, including sensing, imaging, electronics, adsorption, and heterogeneous catalysis [ 15 ].…”

“…Furthermore, the Cu-based materials showed a high catalytic performance for the reduction of 4-NP. Some of the recent papers include Cu–COF, 24 Cu 55 , 25 CNF/PEI2-Cu, 26 Cu–Cu 2 O, 27 Cu-doped glass, 28 Cu NPs/SG, 29 Cu-ICAI, 30 Cu NPs/boron nitride, 31 PZS@Ag–Cu NP composites, 32 and Cu/ZnO. 33 However, the application of Cu/HAP as a catalytic system for the reduction of 4-NP has not yet been reported, to our knowledge.…”
