Metallic CoNi nanoparticles anchored on heteroatom-doped carbon/MnO nanowires for improved catalytic performance

Abstract: Anchoring bimetallic alloys in one-dimensional(1D) heteroatoms-doped carbon matrix with excellent electro-conductibility is a powerful strategy for the reduction of 4-nitrophenol(4-NP). Herein, we report the design and fabrication of CoNi bimetallic nanoparticles(NPs) decorated...

“…As seen in Figure F, the k value of Ag 2 S/MoS 2 @PPy (a) nanotubes is much larger than that of Ag 2 S/MoS 2 @PPy-80 (b) and Ag 2 S/MoS 2 @PPy-20 (c), revealing the excellent intrinsic activity of Ag 2 S/MoS 2 @PPy. The tubular structure and Ag 2 S/MoS 2 NSs lead to the improved catalytic activity toward reducing 4-NP, so the excellent catalytic efficiency of Ag 2 S/MoS 2 @PPy was validated. Ag 2 S/MoS 2 NSs are covered on the PPy nanotubes to expose rich catalytic sites. Furthermore, PPy nanotubes hold a 1D tubular structure and accessible mesopores for enhancing molecular diffusion and mass transportations.…”

“…S4, † the peaks at 2θ = 44.4°, 51.7°and 76.1°can be attributed to CoNi(111), CoNi(200) and CoNi(220) planes of the face-centered cubic phase of the CoNi alloy. [36][37][38] The remaining peaks could be ascribed to the formation of MoO 2 (JCPDs no. 32-0671).…”

“…When 4-nitrophenol was mixed with NaBH 4 in an aqueous solution, the color of the solution turned from light yellow to yellow-green due to the formation of 4-nirtophenolate, resulting in the shift of the absorption peak from 317 nm to 400 nm. 46–52 Without a catalyst, no significant color change was observed within the reaction time, and only a slight decrease in the intensity of the absorption peak at 400 nm was observed (Fig. 4D(d)).…”
