In this paper, porous CoP nanoflakes were successfully synthesized through a two-step route. Porous Co 3 O 4 nanoflakes were firstly prepared by pyrolyzing flake-like precursors. Then, porous CoP nanoflakes were produced through the low temperature phosphidation of porous Co 3 O 4 nanoflakes. The phase and morphology of the as-prepared products were characterized using powder X-ray diffraction (XRD), scanning electron microscopy (SEM), transmission electron microscopy (TEM), and energy dispersive spectrometry (EDS). Experiments showed that the as-prepared porous CoP nanoflakes presented outstanding catalytic activity in the reduction of some aromatic nitro compounds such as 4-nitrophenol (4-NP), 2-nitrophenol (2-NP) and 4-nitroaniline (4-NA), and organic dyes including Rhodamine B, pyronine B, methylene blue and safranine T, in excess NaBH 4 solution, which provided a new catalyst option for the reduction of aromatic nitro compounds and the decoloration of organic dyes at room temperature. Interestingly, the preparation approach of the precursor could affect the morphology and the catalytic performance of the final CoP nanostructures. CrystEngCommThis journal is

“…Much attention is currently focused on studying the possibility of using nickel phosphides in the field of heterogeneous catalysis in biomass hydrotreating reactions. Namely, nickel phosphides Ni 3 P, Ni 12 P 5 , Ni 2 P and Ni 5 P 4 are promising catalysts for hydrodeoxygenation [8][9][10], hydrodesulfurization [11][12][13][14][15][16] and other hydrogenation processes [17][18][19][20], due to their higher activity and stability compared to catalysts based on purely metallic Ni.…”

Nickel phosphides NixPy are a promising family of binary compounds that have shown much promise in various fields of technology, including energy storage, light absorption and heterogeneous catalysis in the reactions of biomass hydrogenation. The performance of NixPy-containing materials depends greatly on their morphology and phase composition and, in turn, on the synthesis technique. In this work, we have employed the electroplating approach to synthesize a Ni-P coating, which was treated with nitric acid in order to develop its surface area and enrich it with phosphorus. We have employed scanning electron microscopy, X-ray diffraction and 31P nuclear magnetic resonance techniques to characterize the particles separated from the coating with ultrasound for the convenience of the study. According to experimental data, the obtained powder contained a mixture of Ni3P and phosphorus oxides, which transformed into nickel phosphide phases richer with phosphorus, such as Ni5P2 and Ni12P5, after treatment at elevated temperatures. Thus, we have demonstrated that electroplating followed by acid treatment is a feasible approach for the synthesis of Ni-P coatings with increased surface area and variable phase composition.

Highly ordered mesoporous molecular sieves AlMCM‐41 and a new NiO/AlMCM‐41 nanocomposite were synthesized using a sol–gel method. Fourier transform infrared (FT‐IR) spectroscopy, X‐ray diffraction (XRD), transmission electron microscopy (TEM), scanning electron microscopy (SEM), energy dispersive X‐ray spectroscopy (EDX), and N2 adsorption desorption analyses were used to examine the structure, morphology, size and phase composition of the synthesized NiO/AlMCM‐41 nanocomposites. AlMCM‐41 embedded with NiO nanoparticles was subsequently prepared using different nickel loadings in a direct synthetic route. The results show the successful deposition of NiO nanoparticles onto the framework of AlMCM‐41. AlMCM‐41 provides enormous benefits such as environmentally safe, economic viability and porosity when used as support for NiO nanoparticles. The excellent catalytic activities of AlMCM‐41 and NiO/AlMCM‐41 were investigated for the reduction of nitrophenols (4‐NP, 2‐NP) to aminophenols (4‐AP, 2‐AP) in water at ambient temperature. The best observed performance of reduction of NP with 100% conversion into analogous amino derivatives occurred within 6 min with an estimated rate constant of 0.46 min−1. The efficiency of reduction was observed to increase as a function of NiO enrichment. The NiO/AlMCM‐41 nanocomposite could be recycled and reused up to five times without noticeable change in its structure and activity. These properties make NiO/AlMCM‐41 nanocomposite an ideal platform to study various heterogeneous catalytic processes which can have application in purification, catalysis, sensing devices, and green chemistry.
