“…A higher than stoichiometric precursor ratio was initially chosen, because it is known that excess phosphorus is needed to obtain Ni 2 P [22,32]. Ni 2 P is usually the preferred nickel phosphide phase, for instance when guaiacol is being deoxygenated [33].…”

“…Moreover, the peaks at 856.1-857.2 and 134.0-134.5 eV are assigned to Ni 2+ and P 5+ [7,15], respectively. In addition, a broad shake-up peak appears at the binding energy of ~5.0 eV, which is higher than that of Ni 2+ [16,17]. These peaks can be assigned to its satellite peaks, although they are located close to those of Ni 3+ and nickel oxysulfide [18,19].…”

A series of ZnMgNiAl layered double hydroxides (LDHs) containing 20 wt.% Ni and different Zn/Mg molar ratios were prepared by a coprecipitation method, and then were introduced with H 2 PO 4 − via a microwave-hydrothermal method. With the resulting mixtures as the precursors, Zn/Mg-modified ZnMgNi-P/Al 2 O 3 catalysts were prepared. The Zn/Mg molar ratio affected the formation of Ni 2 P and Ni 12 P 5 in nickel phosphides. The ZnMgNi-P/Al 2 O 3 catalyst with a Zn/Mg molar ratio of 3:1 exhibits the best dibenzothiophene hydrodesulfurization (HDS) activity. Compared with the Ni-P/Al 2 O 3 catalyst prepared from the impregnation method, the ZnMgNi-P/Al 2 O 3 catalyst shows a higher HDS activity (81.6% vs. 54.3%) and promotes the direct desulfurization of dibenzothiophene.

“…The P/Ni molar ratio in the catalyst precursor was 2. A fraction of the phosphorous was retained by the support as surface bound phosphate-like species [6,11,16]. These PO x species can block some pores of the support and thus may significantly contribute to the loss of specific surface area (Table 1) [16].…”

Catalytic hydroconversion of propionitrile (PN) was studied over supported nickel and nickel phosphide catalysts. PN was used as model compound of aliphatic nitriles in pyrolysis oil obtained from animal by-products. Silica gel and Laponite was used as support. The structure and particle size of the supported active phase was characterized by X-ray diffractometry formation. Conversion of PN to hydrocarbon and ammonia hardly proceeded below 300 °C but became dominating reaction between 350-400 °C. Brønsted-acid sites were not required for the reactions. Supported Ni 2 P catalysts catalyzed hydrogenolysis of C-N bonds only, whereas also the C-C bonds suffered significant cleavage over supported Ni catalyst.
