A feasible approach to the synthesis of nickel phosphide for hydrodesulfurization

Hydrodeoxygenation of methyl palmitate over MCM-41 supported nickel phosphide catalysts

“…In our previous studies, metal phosphide catalysts were synthesized by the direct reduction of oxide precursors [17], which uses a low H 2 flow speed and is not affected by the heating rate. The reduction temperature of the metal phosphate precursors was same as that used in the DR method.…”

“…In our previous studies, metal phosphide catalysts were synthesized by the thermal decomposition of metal hypophosphite and oxide precursors [13][14][15][16][17]. The oxide precursors were, however, obtained from the calcination of metal phosphate in air in a muffle furnace at 600 • C. This step will limit the application of some carrier, such as carbon, which will react with oxygen at high temperatures and waste energy.…”

“…The role of cations and anions in the synthesis of metal phosphides also was studied. Compared with the traditional temperature-programmed reduction method [18][19][20] and direct reduction (DR) method [17], the metal phosphate precursors could be directly reduced in a H 2 atmosphere and skip the step of calcination in a muffle furnace at 600 • C. Various Ni 2 P/MCM-41 catalysts were synthesized and tested for the HDO of methyl palmitate, which is a derivative of palm oil and widely distributed in nature. Compared with palmitic acid, methyl palmitate has a lower melting point (30 • C), and is more suitable for use in laboratory studies.…”

Ni2P clusters on zeolite nanosheet assemblies with high activity and good stability in the hydrodesulfurization of 4,6-dimethyldibenzothiophene

“…Metal phosphides (MoP, WP, and Ni 2 P) are a novel group of catalysts for deep hydrotreating [25][26][27]. In particular, Ni 2 P supported on silica (Ni 2 P/SiO 2 ) [28,29] and mesoporous siliceous materials (Ni 2 P/MCM-41) [30,31] has received much attention due to its high intrinsic hydrogenation activity. However, the industrial applications of these catalysts are still limited due to their unsatisfactory total HDS activity and instability.…”

A complexant-assisted hydrothermal route for the synthesis of nickel phosphide

“…While the combination of transition metal phosphides and different shapes may acquire more interesting properties and applications. Until now, various metal phosphides with different shapes and properties have been reported [19][20][21][22]. Li et al [23] synthesized Ni 12 P 5 hollow microspheres via a facile hydrothermal route, and showed that Ni 12 P 5 hollow microspheres had a well-photocatalytic degradation property of Safranine T (68 %).…”
