Ni–La–B amorphous alloys supported on SiO2 and γ-Al2O3 for selective hydrogenation of benzophenone

Effects of Ultrasound and Microwaves on Selective Reduction: Catalyst Preparation and Reactions

“…Therefore, SiO2 with its planar structure and -Al2O3 with its porous structure were used as supports to improve the conversion of benzophenone and catalyst stability. [71] Benzophenone conversion increased by about 15% when using the US prepared catalyst. The sonication made the particle size smaller and enhanced the dispersion of active particles over the carriers, preserving the amorphous structure of Ni-La-B catalysts.…”

Selective hydrodeoxygenation of p-cresol as a model for coal tar distillate on Ni–M/SiO2 (M = Ce, Co, Sn, Fe) bimetallic catalysts

“…Metal-reduced catalysts are widely used in HDO processes, especially those loaded with nickel. 28,29 In general, a small amount of a binary metal, such as La, 30 Mo, 31 Cu, 32,33 or Fe, 33 is considered to improve stability and reactivity.…”

Continuous Hydrogenation of Toluene over Sr‐ and PEG800‐Modified Ni/γ‐Al2O3 Catalysts

“…However, the pure nickel catalysts are not active enough and might lead to environmental pollution during their preparation and application. Therefore, addition of metals 18, 19 and polymers 20, 21, as well as the application of supports 22, 23, have been employed to solve these problems. For example, we have prepared a series of alkaline earth metals (Mg, Ca, Sr)‐modified nickel‐based catalysts and found that a Sr‐modified Ni/ γ ‐Al 2 O 3 catalyst provided the best catalytic performance in continuous hydrogenation of hydroquinone 18.…”
