The hydrogen uptake values were used to determine the catalyst properties of Ni/CeO 2 like dispersion, metal area, and particle size. Among the two preparatory routes, co-precipitation method gave better catalytic performance in terms of hydrogenation activity, benzene selectivity, and coking ...
(8.1 wt%) on a graphitic carbon nitride support. For the semi-hydrogenation of acetylene in excess ethylene, the fabricated catalyst shows extraordinary catalytic performance in terms of activity, selectivity and stability—far superior to supported atomic nickel alone in the absence of a ...
“Nickel compounds,”“nickel-based catalyst,” and “nickel oxide” underline the importance of nickel in catalyst formulation. Keywords like “electrocatalysis,”“hydrogen evolution reactions,” and “water splitting” reflect the electrochemical reactions essential for efficient hydrogen production. “...

This highly reduced complex 1 is one of the most active nickel catalyst precursors for the hydrogenation of C=C double bonds. The mild conditions tolerate hydroxyl, halide, ester, and lactone functionalities. Mechanistic studies, including reaction progress analyses, poisoning experiments, and ...
The catalytic performance is highly related to the catalyst structure. Herein, a series of Ni nanoparticles supported on Y2O3 with different morphologies w
being beneficial to improve its activity.Nano nickel was 2.01 times more active in hydrogenating first-grade soybean oil than raney nickel.When the iodine value of hydrogenated oil was about 90 gI/100 g,the selectivity of nano nickel catalyst was 0.51 for linoleic acid and 0.35 for trans ...
