Special Issue Information
Dear Colleagues,
Murray Raney used Nickel for the first time as a hydrogentation catalyst over one century ago. Since then, the field of Nickel catalysis has seen tremendous advances. During the 1970s, Nickel found extensive use as a catalyst not only for cross-coupling reactions of alkenes/alkynes, such as nucleophilic allylation, oligomerization, and cycloisomerization, etc., but also for C/H activation, oxidative cyclidation, and reduction reactions. More recently, it has been used in the formulation of catalysts assessing important environmental issues, such as CO2 chemical utilization, or as dopant of molybdenum, sulfide-containing catalysts for desulfuration processes.
Several key properties of nickel such as its thermal stability and redox behavior mean Nickel-containing catalysts are still challenging for a very large range of innovative reaction developments and industrialization.
The purpose of this Special Issue is to update the most recent advances concerning Nickel catalysts, supported or not, for innovative reaction development.

Abstract: We will review the current development of nickel-containing electrocatalysts in energy conversion applications including oxygen evolution reaction, hydrogen evolution reaction, oxygen reduction reaction, and carbon dioxide reduction reaction. The review will start with introducing synthesis strategies of nickel-containing catalysts. And then particular emphasis will be placed on the roles of the surface property and microstructure of the catalysts, as well as the synergistic effects between nickel ions and other transition metal ions on the catalytic performance. Finally, challenges and a forward-looking outlook assessing unexplored research areas and future directions is suggested. The insight of this review will spur more interest in designing the nickel-containing catalyst for energy conversion applications and propel the development of this important area.

Abstract: Green and renewable hydrocarbons prepared from catalytic hydrodeoxygenation will have a great impact on efficient ways to alleviate the global warming and drive chemical and energy companies towards a more sustainable use of resources industrial application. Biomass-derived platform molecules such as lignin and bio-oil, vegetable oils, and furfurals are of immense importance because these can be upgraded into other useful chemicals and fuels by hydrodeoxygenation. Nickel is one of the most widely used elements in metal based catalysts and its well know since the day of Ranay as hydrogen activator. But in order to provide a superior HDO performances, catalyst should have not only good hydrogen bonds dissociation ability, but also carbonyl and carboxyl groups both adsorption and activation abilities, suitable acid strength, and low carbon deposition performances. Thus despite the huge success and wide applications of the Ni catalysts in industry, usually monometallic Ni catalysts are not able to meet the activity, selectivity, and stability requirements in considered reactions. Analysis of a large number of works showed that the introduction of the second metal into the monometallic catalyst results in formation of a nano-sized alloy particles that have electronic and chemical properties that are distinct from those of their parent metals, and significantly enhanced catalytic performance. The present review highlights a detailed overview of the development of nickel-based mano- and bimetallic catalysts supported on different materials. In addition this review article provides ample information on efforts made by various researchers concerning production of green hydrocarbons by HDO of bio-derived substrates.

Abstract: Ni-Mo Hydrodesulphurization (HDS) catalyst usually contains Mo and Ni compounds supported on g-Al2O3 and V that comes from crude oil. Therefore Ni-Mo HDS catalyst is one of the most important secondary resource for recovery of Mo, Ni and V. Mechanochemical leaching method was chosen due to having combined intensive effect of grinding and leaching which in turn enhances extraction rate of valuable metals. Prior to the mechanochemical leaching experiments, spent Ni-Mo HDS catalyst was roasted at 500 oC for the elimination of residual oil and volatile compounds that bearing S and C. It is determined that roasted catalyst contains 56.95 % of Al2O3, 28.08 % of MoO3, 4.05 % of NiO, 1.15 % of V2O5, 3.33 % of SiO2 and % of 4.84 P2O5. Mechanochemical leaching of roasted Ni-Mo HDS catalyst was carried out using 100 g of zirconia grinding balls, ball/dust ratio of 10, 20 and 30, 250 mL H2SO4 solution with 0.5, 1.0, 1.5, 2 and 4 M, for 15, 30, 60, 120, 180 and 240 minutes in a planetary mill with 300, 400 and 500 rpm mill speeds for the investigation of leaching behavior of elements in roasted Ni-Mo HDS catalyst. Extraction rates of 68 %, 98 %, 76 %, 22 %, 8% and 95 % were obtained from the experiment carried out using ball/dust ratio of 20, 500 rpm mill speed, 2 M H2SO4 solution for 120 minutes reaction time for Mo, Ni, V, Al, Si and P, respectively.
