Abstract:

Raney Ni, also known as spongy Ni, is a porous material characterized by its high surface area. Typically, Raney Ni is prepared by selectively dissolving aluminum (Al) from a Ni-Al alloy in an alkaline environment, leaving pores where Al was removed. This unique structure not only provides a high surface area but also facilitates ease of fabrication and high catalytic activity, making Raney Ni widely applicable in various chemical catalysis fields as well as in electrochemical catalysts and electrodes. To further advance the properties of Raney Ni by adding foreign elements, many strategies su

Abstract:

Selective hydrogenation of sugars (e.g. sucrose, cellobiose, glucose, fructose, xylose, arabinose) into sugar alcohols (sorbitol, mannitol, xylitol, arabitol) can be achieved by means of supported Raney Ni-based catalysts. Various supporting materials such as the layered structure of clay (e.g. bentonite, taeniolite, smectite), metal oxides (e.g. Nb2O5, ZrO2, Al2O3), and conventional supports (e.g. carbon, silica, zeolite (JRC-SZ1)) were employed to obtain high performance of supported Raney Ni-based catalysts. The conventional Raney Ni, Raney Ni/AlOH, and Ni-NP with relatively high dispersion

Abstract:

Catalysts with high selectivity play key roles in green chemistry. In this work, a granular Raney Ni catalyst using carbon as support (Raney Ni/C) was developed by mixing phenolic resin with Ni-Al alloy, conducting carbonization at high temperature, and leaching with alkaline liquor. The as-prepared Raney Ni/C catalyst is suitable for use in fix-bed reactors. Moreover, it shows high activity and selectivity for catalytic acetone hydrogenation. For instance, at the reaction temperature of 120 °C, the conversion of acetone can reach up to 99.9% and the main byproduct methyl isobutylcarbinol (MIB

Hexamethylenediamine (HMDA), a chemical for producing nylon, was produced on Raney Ni and Raney Co catalysts via the hydrogenation of adiponitrile (ADN). HMDA was hydrogenated from ADN via 6-aminohexanenitrile (AHN). For the two catalysts, the effects of five different reaction parameters (reaction temperature, H2 pressure, catalyst loading, and ADN/HMDA ratio in the reactant) on the hydrogenation of ADN were investigated. Similar general trends demonstrating the dependence of ADN hydrogenation on the reaction conditions for both catalysts were observed: higher temperature (60–80 °C) and H2 pr

Biomass gasification in supercritical water is a clean and efficient way to convert biomass to hydrogen-rich gaseous products. Appropriate catalyst can lower the reaction temperature to guarantee the technological and economic feasibility.

Abstract:

Hydrogenation of glucose into sorbitol has been a concern of researchers for a long time because it is an efficient and economical way of producing sorbitol. The researchers look for alternative metals that are higher in abundance and have good hydrogenation activity, such as nickel. In this study, porous nickel was prepared and used as a catalyst for the hydrogenation of glucose to sorbitol without adding hydrogen gas. The porous nickel needs two stages of making. First, prepare the Ni/Al metal alloys from the reduction of Ni(II) and Al(III). Second, the process of removing Al (0) metal from

Abstract:

In this work, the catalytic liquefaction of eucalyptus organosolv lignin (EOL) over hydrogen type-zeolite socony mobile-five (HZSM-5) zeolite supported transition metals in an ethanol system was studied, and a cheap transition metal NiCr/HZSM-5 catalyst was prepared. Among them, nickel and chromium proved to have a good synergistic effect, which could remarkably enhance the acidity of the catalyst surface, and the catalytic effect was better than Ru-based precious metal catalysts and commercial Raney Ni catalysts. Meanwhile, the optimal reaction process of NiCr/HZSM-5 and Raney Ni catalyst for

Abstract:

Cyclohexylamines are important and valuable key intermediates in the chemical industry, playing a crucial role in the synthesis of a variety of compounds. Developing a low-cost and efficient synthesis route for these chemicals is highly desirable but also presents significant challenges due to the complexity of the reactions involved. Herein, we designed three pathways for the production of 1,3-cyclohexanediamine (1,3-CHDA), including the one-pot reductive amination of resorcinol (RES) with ammonia and molecular hydrogen, the reductive amination of 1,3-cyclohexandione (1,3-CHD) with ammonia, a

Abstract:

Composite nanoparticles of Ni-TiC and Ni-TiN were prepared by an active plasma-metal reaction method. The structure and morphology were evaluated by X-ray diffraction and transmission electron microscopy observations. The morphology of the composite particles is dice-like or dumbbell-like, where the outer sides are metallic and the inner part of the rod (or dice)-like structure is TiC or TiN. The formation mechanism of the composite particles is considered by analogy to the VSL mechanism. The thermal stability of the nanocomposite particles is vastly superior to that of the metal particle. The

Abstract:

The effect of nickel precursors and the temperature annealing to obtain intermetallic Ni3Sn2 alloy catalysts on its activity and selectivity in the selective hydrogenation of biomass-derived furfural (FFald) were investigated. Two types of nickel precursors (c.a., i) nickel metal (Ni°) derived from Raney®nickel and ii) nickel ion (Ni2+) derived from nickel chloride) were employed as the starting materials via hydrothermal at 423 K for 24 h followed by reduction with H2 at the elevated temperature of 573-873 K for 1.5 h.
