“…They found that the application of microwave heating could significantly improve the efficiency. Two years later, they further investigated the effects of the operating parameters of this microwave system . Interestingly, the reaction was a nonisothermal process when it was carried out under low microwave power but was an isothermal process under high microwave power.…”

Raney Ni is a class of fine-grained heterogeneous catalysts composed mostly of nickel that is widely applied in organic synthesis and a large number of industry processes. In the past 10 years, various excellent research achievements have been obtained due to the emerging field of biomass conversion, which opened another dimension to this catalyst. This review starts with a brief introduction to the history of Raney Ni from its creation to its development. The subsequent sections provide a comprehensive discussion of the synthetic strategies and their controls from the perspective of structure and composition. We focus especially on the current applications in biomass conversion, including the catalytic upgrading of raw biomass resources and the derived platform chemicals. In this review, we try to gain a great understanding of this unique catalyst and its special role in biomass conversion in comparison with supported Ni catalysts. The outstanding catalytic performance of Raney Ni may inspire researchers to explore more elegant preparation methods and emerging applications.

The rapid depletion of fossil-derived fuels along with rising environmental pollution have motivated academics and manufacturers to pursue more environmentally friendly and sustainable energy options in today's globe. Biodiesel has developed as an ecologically favorable alternative. However, the mass manufacturing of biodiesel on an industrial scale confronts substantial cost and pricing challenges. To address this issue, highefficiency catalysts with a large number of active sites are needed, resulting in increased biodiesel output and quality. Metal−organic frameworks (MOFs) have received a lot of interest as a catalyst for converting oils/fats or fatty acids into biodiesel. MOFs are polyporous materials that can alter pore size as well as topological structure. They serve as a versatile foundation for designing active sites to satisfy the unique needs of catalytic reactions and conversion pathways. The purpose of this current work is to shed light on the underlying mechanisms and essential properties of MOF-based catalysts used in biodiesel synthesis. In addition, several methods for connecting active sites inside MOFs are scrutinized, while the properties and usability of MOF-based catalysts for the biodiesel production process are completely compared to other catalysts. More importantly, limits and future research directions about the utilization of MOFs in the biodiesel synthesis route are also critically presented. In general, this review contributes to improved awareness about the potential of MOFs in the biodiesel production sector by investigating the primary mechanism and characteristics of MOF-based catalysts.

“…Therefore, the process of CTH should be strengthened using an intensification approach to reduce the reaction time and temperature of CTH. 13 Microwave heating, as a process intensification approach, possesses some superior features such as uniform and molecular-level heating effect, short heating duration and high energy efficiency. 14 Thereby, microwave heating is a potential technique for intensifying CTH reaction due to that using microwave heating is helpful to promote the reaction rate with a reduction in energy consumption and reaction time.…”

Modified nickel-boride (Ni-B)-based amorphous alloy catalysts used for microwave-assisted catalytic transfer hydrogenation (CTH) of fatty acid methyl esters (FAMEs) had been synthesized via chemical reduction method by adding simultaneously cetyltrimethylammonium bromide (CTAB) and various transition metals. The results suggested that Cr-doped Ni-B-CTAB catalyst showed superior catalytic activity. It was found that Ni-Cr-B-CTAB catalyst remained an amorphous structure and had a smaller particle size with less agglomeration as compared with Ni-B catalyst. What's more, the specific surface area of the catalyst increased obviously with the addition of CTAB and Cr into Ni-B catalyst. Under the established optimum conditions of CTH using Ni-Cr-B-CTAB as a catalyst, the conversion ratio of methyl linoleate reached 78.05% and the properties of hydrogenated FAMEs were improved obviously. This work has provided a feasible approach to prepare a new and efficient Ni-Cr-B-CTAB amorphous alloy catalyst for the CTH of FAMEs and thus to obtained the high-quality hydrogenated FAMEs.
