“…Recently, Rong and co-workers successfully prepared a series of nanosized Raney Ni catalysts with the same technology. 27 The obtained catalysts had high stability and selectivity (90%) for the hydrodeoxygenation (HDO) of guaiacol to cyclohexanol. Gas atomization as an efficient processing route that is widely used in industry to make powders in the field of powder metallurgy has also been applied to the preparation of an Ni− Al alloy.…”

“…In comparison with regular Raney Ni prepared by pyrometallurgical methods, the catalyst thus obtained had a narrow particle size distribution, which then generated a uniform pore size. Recently, Rong and co-workers successfully prepared a series of nanosized Raney Ni catalysts with the same technology . The obtained catalysts had high stability and selectivity (90%) for the hydrodeoxygenation (HDO) of guaiacol to cyclohexanol.…”

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.

“…Use of methanol as a hydrogen source is also reported for this conversion and it gave 54 % yield of cyclohexanol using Ni/CMK catalyst (Table 1, entry 2) [68] . Stable and reusable (nine cycles) mechanical alloyed nanoporous Ni (MA‐NP−Ni) catalyst was reported in high yield (90 %) of cyclohexanol from guaiacol (Table 1, entry 3) and showed similar catalytic activity for all reaction cycles [69] . Another catalyst, Ni/Nb 2 O 5 also displayed good catalytic activity to produce cyclohexanol in aqueous medium (Table 1, entry 4).…”

Lignin is one of the primary components of lignocellulosic biomass. It is an alternative and sustainable source for aromatic and cyclic hydrocarbons. Lignin is obtained in large quantities as a co‐product in sugar, paper‐pulp, and bioethanol industries. Hydrodeoxygenation/‐hydrogenation of lignin‐based phenolic compounds is an important route to synthesize new generation products. This review focuses on recent catalytic methods for selective conversion of phenolics into cyclohexa(nol/none/ne); which are precursors for emerging polymers and fuels. Furthermore, effect of metal catalysts, supports, and parameters on different reactions were discussed along with possible industrial applications of obtained cycloalkanes. In addition, limitations, advantages, and future scope of hydrodeoxygenation/‐hydrogenation of monolignols are also described.

An unsupported nanoporous platinum−iron bimetallic catalyst (PtFeNPore) was prepared with an electrochemical dealloying technique. Its structure and composition were characterized through various measurement methods, such as X-ray absorption fine structure (XAFS) and X-ray photoelectron spectroscopy (XPS). An intermetallic compound and iron oxide species were both found in the PtFeNPore catalyst. The nanoporous structure and Lewis acidity (caused by iron oxide species) of the PtFeNPore catalyst resulted in superior catalytic activity and high selectivity. The PtFeNPore-catalyzed hydrogenation of various halonitrobenzenes proceeded successfully under mild reaction conditions and produced good to excellent yields of the corresponding haloanilines with high selectivity. PtFeNPore can be recycled through magnetic separation easily and reused five times without significant deactivation.
