Advanced green approaches for the synthesis of NiCu-containing catalysts for the hydrodeoxygenation of anisole

Metal@hollow carbon sphere nanoreactors for sustainable biomass and CO2valorization

“…The hydrodeoxygenation (HDO) process generally involves a combination of different reactions such as dehydration, hydrolysis, decarbonylation and hydrogenation, exhibiting signicant advantages such as high efficiency in the elimination or reducation of oxygen content as well as preservation of the carbon number in the product. 171,[185][186][187] These reactions generally take place at different reaction sites, and multiphase catalysts containing both metal sites (monometallic and bimetallic sites) and active acidic sites on a carrier, which are oen used to suit the specic target reaction. 188,189 However, metals are prone to sintering and leaching during catalysis, solid acid supports are subject to phase changes and loss of surface area, in addition to the condensation or polymerization of C]O or C]C bonds within oxygenated compounds that tend to occur at high temperatures, leading to carbon deposition on the catalyst.…”

Anisole Hydrodeoxygenation over Nickel-Based Catalysts: Influences of Solvent and Support Properties

“…A number of catalyst supports have been investigated to enhance catalyst performance. ,− Activity of a catalyst during a HDO reaction is greatly influenced by the acidity and pore structure of the support. − In comparison to metal-microporous support catalysts, metal-mesoporous support catalysts showed remarkable performances in the HDO of bio-oil. This was attributed to the improved diffusion properties and enhanced metal–support interactions. , For instance, in the HDO of guaiacol using nickel-based bifunctional catalysts, mesoporous Ni/HBeta was more selective to aromatics than microporous Ni/ZSM-5 .…”

The Role of Metal and Acid Sites in the Liquid‐phase Hydrodeoxygenation of Lignin‐derived Phenolic Dimers

“…The first category of model molecules consists of phenolic monomers such as guaiacol, [29–34] anisole, [35–40] cresol, [41–46] and phenol [47–54] that contain hydroxyl and/or methoxy groups attached to the aromatic ring. But dimeric aryl ethers such as benzyl phenyl ether (BPE), [55–69] 4‐(benzyloxy) phenol (4‐BOP), [52,63,69–72] phenethoxybenzene (PEB), [56,57,61,70,73–77] 2‐phenoxy‐1‐phenylethanol (PP), [64,78–84] and diphenyl ether (DPE), [56,57,62,63,70,85–89,89–100] are more representative of the α‐O‐4, β‐O‐4, and 4‐O‐5 ether linkages of lignin structure (Figure 2).…”
