“…As part of our studies directed towards the development of new metal nanoparticles and new supported catalysts, we have focused our attention on the preparation, characterization and catalytic application of palladium nanoparticles supported on natural phosphate (NP). NP, being the first mining sector in the Moroccan kingdom, is a natural and low‐cost material that exhibits interesting properties such as ionic substitution ability, structural stability and high adsorption capacity, making it an attractive and cost‐effective catalyst for several chemical transformations.…”

We report the preparation of palladium nanoparticles supported on mesoporous natural phosphate (Pd@NP) using a wetness impregnation method. The prepared catalyst was characterized using various techniques. Furthermore, the reduction and preparation of the palladium nanoparticles was followed using UV–visible spectra. Based on the Scherrer equation, the crystallite size of the as‐synthesized palladium nanoparticles was 10.88 nm. The performance of the synthesized catalyst was investigated in the reduction of 4‐nitrophenol as a model substrate to 4‐aminophenol using NaBH4 as a hydrogen source. Moreover, catalytic reduction of various nitroarenes was studied and monitored using UV–visible spectroscopy and gas chromatography. The Pd@NP catalyst showed a high activity for the selected reaction and could be recycled.

“…The Fe 3 O 4 /CMC composite material was prepared by coprecipitating method with iron salt and CMC-Na. The Ni(0)-CMC-Na catalyst was obtained using the CMC-Na aqueous solution and the precursor NiCl 2 •6H 2 O, and the catalyst showed high efficiency for the hydrogenation of a variety of functionalized olefins at room temperature and moderate hydrogen pressures (Harrad et al, 2011). Based on the reported results, it is reasonable to speculate that CMC-Na could be applied into the construction of metal ion-organic ligand MPV catalyst for the conversion of furfural.…”

Functional use of biomass based on its structural properties is an efficient approach for the valuable utilization of biomass resources. In this work, carboxymethyl cellulose zirconium-based catalyst (Zr-CMC) was constructed by the coordination between the carboxylic groups in sodium carboxymethyl cellulose (CMC-Na) with transition metal Zr4+. The prepared catalyst was applied into the synthesis of furfuryl alcohol (FAL) by catalytic transfer hydrogenation of biomass-derived furfural (FF) using isopropanol as hydrogen donor. Both the preparation conditions and the reaction conditions of Zr-CMC catalyst were investigated and optimized. The results showed that Zr-CMC was efficient for the reaction with the FF conversion, FAL yield and selectivity reaching to 92.5%, 91.5 %, and 99.0%, respectively, under the mild conditions (90°C). Meanwhile, the Zr-CMC catalyst could be reused at least for five times without obvious decrease in efficiency, indicating the catalyst had excellent stability. With the advantages of sustainable raw materials, high efficiency, and excellent stability, the prepared catalyst is potential for application in the field of biomass conversion.

“…Impressively, fatty acids and sunflower oil could also be converted in high yields. Considering Ni catalysts, colloidally stabilized Ni nanoparticles were used for the selective hydrogenation of α,β‐unsaturated carbonyl compounds at room temperature and 4 MPa H 2 [14f] . In addition, supported systems such as the Ni‐phen@SiO 2 catalyst (4 mol% Ni) were developed to selectively convert substrates with different functional groups at 40 °C, 1 MPa H 2 [11e] .…”

The selective hydrogenation of functionalized olefins is of great importance in the chemical and pharmaceutical industry. Here, we report on a nanostructured nickel catalyst that enables the selective hydrogenation of purely aliphatic and functionalized olefins under mild conditions. The earth-abundant metal catalyst allows the selective hydrogenation of sterically pro-tected olefins and further tolerates functional groups such as carbonyls, esters, ethers and nitriles. The characterization of our catalyst revealed the formation of surface oxidized metallic nickel nanoparticles stabilized by a N-doped carbon layer on the active carbon support.
