“…A ruthenium supported on carbon nanofibers (Ru/CNF) catalyst, previously used to hydrolytically hydrogenate cellobiose (Frecha et al, 2019), was employed in this work. It consists of Ru nanoparticles of around 1.2 nm supported on CNF, resembling a fishbone structure (observed by Transmission Electron Microscopy), with a Ru content of 0.4 wt% (calculated by Inductive Coupled Plasma).…”

“…Also, the effect of the processing conditions is not yet well understood using actual biomass. In previous work in our research group, Frecha et al (2019) used a 0.4 wt% Ru/CNF catalyst for the hydrothermal hydrogenation of cellobiose (a cellulose model compound). The effect of the processing time (0−3 h) was analysed on the cellobiose conversion and reaction products distribution at 180 °C employing an initial H 2 pressure of 4 bar.…”

Production of linear α-olefins from renewable sources is gaining increasing attention because it allows the transition from the current petrochemical synthesis route to a more sustainable scenario. In this work, we describe the synthesis and characterization of an innovative catalyst based on a di-μ-chloro-bisĳpalladiumĲII) anthranilate] complex highly dispersed by incipient wetness impregnation over acyl chlorinated carbon nanofibers. The subnanometric dispersion of the metal complex allowed higher catalytic efficiency for the selective decarbonylation of stearic acid to 1-heptadecene as compared to the reference homogenous catalyst. The best catalytic performance (90 mol% selectivity, 71 mol% conversion, and TON = 484) was achieved under mild reaction conditions (atmospheric pressure, 140°C) with a Pd loading in solution of 0.14 mol%. The post-mortem catalyst characterization and the recyclability tests evidenced the high stability of the catalyst. The highly dispersed catalyst developed in this work provides new opportunities in the rational design of more efficient catalytic systems for the sustainable transformation of fatty acids.

“…As a rule, metal nanoparticles fixed on a carbon support are obtained through a separate stage of metal deposition (e.g., impregnation with a solution of metal compounds, followed by reduction, laser deposition or deposition from the vapor phase) [18,19]. In [20], we proposed a procedure for the simultaneous production of metal nanoparticles and a carbon support, in which a mixture of a carbon-containing precursor and metal compounds is subjected to heat treatment.…”

A procedure is proposed for synthesizing monometallic (Co, Pd) and bimetallic Co–Pd nanoparticles immobilized in a carbon support based on pyrolyzed chitosan. A feature of the procedure is the simultaneous formation of metal nanoparticles and a carbon support during the heat treatment of a precursor based on a joint solution of a polymer and metal compounds under the effect of IR radiation. The phase composition, morphology of samples, and structural features of the carbon support are shown, depending on the nature of the metals that are used.
