title = "Structure effect of modified biochar in Ru/C catalysts for sugar mixture hydrogenation",
abstract = "This study deals with the production and activation of biochars and their use as supports for a series of ruthenium catalysts for hydrogenation of L-arabinose/D-galactose sugar mixture. The synthesized biochars differ in physicochemical properties and surface chemistry influencing ruthenium metal uptake and dispersion and as a consequence its catalytic behaviour. Selectivity exceeding 95% was observed for both hexitols. The catalytic performance of the prepared Ru supported catalysts is also compared to the already known Ru/activated carbon commercial catalyst.",

note = "Funding Information: Five ruthenium catalysts (2 wt % nominal loading) were prepared using the set of carbonaceous supports by wetness impregnation of an acetone solution of ruthenium (III) nitrosyl nitrate (Johnson Matthey; purity = 14.34%). In a typical preparation, dried biochar was deposited in a mortar and appropriate volume of 1·10−3 M metal precursor were mixed dropwise. Afterward, biochar was dried at 100 °C overnight and activated at 300 °C during 2 h under reductant atmosphere (1:1vol. N2/H2, 100 mL/min). The generated catalysts were labelled as Ru/Ccel, Ru/Ccel ZnCl2, Ru/Cvin, Ru/Cvin ZnCl2 and Ru/Cdarco. A commercial catalyst containing 4.6 wt% ruthenium on activated carbon (Ru/Ccomm, Degussa) was also included in the series.Financial support for this work was obtained from Spanish Ministerio de Ciencia e Innovaci{\'o}n (MICCIN) (Grant PID2020-113809RB-C32) and Junta de Andaluc{\'i}a via Consejer{\'i}a de Transformaci{\'o}n Econ{\'o}mica, Industria, Conocimiento y Universidades and its PAIDI 2020 program (Grant: P18-RT-3405) all co-financed by FEDER funds from the European Union.
