Glucose–Carbon Hybrids as Pt Catalyst Supports for the Continuous Furfural Hydroconversion in Gas Phase

Glucose–carbon hybrids were synthetized with different carbon materials, namely nanotubes, reduced graphene oxide, black and activated by a hydrothermal treatment. These used as Pt-supports (1 wt.%) for the furfural (FUR) hydroconversion in gas phase at mild operating conditions (i.e., P = 1 atm T 200 °C). The physicochemical properties (porosity, surface chemistry, Pt-dispersion, etc.) analyzed techniques. presented apparent areas between 470–500 m2 g?1, neutral character good distribution of small Pt-nanoparticles, some large ones octahedral geometry being also formed. Catalytic results showed two main reaction pathways: (i) FUR hydrogenation to furfuryl alcohol (FOL), (ii) decarbonylation furane (FU). products depended on temperature, FOL or FU mainly produced low (120–140 °C) high temperatures (170–200 °C), respectively. At intermediate temperatures, tetrahydrofurfuryl was formed secondary hydrogenation. is structure-sensitive reaction, rounded-shape Pt-nanoparticles producing FU, while Pt-particles favor formation FOL. Pt-catalysts supported glucose–carbon better catalytic performance temperature than catalyst prepared reference material, no deactivation identified after several hours stream.
