The effect of oxidative treatment of thermal grade T900 nanoglobular carbon with a HNO3 solution (20 wt.%) with a duration of 0.5 to 4 h on the structure and functional properties of the carbon surface of the supported palladium catalyst was investigated. As a result of this treatment the pore structure of the carbon material remains virtually unchanged, but its surface becomes significantly enriched with acidic oxygen-containing groups; their concentration depends on the intensity of the formation and destruction of amorphous carbon and other disordered carbon structures. Changes in the functional properties of the T900 surface caused by oxidative treatment lead to an increase in the dispersion of palladium nanoparticles in the Pd/T900 system. Varying the duration of oxidative treatment of T900 affects the catalytic properties of the Pd/T900 system in the aqueous-phase hydrogenation of furfural (423 K, 3.0 MPa). An increase in the concentration of oxygen-containing groups on the surface of T900 during oxidative treatment results in an increase in catalytic activity and selectivity in the formation of 4-oxopentanal and 5-hydroxypentan-2-one.
