The resistance of the Pd/C samples towards hydrogenation of the carbon support was studied in the temperature-programmed and isothermal regimes. Carbonaceous graphite-like material Sibunit was used as a carbon support. Pristine Sibunit was additionally graphitized via high temperature treatment (1900 °C) in an inert atmosphere <https://www.sciencedirect.com/topics/chemistry/inert-atmosphere>. Both initial and graphitized supports were subjected to oxidative treatment in order to increase the amount of surface functional oxygen-containing groups. Palladium (1 wt%) was supported using an aqueous solution <https://www.sciencedirect.com/topics/chemistry/aqueous-solution> of H2PdCl4. All the samples were characterized by a low-temperature adsorption <https://www.sciencedirect.com/topics/chemistry/adsorption> of nitrogen, transmission electron microscopy <https://www.sciencedirect.com/topics/chemistry/transmission-electron-microscopy>, and Raman spectroscopy. The graphitization procedure was found to decrease significantly the specific surface area <https://www.sciencedirect.com/topics/chemistry/specific-surface-area> of the support, while the oxidative treatment affects this parameter negligibly. Testing the Pd-containing samples in a hydrogen <https://www.sciencedirect.com/topics/chemistry/hydrogen> flow revealed the following order in accordance with amount of methane <https://www.sciencedirect.com/topics/chemistry/methane> released: Pd/iSib » Pd/iSib-ox > Pd/gSib > Pd/gSib-ox.
