“…Sibunit is a synthetic carbon composite, which is produced by pyrolysis of light hydrocarbons on a granulated carbon black followed by steam activation at 973-1123 K of the composite obtained. 54,55 A sponge-like system including meso-and macropores whose dimensions depend on the dispersion of the initial carbon black is formed.…”

aThe aqueous phase reforming (APR) of xylitol was studied over five Pt/C catalysts. The correlation between physico-chemical properties of the catalysts and catalytic performance was established. The Pt/C catalysts have different textural properties as well as different mean Pt cluster sizes and surface acidity. The average Pt cluster size was investigated by means of CO chemisorption as well as by TEM.The reaction was found to be structure sensitive and TOF linearly increases with increasing average Pt cluster size in the studied domain. The catalysts which possess higher surface acidity favoured higher rates of hydrocarbon production. On the contrary the Pt/C materials with lower acidities generated hydrogen with high selectivity and TOF.

“…Moreover, the textural characteristics of the Sibunit carbon materials, such as surface area, pore size distribution and the agglomerate size and shape, can be varied in a wide range by choosing an appropriate template and synthesis conditions [11,12]. A number of Sibunit materials with widely varying structural parameters were recently used for the preparation of the PtRu catalysts for anode in the direct methanol fuel cells [9] and Pt/C catalysts for the cathode in H 2 /O 2 PEMFC [10].…”

Sibunit Carbon‐Based Cathodes for Proton‐Exchange‐Membrane Fuel Cells

Preparation, characterisation and evaluation of a novel cathode catalyst for H2/O2 PEMFC – 40 wt.‐% Pt/Sibunit 1562P carbon – is presented. The performance of the cathodes based on the latter material is compared to that of a widely used commercially available reference material – 40 wt.‐% Pt/Vulcan XC 72R – Hispec 4000 (Johnson Matthey, UK). It has been found that the mass activity of the 40 wt.‐% Pt/Sibunit 1562P catalyst exceeds that of a commercial benchmark by a factor of 2 due to a better dispersion of the Pt metal realised in the Sibunit – supported catalyst. Mass transport properties of the two catalysts studied are virtually equal.

Laser electrodispersion (LED) of metals is a promising technique for the preparation of heterogeneous catalysts as an alternative to wet impregnation of supports with the corresponding salt solutions. The LED technique can be used to deposit highly active chlorideand nitrate-free metal nanoparticles onto carbon or oxide supports. We report preparation and properties of new Ni-, Pd-, and Au-containing alumina-supported catalysts with low metal loadings (10 -3 -10 -4 % mass) and their comparison with the previously studied carbon (Sibunit) supported systems. The catalysts demonstrate high stability and extremely high specific catalytic activity (by 2-3 orders of magnitude higher than for traditional catalysts) in the gas-phase hydrodechlorination (HDC) of chlorobenzene (CB).
