determined. The BET surface area of Pt/TiO 2 catalyst (60.2 m 2 /g) is slightly lower than the titania support (61.5 m 2 /g) which may be attributed to a partial blockage of the porestructure of the support by metallic crystallites. This behavior is in

activity of the catalyst. The combination of secondary factors such as surface area, poresstructure, point of zero charge, ratio S/Rh, detailed composition (impurities, additives), acidobasic properties and crystallinity also plays an important role. It is

The above interpretation is confirmed by pore size distribution diagrams ( Fig. 6 ) where one can see that the two samples have no uniform porestructure and include

the catalytic activity of Ru/AC.
The performance of AC was associated with the surface and porestructure. According to the data in Table 3 , Ru/AC calcined at 900 °C shows the highest S BET and pore volume of 1,081.44 m 2 /g and 0.45 cm 3
