Аннотация доклада:
Pyrolysis of sawdust impregnated with Pd(NO3)2 in inert atmosphere is an appropriate way to produce Pd/C catalysts containing nanoparticles of Pd0 (XPS data) in the narrow particle size range on the carbon support of biomorphic structure. Such systems are active in gas-phase hydrodechlorination of chlorobenzene in continuous flow system with packed bed of catalyst, and liquid-phase hydrodechlorination of polychlorinated benzenes. Pretreatment of sawdust by soaking in water, with or without sonification, and by hydrothermal water treatment provides significant increase of SBET (up to 225 m2/g) at a concurrent widening of Pd particle size distribution. Both the presence of alkali-earth metals in Pd/C due to the use of biotemplate, and modification with Co addition improve catalytic properties.
