Abstract

Abstract: Nanoscale Pd(OH)₂was prepared by azeotropic distillation process for the first time, and its structure was characterized by high resolution TEM, DLS and UV-V is absorption spectrum. The results show that the particle size of the prepared Pd(OH)₂is of 37.3nm and the particles are facecentred cubic polycrystalline. The prepared Pd(OH)₂nanosized particles show a higher catalytic activity than 20%Pd(OH)₂/C in the catalytic hydrogenolysis of 2,4,6,8,10,12-hexabenzyl-2,4,6,8,10,12-hexaazaisowurtztane(HBIW).

Key words: Palladous hydroxide, Nanosized particles, Structure characterization, Catalytic hydrogenolysis
