ABSTRACT:

H2PtCL6 was used for the preparation of Pt/Al2O3 by thermal treatment at 380?C then, reduction by hydrogen. Dipersion of Pt/Al2O3 much higher when the pretreatment of H2PtCl was done in oxygen atmosphere at 380?C then in helium atmosphere. The intremediates formed through the investigated thermal pretreatment process were PtCl6 was done at 260?C and 380?C respectively when helium was the atmosphrere fo pretreatment while Pt(OH)Cl3, and probadly PtO2 were obtained at the above temperature when oxygen was the atmosphere of the pretreatment.
