| Popis: | NiO layers were deposited by metal-organic chemical vapor deposition using bis-(ethylcyclopentadienyl) nickel (EtCp)2Ni and oxygen or ozone. As a continuation of kinetic study of NiO MOCVD the gas-phase, transformations of (EtCp)2Ni were studied in the temperature range of 380–830 K. Time of reactions corresponding to the residence time of the gas stream in hot zone of the reactor was about 0.1 s under conditions studied. The interaction of (EtCp)2Ni with oxygen started at 450 K and its conversion rate reached the maximum at 700 K. The interaction of (EtCp)2Ni with ozone started at 400 K and its conversion rate reached the maximum at 600 K. Transformations of the gas phase with the temperature in the reaction zone were studied, the model reaction schemes illustrating (EtCp)2Ni transformations in the reaction systems containing oxygen and ozone have developed. In the reaction system (EtCp)2Ni–O2–Ar the main gas-phase products at 380–500 K were CO, CO2, HCO, C2H5OH, CpCOOH, and CpO. Formation of the C2H2O, C3H4O, and C5H8O was found at 630–830 K. The same gas-phase species, (C4H3O)2Ni and dialdehydes was formed in the reaction system (EtCp)2Ni–O3–O2–Ar. |
