二草酸根二氧钒酸铵配合物在氢气中热分解机理研究

Studies of Thermal Decomposition Mechanism of Ammonium Dioxovanadium(V) Bisoxalate Dihydrate in Hydrogen Atmosphere

用程序升温气相色谱法，配合ＥＳＲ，ＩＲ等手段，研究了二草酸根二氧钒酸铵配合物在氢气气氛中的热分解机理，并讨论了负载型体系中，载体（γ－Ａｌ２Ｏ３、ＳｉＯ２、ＭｇＯ）对配合物热分解的影响．

The thermal decomposition of (NH 4) 3VO 2(C 2O 4) 2·2H 2O supported γ-Al 2O 3,SiO 2,MgO and corresponding unsupported compounds in hydrogen atmosphere is investigated by temperature programmed decomposition gas chromatograph method supplemented by ESR, IR, DIA-TG and chemical analysis, etc. A reasonable mechanism of the thermal decomposition is proposed.
