担载于Ａｌ_２Ｏ_３和ＺｒＯ_２上的Ｆｅ_２（ＣＯ）_９络合物的羰基在真空中极易脱附，在Ａｒ或Ｈ_２中２５０℃左右也可完全脱羰而成分散型催化剂．以ＺｒＯ_２为载体者在Ａｒ中低温下易发生表面歧化反应而生成ＣＯ_２，高温下生成少量ＣＨ_４．吸附于分散型催化剂上的ＣＯ在Ａｒ或Ｈ_２中均易发生岐化反应，以ＺｒＯ_２为载体者在Ｈ_２中发生加氢反应而生成ＣＨ_４，在ＣＯ加氢中其反应物除了大量ＣＯ_２外还有少量ＣＨ物．原位ＦＴ－ＩＲ谱表明以ＺｒＯ_２为载体者在Ｈｅ中或ＣＯ和Ｈ_２中均出现相当于多种中间物种的Ｃ－Ｈ振频带．根据实验结果提出了以ＺｒＯ_２为载体的Ｆｅ_２（ＣＯ）_９络合物在脱羰基过程中和在ＣＯ加氢反应过程中生成ＣＨ物种的机理．
The carbonyl group of Fe_2 (CO) _9 complex supported on Al_2O_3 and ZrO_2 can be easily desorbed in vacuum, and can be completely decarbonated at 250 ℃ in Ar or H_2. With ZrO 2 as carrier, it is easy to produce surface disproportionation reaction at low and medium temperature of Ar to generate CO 2, and generate a small amount of CH 4 under high temperature. The CO adsorbed on the dispersed catalyst is prone to occur the disproportionation reaction in Ar or H 2. Hydrogenation reaction takes place in H 2 with ZrO 2 carrier to generate CH 4. In addition to the large amount of CO 2, the reactants in CO hydrogenation A small amount of CH objects. In-situ FT-IR spectra showed that ZrO_2 as a carrier showed a C-H vibrational band corresponding to many intermediate species in He or CO and H_2. Based on the experimental results, the mechanism of the formation of CH species during the decarbonylation of Fe 2 (CO) _9 with ZrO_2 as support and the CO hydrogenation reaction was proposed.
