摘要
Ｃｏ（ＣＯ）３ＮＯ吸附进入Ｙ分子筛超笼，笼中不同交换阳离子对其吸附和分解起不同作用．研究不同交换阳离子Ｙ分子筛上Ｃｏ（ＣＯ）３ＮＯ的吸附和热分解发现，吸附金属络合物部分脱羰基或脱亚硝基，并伴有少量吸附物种的脱附．ＮａＹ上的热分解产物主要为金属钴；ＮｉＹ，尤其是ＣｕＹ上，阳离子和吸附物种作用较强，甚至发生电子转移。
The adsorption and thermal decomposition of Co(CO)_3NO on the Yzeolites containing cations of Na^+, Ni^2+ and Cu^2+ were investigated by gravimetric, lowtemperature nitrogen adsorption and electron spin resonance techniques. Co(CO)_3NO molecules can be introduced into the supercages of Y zeolites. The cations of different properties in the zeolites significantly influence the behaviors of the adsorption of Co(CO)_3NO on the zeolites. For NaY and NiY, the metal complex species partially decompose upon adsorption on the zeolites and heating accompanied, meanwhile, the desorption. After complete decomposition, metallic cobalt is the main product on NaY zeolite. On CuY and NiY, however, the adsorbed metal complex species strongly interact with the cations in the zeoltie, the product of decomposition is the mixture of metallic cobalt and cobalt oxide.
