研究了水热法制备的一系列nio - ceo2混合氧化物催化剂对N2O的分解作用。结果表明，在NiO催化剂中加入ceo2可显著提高N2O的分解活性。ceo2的引入抑制了NiO相的结晶，导致了高的比表面积。特别是NiO和ceo2的共存在表现出协同效应，有助于形成稳定的Ni2+活性位点。这些因素共同解释了nio - ceo2混合氧化物催化剂分解N2O的高活性。
A series of NiO-CeO2mixed oxide catalysts prepared by the hydrothermal method were investigated for the decomposition of N2O. It was found that the addition CeO2to NiO catalyst leads to a noticeable enhancement of the activity for the decomposition of N2O. The introduction of CeO2inhibited the crystallization of the NiO phase, leading to the high surface area. In particular, the co-presence of NiO and CeO2exhibited a synergetic effect, which contributes to forming the stabilized Ni2+active sites. All of these factors, collectively, accounted for the high activity of NiO-CeO2mixed oxide catalyst for the decomposition of N2O.
