有序双组分氧化物CoO-NiO/MCM-41催化剂的合成与表征

Synthesis and Characterisation of CoO-NiO/MCM-41 Bimetallic Oxide Catalysts

在碱性条件下用组装的方法得到了高负载量,均匀分布的CoO-NiO负载型MCM-41介孔材料,并采用XRD、BET、HREM等测试手段对样品进行了分析,结果表明,CoO,NiO双组分氧化物已成功地组装进入了MCM-41的有序孔道,在CoO,NiO组装过程中,CoO,NiO含量分别为7.53wt％和5.94wt％时,介孔材料的有序结构没有遭到破坏。

MCM-41 material assembled with bimetallic cobalt and nickel oxides was synthesized under basic condition. The samples were characterized by XRD, HREM and BET techniques. Results showed that CoO and NiO bimetallic oxide can be introduced into the ordered pores of MCM-41 successfully. Odered structure of mesoporous materials wasn't destroyed when loading contents of CoO and NiO were 7.53wt% and 5.94wt%, respectively. It is expected that highly dispersed CoO and NiO in the pore channels of well-ordered MCM-41 structure are very potential for advanced catalytic application.
