摘要:
采用自组装法,以廉价Ce(NO3)3·6H2O为铈源,1,2-环己二胺缩5-甲基水杨醛为配体,制备了功能化二维Ce-MOFs(Ce-salen-2D)。进一步以Ce-salen-2D为模板,通过配位辅助浸渍(Coordination-Assisted Synthesis,CAS)方法,合成了高分散的CeO2负载Ni催化剂(Ni@CeO2-CAS),对合成的Ni@CeO2-CAS 催化剂进行了XRD,TEM,BET,CO化学吸附测试以及Raman表征和甲烷干重整(DRM)反应性能测试。结果表明与传统浸渍法(IWI)制备的催化剂(Ni/CeO2-IWI)相比,Ni@CeO2-CAS在DRM反应中显示出较高的催化活性以及较高的催化稳定性。
Abstract:
The preparation of functional two dimensional Ce-MOFs(Ce-salen-2D)via a self-assembly method using a low-cost of Ce(NO3)3·6H2O as the Ce precursor, N,N'-bis(salicylidene)-1,2-cyclohexanediamine as organic ligand was synthesized. Furthermore, the Ce-salen-2D was selected as template, a highly dispersed CeO2 supported Ni catalyst was synthesized(Ni@CeO2-CAS)through a coordination-assisted synthesis(coordination-assisted synthesis, termed as CAS), and characterized by the XRD, TEM, BET, CO chemsorption and Raman, as well as applied for the drying reforming of methane with CO2. In comparison with classic catalyst(Ni/CeO2-IWI)prepared by the impregnation method, the results demonstrated that the Ni@CeO2-CAS exhibited higher catalytic activity and good catalytic stability.
