摘　　要：以不同孔洞尺寸及不同中心离子的纳米孔洞金属-有机骨架材料M_3(BTC)_2(H_2O)x(M=Cu~Ⅱ,Zn~Ⅱ,Co~Ⅱ,Ni ~Ⅱ,BTC=benzene tricarboxylic acid苯三甲酸)为催化剂,采用动力学方法,讨论其对p-苯二酚和o-苯二酚的选择性催化氧化性能.重点考察了催化剂孔洞尺寸,骨架中心离子,催化反应介质,反应温度对催化选择性的影响,以期对MOFs材料的选择性催化动力学方面有比较全面的认识.In this paper, selective oxidation of o, p-dihydroxybenzene catalyzed by metal organic frameworks Ma （ BTC）2 （ H2O） x （ M = Cu^Ⅱ, Znn, Co^Ⅱ, Ni^Ⅱ , BTC = benzene tricarboxylic acid） with different metal active centers and various pore sizes, have been studied. Catalytic selectivity of these MOFs under different conditions, such as temperature, reaction medium, pore size of metal organic framework materials, was studied by catalytic kinetic method. The aim of this study was to have a more comprehensive understanding of the selective catalytic kinetics of MOFs.
