摘　　要：该研究以Pt/DPCC-COPs为催化剂,催化肉桂醛选择性加氢制备肉桂醇。采用2,5-二氨基吡啶和三聚氰氯为原料,通过Buchwald-Hartwig反应合成了含有三嗪环的共价有机聚合物DPCC-COPs,通过等体积浸渍负载Pt制备Pt/DPCC-COPs催化剂,用X射线衍射仪(XRD)和傅里叶变换红外光谱(FT-IR)对其进行表征。结果表明载体的富电子性能可以促进Pt很好的分散在载体DPCC-COPs上。在肉桂醛选择性加氢的反应中,对催化剂的催化活性、动力学行为进行了评价。研究结果表明,Pt/DPCC-COPs催化剂不仅表现出优异的催化活性,而且表现出优异的C=O键加氢选择性。Selective hydrogenation of cinnamaldehyde to cinnamyl alcohol over Pt/DPCC-COPs was studied.Covalent organic polymers containing triazine rings were synthesized by Buchwald Hartwig reaction with 2,5-diaminopyridine and cyanuric chloride as raw materials.And then Pt nanoparticles were loaded on the covalent organic polymers by immersion method at room temperature.Pt/DPCC-COPs was characterized using X-ray diffraction(XRD)and Fourier transform infrared spectrum(FT-IR).The characterization results showed that the electron rich carrier could promote the higher dispersion of Pt on the carrier.In the selective hydrogenation of cinnamaldehyde,the catalytic activity and kinetic behavior of the catalyst were evaluated.The results showed that Pt/DPCC-COPs catalyst not only showed excellent catalytic activity,but also showed excellent C=O bond hydrogenation selectivity.
