摘　　要：以Pt/N-COPs为催化剂,催化肉桂醛选择性加氢制备肉桂醇.采用三聚氰胺和三聚氰氯为原料,通过Buchwald-Hartwig反应合成含有三嗪环的共价有机聚合物,通过浸渍负载Pt制备Pt/N-COPs催化剂,用XRD、FT-IR和BET对其进行表征.结果表明,载体的富电子可以促进Pt很好分散在载体上.在肉桂醛选择性加氢制备肉桂醇的反应中,对催化剂的催化活性、动力学行为进行评价.结果表明,Pt/N-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/N-COPs.Covalent organic polymers containing triazine rings were synthesized by Buchwald Hartwig reaction with melamine and cyanuric chloride as raw materials.And then loaded Pt nanoparticles on the covalent organic polymers by immersion method at room temperature.Pt/N-COPs was characterized using X-ray diffraction(XRD),Fourier transform infrared spectrum(FT-IR),N2-physisorption.The characterization results show that the electron rich carrier can promote the higher dispersion of Pt on the carrier.In the selective hydrogenation of Cinnamaldehyde to cinnamyl alcohol,the catalytic activity and kinetic behavior of the catalyst were evaluated.The results show that Pt/N-COPs catalyst not only shows excellent catalytic activity,but also shows excellent C═O bond hydrogenation selectivity.
