摘要
基于亚胺键合成一系列(金属)卟啉亚胺凝胶。这些亚胺气凝胶是由纳米粒子基元互相连接而成的海绵状多孔网络结构,拥有高比表面积和大孔体积。引入金属离子(钯(II)、镍(II)、锰(III)、铁(III)和锡(IV))的亚胺凝胶尽管密度增大,但其对各种气体(如:二氧化碳)的吸附能力仍得到提升。在金属离子中,钯(II)的CO_2吸附能力和相应的等量吸附热是最高的。由于具有独特的层次孔结构和金属中心的存在,这些凝胶在催化方面存在潜在的应用。结合微流体技术,成功把Pd-tapp-A4凝胶负载到毛细管内壁,组装成微流反应器。
A series of(metallo)porphyrin imine gels have been synthesized based on imine chemistry, which have sponge-like porous networked structures consisting of interconnected nanoparticles with hierarchical porosity. The aerogels have high specific surface areas and large pore volumes. The impregnation of various metal ions(Pd(II), Ni(II), Mn(III), Fe(III) and Sn(IV)) enhances the uptake capacity of various gases(e.g., CO_2) despite their higher densities. Among the metal ions, Pd-tapp-A4 aerogel is the best to increase the adsorption capacity and the isosteric heat of CO_2 adsorption. The gels show potential applications in catalysis since their unique hierarchical porosity and the availability of metal centers. In combination with microfluidic technology, a catalytic gel capillary reactor has been assembled with the Pd-tapp-A4 gel supported on the inner surface of a functionalized capillary.
