项目摘要
Catalysts play a crucial role in chemistry, as they increase the rate of reaction by lowering the activation energy, allowing the formation of compounds that otherwise will not form promptly. Typical examples are the production of ammonia, which is a process that needs to be catalysed by iron, or the production of biofuels. The improvements of catalytic processes not only help chemists and engineers to increase the efficiency of reactions, but also to reduce waste products, generating a massive environmental impact. This is especially true if we can design and synthesise new catalysts that produce alternative fuels in a more efficient way. This will be beneficial from both the economic and the social point of view, as we can reduce the cost of sustainable fuels and, at the same time, the exploitation of natural resources such as fossil fuel. The two most common catalysed reactions are known as homogeneous, where the catalyst can be dissolved in the media, and heterogeneous, where it is insoluble. Homogeneous catalysts are sometimes more active but their separation and reutilisation requires more energy and effort, whereas the heterogeneous ones are easily removed and recycled from the reaction by simple filtration. They can be further classified as acid, neutral or basic (alkaline), according to the nature of their active sites (i.e. where the catalytic reaction happens). Although alkaline catalysed reactions have been less investigated than their acidic counterparts, in recent years they have become more attractive as they are suited for the efficient production of biodiesel, as a sustainable and renewable source of fuel. This research project will focus on the design and synthesis of novel basic heterogeneous catalysts based on Polymers of Intrinsic Microporosity (PIMs). PIMs are materials with porosity arising from the inefficient packing of their polymeric structure in the solid state, which leaves voids of nano-dimensions. They can be used for a wide range of applications, including gas separation, gas storage and catalysis. Porosity represents a great advantage for a heterogeneous catalyst, as it forces the reaction to occur in a close environment, such as the surface of a pore, forcing the components of the reaction to be in much closer contact. Because of this advantage, PIMs have been previously used in heterogeneous catalysis but only by incorporating in the material active metal ions, which is not ideal as the presence of the metal makes them more expensive and less environmentally friendly. Recently, I introduced and patented a new class of PIMs based on a core known as Tröger's base (TB). They combine the high porosity of PIMs with the presence of two basic (alkaline) nitrogens. Attempts have been made to use TB cores by grafting them into pre-made polymeric materials, but this procedure leads to loss of catalytic material (known as leaching) during its recycling from the reaction media. I recently reported the synthesis of a network (insoluble) PIM exclusively made exclusively via TB formation, which showed great potential for heterogeneous catalysis, especially because the active site (TB) is an integral part of the material, and not simply grafted onto it. The project aims to the synthesis of new TB-PIMs to be used to catalyse biomass conversion (i.e., from waste biomass to make sustainable fuels) along with other environmentally and commercially important reactions. The improved production of biodiesel is not the only significant reaction where these novel polymers can be employed. The polymers will also be tested for the conversion of by-product created during the biodiesel synthesis into more reactive compounds, and for the conversion of CO2 into more useful products. Last but not the least, the polymers can be further turned into new materials for more efficient anion-exchange resins, a class of materials that can be used for purification of water and removal toxic metal from liquid waste.
催化剂在化学中起着至关重要的作用,因为它们通过降低活化能来提高反应速率,从而形成否则不会迅速形成的化合物。典型的例子是氨的生产,这是一个需要铁催化的过程,或者是生物燃料的生产。催化过程的改进不仅有助于化学家和工程师提高反应效率,还可以减少废物,产生巨大的环境影响。如果我们能够设计和合成新的催化剂,以更有效的方式生产替代燃料,这一点尤其正确。从经济和社会的角度来看,这都是有益的,因为我们可以降低可持续燃料的成本,同时减少对化石燃料等自然资源的开采。两种最常见的催化反应被称为均相反应,其中催化剂可以溶解在介质中,以及非均相反应,其中催化剂不溶于介质中。均相催化剂有时活性更高,但它们的分离和再利用需要更多的能量和努力,而非均相催化剂很容易通过简单的过滤从反应中除去和回收。它们可以根据其活性位点的性质(即催化反应发生的地方)进一步分为酸性,中性或碱性(碱性)。虽然碱性催化反应的研究比酸性反应少,但近年来它们变得更具吸引力,因为它们适合于生物柴油的有效生产,作为可持续和可再生的燃料来源。本研究计划将集中于设计和合成基于固有微孔聚合物(PIM)的新型碱性非均相催化剂。PIM是具有多孔性的材料,其多孔性是由于其聚合物结构在固态下的低效堆积而产生的,这留下了纳米尺寸的空隙。它们可用于广泛的应用,包括气体分离,气体储存和催化。孔隙率对于非均相催化剂来说是一个很大的优势,因为它迫使反应在封闭的环境中发生,例如孔隙表面,迫使反应组分更紧密地接触。由于这一优点,PIM以前曾用于多相催化,但仅通过在材料中掺入活性金属离子,这并不理想,因为金属的存在使它们更昂贵且不环保。最近,我推出了一种新的PIM,并获得了专利,这种PIM基于一种称为Tröger's base(TB)的核心。它们联合收割机了PIM的高孔隙率和两种碱性氮的存在。已经尝试通过将TB核接枝到预制的聚合物材料中来使用TB核,但是该过程导致催化材料在其从反应介质中再循环期间的损失(称为浸出)。我最近报道了一种网络(不溶性)PIM的合成,该网络(不溶性)PIM完全通过TB形成来制造,这显示出用于多相催化的巨大潜力,特别是因为活性位点(TB)是材料的组成部分,而不是简单地接枝到其上。该项目旨在合成用于催化生物质转化的新TB-PIM(即,从废弃生物质中制备可持续燃料)沿着其它环境和商业上重要的反应。生物柴油生产的改进并不是可以使用这些新型聚合物的唯一重要反应。还将测试聚合物将生物柴油合成过程中产生的副产物转化为更具反应性的化合物,以及将CO2转化为更有用的产品。最后但并非最不重要的是,聚合物可以进一步转化为更有效的阴离子交换树脂的新材料,这类材料可用于净化水和从液体废物中去除有毒金属。
