Накратко на български

Метал-органичните рамки с два или повече метала се изследват като катализатори за провеждането на сложни химични реакции в една стъпка. Това помага за намаляване на разходите и енергията в индустриалните процеси чрез по-лесно отделяне и повторна употреба на материалите.

Rational design of novel heterometallic MOFs for their use in heterogeneous catalysis for cascade reactions

Our current industrial society is characterised by an extensive use of technology and mass production. Such a structure uses a tremendous number of industrial processes with large energy consumptions. One of the major challenges in the chemical industry is therefore to reduce processing costs through the development of more efficient catalytic industrial processes. In this context, heterogeneous catalysis plays a crucial role allowing an easy post-reaction separation and recyclability, which is translated in cost effectiveness. In fact, most of the high-temperature industrial processes have room for improvement in terms of effectiveness as well as use several numbers of steps in the process. A major breakthrough to tackle this issue arises from the design of multifunctional solid catalysts, since it is expected that bi/multi-functionalization achieve specific reactions in one single step thus noticeably reducing processing costs. The present hetero-MOF project proposed mixed-metal Metal-Organic Frameworks (MOFs) as suitable multi-functional structures for their implementation as superior heterogeneous catalysts. The project targets the direct synthesis of bi-metallic MOFs aiming to improve catalytic performances of the homo-metallic analogous. With this purpose, several goals are envisioned: i) The design and synthesis of new multi-metallic MOF structures. ii) The comprehensive physico-chemical characterisation of the hetero-MOFs. iii) The study of MOFs’ catalytic performances in model reactions.

Цел на проекта

The field of metal-organic frameworks (MOFs) is currently among the most extensively studied topics in chemistry given the large number of fascinating applications associated with the chemical versatility of MOFs. In particular, the use of MOFs as heterogeneous catalysts is an area that has attracted considerable attention since, in principle, the ideally suited architectures of MOFs can present catalytically active sites spatially arranged. With the expansion of this area, a new emergent class of heterometallic metal-organic frameworks (hetero-MOFs) has recently been considered for the study of an important type of reactions from an industrial point of view in which two or more individual reactions are carried out in a single step (""tandem"" or ""cascade"" reactions). However, the synthetic approach for the preparation of these hetero-MOFs has been mainly conducted by post-synthetic replacement of ions with the same oxidation state, with lack of control over the final composition.The project herein described focus on the design and preparation of novel hetero-MOFs with enhanced stability to perform as superior heterogeneous catalysts. With this purpose, a reasonable straightforward method is proposed, consisting in the low temperature synthesis of hetero-MOFs using pre-designed heterometallic secondary building units (SBUs) as starting materials. The main challenge lies in the control of the metal stoichiometry based on cations with different oxidation states and therefore very different chemical reactivities. The catalytic performance of the novel hetero-MOF materials will be tested during a secondment of excellence already established in the hetero-MOF project.""
