Накратко на български

Металоорганичните рамки с манган и мед се тестват като катализатори за превръщане на въглеродния диоксид в метанол. Това помага за намаляване на вредните емисии в атмосферата и създаване на устойчиви горива и химикали.

Metallolinker-Functionalized MOF Catalysts for CO2 Hydrogenation

One of the main challenges of the 21st century is to reduce CO2 emissions in the atmosphere. To overcome this problem, fossil fuels can be replaced by renewable energy sources. Methanol is one of the sustainable key compounds that can be directly used as a low-density fuel or as a feedstock for valuable chemicals. To date, efforts to perform CO2 hydrogenation to methanol under mild reaction conditions have not achieved high enough selectivity at reasonable conversion values. Heterogeneous catalysts are robust and easy to recover but usually yield low selectivity due to the difficult control of the active sites. In contrast, homogeneous catalysts feature well-defined active sites amenable to logical optimization and selectivity design, but inefficient catalyst recovery and decomposition are huge shortcomings for industrial implementation. A promising strategy to combine benefits from both approaches is to immobilize well-defined catalysts on solid porous materials, such as metal-organic frameworks (MOFs). TUNEMOF’s goal is the preparation of functionalized MOFs bearing earth-abundant metals (Mn and Cu) as catalysts for CO2 hydrogenation to methanol. In addition, TUNEMOF aims to gain insight into the key steps of the catalytic cycle, identifying the potential key intermediates and processes of catalyst deactivation.

Цел на проекта

One of the main challenges of the 21st century is the reduction of CO2 emissions to the atmosphere, for which replacing fossil fuels with renewable energy sources will help. Methanol is a sustainable key compound that can be directly used as a low-density fuel or as a feedstock for valuable platform chemicals. To date, efforts to perform CO2 hydrogenation to methanol under mild reaction conditions have not achieved high enough selectivity at reasonable conversion values. Heterogeneous catalysts are robust and easy to recover but usually yield low selectivity due to the difficult control of the active sites during synthesis. In contrast, homogeneous catalysts feature well-defined active sites amenable to logical optimization and selectivity design, but inefficient catalyst recovery and decomposition are huge shortcomings for industrial implementation. TUNEMOF proposes to overcome these drawbacks by developing metallolinker-functionalized MOFs bearing earth-abundant metals (Fe and Mn). The immobilization of the molecular-based catalyst center will promote the metal-ligand cooperation and the secondary linker assistance will prevent the deactivation of the catalyst. Meeting this strategy with low-cost metal-based catalysts is a significant added value. TUNEMOF integrates the experience of the researcher in organometallic chemistry, the excellence of Prof. Olsbye’s group (University of Oslo) in applied chemistry of porous materials, the experience in catalytic testing of homogeneous systems of Prof. Beller (LIKAT, secondment), and in spectroscopic analysis and techno-economic assessment of Haldor Topsøe (non-academic placement). This synergy provides a unique networking platform to diversify the researcher’s individual competences and to promote the interdisciplinary and inter-sectorial transfer of knowledge. The complete training gained from the development of TUNEMOF will promote the professional career of the applicant to become a leading independent researcher.
