Накратко на български

Нови материали от ковалентни органични рамки с метални центрове се тестват като катализатори за разлагане на вода и превръщане на въглеродния диоксид в мравучна киселина. Те помагат за създаването на по-евтини и устойчиви горива, като заменят скъпите благородни метали с достъпни преходни метали.

New Heterogeneous Catalyst Materials for Hydrogenation of CO2 to Formic Acid: Metallophthalocyanine-Based 2D- and 3D Covalent Organic Frameworks

The aim of the project was to develop a toolbox of metallophthalocyanine (MPc) building blocks as catalytically active single sites and linkers for the preparations of different 2D and 3D covalent organic framework (COF) materials. By developing single atom catalyst materials, the utilization of the metal catalyst can be maximized, decreasing the amount of critical raw materials used. The developed materials were investigated for their electrocatalytic activity towards oxygen evolution reaction (OER). It is an important anodic half-reaction in electrochemical processes, such as water splitting and CO2 reduction. Water splitting, producing oxygen and hydrogen, is a cornerstone in transforming our fossil fuel based society towards the use of more sustainable chemicals and fuels in the future. However, OER is the rate limiting electrochemical reaction in water splitting due to its sluggish kinetics, and therefore, the development of more active and stable electrocatalysts is a key challenge. Although noble metal oxides, such as RuO2 and IrO2, have been demonstrated to have high electrocatalytic activities towards the OER, the high price and scarcity of these materials are the major bottlenecks for their practical applications. Therefore, it is of great importance to develop OER electrocatalysts that are efficient, stable and low-cost, and to this end, earth-abundant transition metal-based (eg. Fe, Ni, Co) catalysts are of high interest.

Цел на проекта

In CO2COFs project we will meet the world’s need for new heterogeneous catalyst materials for catalytic CO2 hydrogenation to formic acid (FA) by developing novel metallophthalocyanine (MPc)-based covalent organic frameworks (COFs) with high crystallinity and large surface area for renewable hydrogen storage in formic acid (FA). Althought heterocatalytic CO2 hydrogenation to FA is one of the most promising conversions, relatively few catalytic materials have been reported for this transformation. Furthermore, there are many studies of the development of the homogeneous catalyst for CO2 hydrogenation to FA, but heterogenization of homogeneous Ru complexes by incorporating them onto supporting material is essentially unexplored. In CO2COFs project we will answer the demand by synthesizing MPc-based 2D- and 3D COFs which are highly crystalline materials offering a defined porous structure with definite binding sites for organometallic complexes. Prepared materials will be fully characterized and investigated in hydrogenation of CO2 to FA. One of the main targets of CO2COFs is to achieve recyclable heterogeneous catalysts with catalytic activities and efficiencies among the best reported worldwide. The results of CO2COFs project is expected attract the attention of companies related with catalysts and formic acid processing.
