Накратко на български
Електрохимичното превръщане на въглеродния диоксид в течни горива изследва как структурата на повърхностите, където протичат реакциите, влияе върху ефективността им. Това е важно, за да се подобри превръщането на възобновяемата електроенергия в химически горива и да се намали зависимостта от изкопаемите горива.

Sustainable liquid fuels from CO2 electroreduction
This project addresses the low conversion energy efficiency between chemicals and electricity, which economically limits the wide-spread adoption of renewable energy technologies. Renewable electricity becomes more and more cheap and accessible, and could be used to electrify industry and automobile to mitigate our dependence on fossil fuels. However, the current technology for electricity-chemicals conversion remains too low to be competitive with conventional ones. The key technological limitation lies on electrocatalysis, which is closely related to an electrified interface. It is therefore important to enhance electricity-chemical conversion (achieved via electrochemical reactions occurring at electrified interface), which requires fundamental understanding of how the structure of electrified interface impacts the electrocatalysis (i.e. conversion efficiency), and further transferring such understanding to practical applications by advancing materials and building devices. The overall objectives are providing broad guideline for future design of electrified interface for target electrochemical reactions, and practical demonstration of electricity-chemical conversion.

Цел на проекта
Fossil fuels have been crucial for the prosperity of human society since the industrial revolution, but have also brought about many critical issues, such as global warming. To meet the ambitious goals set out in the Paris Agreement, it is imperative to explore sustainable fuel sources. Liquid fuels produced from renewable-electricity-driven CO2 reduction reaction (CO2RR) are promising candidates because they simultaneously allow for a carbon-neutral energy cycle and the storage of renewable yet intermittent energy. Due to its high energy density and suitable octane number, propanol is one of the most desired products from CO2RR as direct fuels and fuel additives. However, current state-of-the-art catalysts do not exhibit more than 15% selectivity for propanol, which is a huge impediment towards the practical adoption of CO2-to-propanol electrolysis. Raising the selectivity requires intricate knowledge of what catalyst descriptors drive propanol formation, in order to predict and discover ideal catalyst/system combinations, which are the objectives of this proposal. To achieve these goals, the optimum electrode-electrolyte interface will be identified based on well-defined single-crystal-electrode experiments; reaction intermediates and pathways will be identified and studied by in situ spectroscopy methods and DFT calculations; theory-guided-designed nanocatalysts will be synthesized and subsequently integrated into an optimized CO2RR electrolyser to produce propanol at industrially relevant current densities. Through successful completion of the proposed research, an efficient CO2-to-propanol electrolysis system will be developed together with an in-depth understanding of CO2RR mechanism.
