Накратко на български

Медни наноструктури с различна форма се тестват за превръщане на въглеродния диоксид в полезни вещества като метан и етилен. Това помага за намаляване на парниковите газове и глобалното затопляне чрез използване на възобновяема енергия.

Surface and sub-surface modified nano-electrocatalysts for the conversion of CO2 to value-added products: A structure-selectivity-mechanism-stability catalog

Anthropocene, the age in which human intervention with nature is highest in affecting the global weather patterns as well as the pollution of entire ecosystem. The major role in increasing the global temperature is attributed to the increase in the concentration of greenhouse gases, especially fossil fuels-based CO2. Concerning this, electrochemical and photo-electrochemical based technologies offer promising solutions if provided with the renewable electrical energy sources to make the mission energy efficient. With this background, the strategic goals of the Marie Skłodowska-Curie Actions (MSCA) entitled “Surface and sub-surface modified nano-electrocatalysts for the conversion of CO2 to value-added products: A structure-selectivity-mechanism-stability catalog” is to address and tackle the contemporary challenges in the field of electrocatalytic conversion of CO2 to value-added products (VAPs). Four grand objectives: a). activity, b). selectivity, c). mechanism and d). stability of surface and sub-surface modified copper-based nanostructures. In order to comprehend the structure-activity-selectivity-stability relationships for these objectives, four shape and size selective copper nanostructures are prepared viz., copper-based nanospheres, nanocubes, nano-octahedras and nanowires. Facility for online-gas chromatography for electrochemical CO2 reduction is established and NMR protocols for liquid products are also standardized at the host institute. With the appropriate electrochemical protocol, we were able to produce selectively methane over copper nanocubes. Furthermore, with the modified nanowires we were able to produce selectively ethylene as a major product.

Цел на проекта

In the age of Anthropocene, major challenges faced by mankind today are the global climate change and the associated huge energy crisis due to ever increased population demand. So, the contemporary interests are towards energy storage and conversion reactions and in generating the alternative fuels (from CO2, waste to wealth strategy). Copper is the known best electrocatalyst for the reduction of CO2 (green-house gas). However, Cu is not particularly selective-stable electrocatalyst and is vary prone to deactivation; selectivity and stability are two important strictures directly associated with the geometric and electronic structure of the catalyst and hence on the CO2 conversion efficacy. Herein, we propose few strategies with CO2-CAT-ALOG such as doping with IIIA group elements, to effectively have active-selective-stable electrocatalyst to reduce CO2 to >C1 desired products and explain the mechanism of actions by carrying out experiments and theory in tandem. Appropriately, this proposal aims at the (i) synthesis of atomically precise, zero-dimensional (0D) modified Cu nanoparticles (mCNPs) supported over 2D materials, (ii) exploring the parameters governing the CO2 activation and stability of the reaction intermediates with the aid of DFT calculations (modelling and simulation at nano-scale) and micro-kinetic modelling (iii) detailed study on selectivity and stability of modified surface and sub-surface of CNPs with IIIA-group with the aid of high-end multi-analytical methodologies. This CO2-CAT-ALOG approach will not only bridge the gap between theory and experiments at the nano-scale level to a possible extent, but also facilitates intra-European knowledge transfer along with direct societal impacts. In addition, proposed work will not only provide solid guidelines to smart-design and screen the robust active-selective-stable electrocatalysts but also addresses issues to overcome impediments in the field of electrocatalysis of CO2 in near future.
