Накратко на български

Хибридни фотокатализатори, съставени от молекулни катализатори и полупроводници, се разработват за превръщане на въглеродния диоксид и водата в горива чрез слънчева светлина. Това помага за справяне с енергийните проблеми и намаляването на парниковите газове в атмосферата.

Sunlight driven carbon-dioxide reduction: Hybrid catalytic systems consisting of molecular catalysts and light-harvesting Quantum-dots and semiconductors

Artificial photosynthesis, in which sunlight is directly used to generate fuels and value-added chemicals from carbon dioxide and water, is an attractive solution to both global energy challenges and environmental issues caused by rising levels of greenhouse gases. However, recycling the carbon dioxide in such a manner requires efficient catalysts and light-harvesters to power this energetically uphill reaction. In this context, CO2RED project is aimed towards developing new hybrid photocatalysts and photocathodes for light-induced carbon dioxide reduction using molecular catalysts and semiconductor light-harvesters. Molecular catalysts are typically transition metal complexes that display good selectivity towards CO2 reduction and offer synthetic tunability. However, their application in practical devices require mounting those molecules on a solid support to enable heterogeneous catalysis. This project focuses on integrating molecular catalysts into semiconductor materials and explores different immobilization techniques for specific surfaces. The molecule/semiconductor assembly, termed as hybrid material, is used as photocatalysts in colloidal/suspension type photoreactors for CO2 reduction. The second part of the project aims to incorporate this hybrid assemblies in transparent electrodes to build photoelectrochemical devices. Such device uses both sunlight and electricity to drive the catalytic reactions at the photoelectrodes and it offers scope for scaling up. Overall, the project aims to deliver new molecular catalysts, methods for immobilizing catalyst on surfaces, and hybrid materials capable of mediating carbon dioxide reduction driven by solar energy and electricity.

Цел на проекта

Artificial photosynthesis, in which sunlight is directly used to generate fuels from CO2 and water, is an attractive solution to both global energy challenges and environmental issues caused by rising CO2 levels. However, implementation of such a quasi-carbon-free fuel-economy requires efficient catalysts and light-harvester to power this uphill reaction. The proposed project is aimed at developing novel hybrid photocatalysts and photocathodes for light-induced CO2 reduction using molecular catalysts and semiconductor light-harvesters. Molecular catalysts will be immobilized onto the semiconductor-materials to generate robust photocatalysts, and subsequently, these semiconductor-catalyst assemblies will be transferred to transparent electrodes to build photoelectrodes. The innovative aspect of CO2RED is to employ inexpensive, carbon-based semi-conducting ligh-harvesters (carbon-nitride, carbon quantum dots) and 3d-metal based molecular catalysts, and use robust linkages to interface them with transparent photoelectrodes. Finally, this hybrid photocathode will be tested in a tandem CO2/H2O photoelectrochemical cell by coupling it with a photoanode for water oxidation. The project being at the interface of synthetic, materials, photo- and electro-chemistry, will provide an excellent opportunity for the experienced researcher (ER) to develop a wide range of technical skills. In addition, the fellowship will allow the ER to gain important complementary skills including proposal writing, manuscript preparation, public outreach, networking, and IPR protection that will be invaluable for his independent career. The combination of the cutting-edge science and training excellence of the project will greatly improve the ER’s career prospect and enhance the host group’s international reputation.
