Накратко на български

Хибриден фотокатализатор от зеолит, метални наночастици и светлоулавяща система превръща въглеродния диоксид в метан чрез слънчева светлина. Това помага за намаляване на атмосферните емисии и предлага алтернатива на изчерпващите се изкопаеми горива.

ZEolitic reactor hosting Subphthalocyanines and Metal Oxides as photocatalytic system for opto-electronic applications

Planet population and with it the energetic demand is increasing, therefore there is the necessity of finding alternative fuel as fossil fuels are finishing. Solar light photocatalytic CO2 reduction to valuable chemicals and fuels is increasingly attracting the attention of the scientific community as one of the “greenest” alternatives to fossil fuels and it could also serve to decrease the levels of atmospheric CO2 emissions, mitigating the greenhouse effect problem. Efficiency values reported so far in the literature are far from optimal. Some of the problems to overcome are the limited wavelength response (frequently limited to only 4% of the total solar light energy), photocorrosion and low quantum efficiencies due to inefficient charge separation. Most of the reported photocatalysts incorporate precious metals and rare elements, which increase the cost and their low abundance would raise the issue of exhausting its reserves in the future. This proposal aims to address these issues by developing an efficient hybrid photocatalytic system made out of non-critical starting materials and chemicals, able to photocatalyse the CO2 reduction to obtain methane (usable as energy source) using as solely source solar light. This project allowed to obtain a hybrid photocatalyst constructed from three different materials, a light -harvesting system, metal nanoparticles and zeolite as support, that can be subsequently used to obtain energy. The proposed hybrid photocatalyst have successfully been prepared and fully characterised. In the photoassisted CO2 conversion reaction this photocatalyst proved to be efficient for methane evolution, hence achieving the main goal of this project, green energy production.

Цел на проекта

Solar light promoted CO2 reduction could be the “greenest” alternative to fossil fuels as it would also decrease the atmospheric CO2 emissions. ZESMO comes from the idea of developing an efficient, robust and low-cost photocatalytic system to improve reported conversion rates for CO2 reduction by H2O. Some of the problems to overcome are the limited wavelength response (frequently limited to only 4% of the total solar light energy), photo-corrosion and low quantum efficiencies. The photocatalyst presented in this proposal is designed to tackle these issues and achieve a better performance by incorporating Suphthalocyanine (SubPc) (light harvester) and metal clusters (semiconductor) into zeolites. Zeolite’s pores act as “nano-reactors” entrapping both species and enhancing chemical stability and catalytic activity. The second part of the project deals with the evaluation of the photocatalytic activity of a series of synthesised hybrids. The system will be subjected to operation lifetime studies for its possible future commercialisation. The development and management of ZESMO would introduce me to important fields such as inorganic chemistry, photochemistry and material science. It would provide the best opportunity for me to grow as an independent researcher. I would contribute with my expertise in organic and supramolecular chemistry, especially in synthesis and characterisation of SubPc and nanoparticles.SubPc-zeolite hybrids are unknown, to date there are no examples of zeolites entrapping two different systems in the same pore. Therefore the expected scientific impact is very high. The overall purpose of the proposal is to find an efficient photocatalyst which will be tested for the implementation and real use for society. Since this achievement would give access to solar fuels, it would impact not only EU but worldwide economy. ZESMO would also be an environmental breakthrough towards mitigation of the greenhouse effect problem.
