Metal Organic Frameworks (MOFs) Supported Single Atom Catalysts (SACs) for Solar Fuel Conversion

Humphrey Teurai Chiromo

Abstract

The continual reliance on non-renewable energy sources from fossil fuels tomeet the world's energy demand is causing serious environmental problems such asair pollution and global wamming, hence there is a need of an alternative cleansustainable energy source. Exploration of clean sustainable renewable energiesshows great promise to replace fossil fuels to meet global energy needs. Among therenewable energy sources, solar energy represents one of the most promisingalternative energy sources due to its abundance and sustainability. However, themajor challenge is the harvesting and storage of solar energy. One of the promisingapproaches to resolve these challenges is through artificial photosynthesis whichenables harnessing of solar energy and store the energy in fomm of chemical bonds.My research projects focused on the development of photocatalyticmaterials, i.e., metal-organic fiameworks (MOFs) supported single atom catalysts(SACs), which can be utilized as light harvesting and charge separation materials todrive the hydrogen evolution reaction (HER) to produce solar fuels. In addition. 1explored the application of metal-organic frameworks (MOFs) supported singleatom catalysts (SACs) in light induced organic transformation Sonogashira C-Ccoupling reaction, By using a combination of spectroscopic techniques such as X-ray absorption spectroscopy(XAS), X-ray transient absorption spectroscopy (XTA),and steady state fluorescence, we studied the influence of single atom catalysts onthe charge separation effciency, catalytic activity, and selectivity of the MOFssupported SACs materials for photocatalytic reactions.The research projects highlighted the importance of tuning the opticalproperties and charge separation efficiency in photocatalysis, thus providingimportant insights for rational design of better photocatalytic materials for solar fielconversion and light induced organic transformation reactions
