Eco-Friendly MXene-Supported Precious Metal Catalysts

The growing global challenge of climate change is primarily driven by rising CO2 emissions, and solving this problem requires new and innovative solutions. One promising approach utilizes converting CO2 into valuable chemicals and fuels, but achieving this requires the development of highly effective catalysts which are synthesized in an environmentally responsible and sustainable manner. The project explores MXenes (a class of 2D materials) as a platform for designing novel catalysts, paving the way for more sustainable CO2 conversion technologies. The synthesis of MXenes will be optimized, aiming at the simultaneous formation of rutile/anatase junctions, that is structures that have the potential to enhance catalytic performance. The next step involves depositing rhenium or ruthenium nanoparticles on the MXene support and testing them for their ability to catalyze CO2 hydrogenation. Through further modifying the surface with different molecules and reducing agents, the catalytic performance for thermal and electrochemical CO2 conversion will be optimized, ensuring long-term efficiency in technological applications. At the same time, the environmental footprint of catalyst production will be reduced by using fewer hazardous chemicals and minimizing wastewater generation. The interactions of the catalysts with CO2 will be studied by employing cutting-edge experimental techniques that provide real-time insights into chemical reactions. This deeper understanding will guide the design of catalysts that are not only more efficient but also more stable and environmentally friendly. The project combines innovative material design and sustainable methods with advanced analytical techniques, contributing to next-generation energy management and environmental solutions, offering a step forward in the global effort to reduce CO2 emissions.
