The UK Government pledged to net-zero greenhouse gas emissions by 2050, significantly cutting back on emissions by 2035. However, currently, 90% of our energy supply is dependent on fossil fuels resulting in additional emissions. To decarbonise our energy supply and reach net zero, we need to increase our use of hydrogen as well as utilise the CO2 being emitted. The use of hydrogen, coupled with the conversion of that excess CO2, for the sustainable synthesis of chemical feedstocks, including methanol, and higher hydrocarbons, could result in 90% drop in CO2 emissions making thisprocess an exciting future prospect. Indeed, the use of CO2 as feedstock for fuel and chemicals synthesis is possible using existing technology but materials challenges, such as kinetic limitations and poor stability, prevent the development of efficient processes. For this to become viable, efficient catalyst design tailored towards CO2 hydrogenation is of essence. In this project we are aiming (a) to design and prepare stable and highly active materials for the production of chemicals and fuels from CO2, and (b) developing fundamental understanding of the principles that govern electivity and activity to the desired products. To accomplish these ambitious targets, we employ exsolution, an approach to producing nanoparticles which display enhanced activity and stability against deactivation mechanisms. This project will explore the exsolution of highly active heterostructures from a range of supports seeking to develop the new state of the art catalysts for CO2 conversion to high value fuels or chemicals.

英国政府承诺到 2050 年实现温室气体净零排放，到 2035 年大幅削减排放量。然而，目前英国 90% 的能源供应依赖化石燃料，导致排放量增加。为了使我们的能源供应脱碳并达到净零排放，我们需要增加氢的使用并利用排放的二氧化碳。使用氢气，加上过量二氧化碳的转化，用于可持续合成化学原料（包括甲醇和高级碳氢化合物），可以使二氧化碳排放量下降 90%，使该工艺成为令人兴奋的未来前景。事实上，使用现有技术可以使用二氧化碳作为燃料和化学品合成的原料，但动力学限制和稳定性差等材料挑战阻碍了高效工艺的开发。为了使其变得可行，针对二氧化碳加氢量身定制的高效催化剂设计至关重要。在这个项目中，我们的目标是（a）设计和制备稳定且高活性的材料，用于从二氧化碳生产化学品和燃料，以及（b）发展对控制所需产品的选择性和活性的原理的基本理解。为了实现这些雄心勃勃的目标，我们采用了外溶，这是一种生产纳米颗粒的方法，该纳米颗粒表现出增强的活性和针对失活机制的稳定性。该项目将探索高活性异质结构从一系列载体中的脱溶，寻求开发新的最先进的催化剂，用于将二氧化碳转化为高价值燃料或化学品。
