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年大幅减少排放。然而，目前，我们90%的能源供应依赖于化石燃料，导致额外的排放。为了减少我们的能源供应并达到净零，我们需要增加氢的使用，并利用排放的二氧化碳。氢的使用，再加上多余的CO2的转化，用于化学原料的可持续合成，包括甲醇和高级烃，可以导致CO2排放量下降90%，使该过程成为一个令人兴奋的未来前景。事实上，使用现有技术将二氧化碳用作燃料和化学品合成的原料是可能的，但材料方面的挑战，如动力学限制和稳定性差，阻碍了高效工艺的发展。为了使其变得可行，针对CO2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）设计和制备稳定和高活性的材料，用于从CO2生产化学品和燃料，（B）发展对所需产品的选择性和活性的基本理解。为了实现这些雄心勃勃的目标，我们采用出溶，一种生产纳米颗粒的方法，该方法显示出增强的活性和稳定性，以对抗失活机制。该项目将探索高活性异质结构从一系列载体中的出溶，寻求开发用于将CO2转化为高价值燃料或化学品的新型最先进催化剂。
