Exsolved catalysts for the conversion of CO2 to methanol

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，这导致了额外的排放。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。氢气的使用，加上多余的二氧化碳的转化，用于化学原料的可持续合成，包括甲醇和更高的碳氢化合物，可能导致二氧化碳排放量下降90%，使这一过程成为一个令人兴奋的未来前景。事实上，利用现有技术，利用二氧化碳作为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。为了实现这一目标，为二氧化碳加氢设计高效的催化剂至关重要。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，用于从二氧化碳中生产化学品和燃料，以及(b)发展对控制可选性和活性的原理的基本理解，以获得所需产品。为了实现这些雄心勃勃的目标，我们采用了溶出法，一种生产纳米颗粒的方法，它显示出增强的活性和稳定性，对抗失活机制。该项目将探索从一系列载体中分离出高活性异质结构，以开发最先进的催化剂，将二氧化碳转化为高价值的燃料或化学品。

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.
