Fossil-derived liquid fuels have dominated the aviation and motor transport industry due to their high energy density and ease of manipulation. However, ever-growing concerns over CO2 emissions and improving battery technology are leading to rapid changes in energy sources for motor transportation. Consequently, the UK government, like many others, has announced a ban on the sale of new petrol and diesel cars from 2035. Unfortunately, batteries cannot be deployed for commercial aviation due to the low power to weight density of current battery technology. Developing carbon neutral aviation fuel through CO2 hydrogenation, where H2 is derived from water electrolysis, is a priority for the aviation industry and UKRI (https://ktn-uk.org/transport/sustainable-aviation/). Recent reports show that intimate combinations of zeolite catalysts with zinc-based hydrogenation catalysts produces a multifunctional material that can hydrogenate CO2 to liquid range fuels (e.g. Nat. Commun., 2017, 8, 15174; ACS Cent. Sci., 2020, 6, 1657). Early work has shown that macroscopic control of the catalyst composite can tune the product range to different fuel types (gasoline vs jet fuel). However, much less is known about how the speciation and microscopic intimacy of the catalyst components affects product selectivity. Using our knowledge and control of zinc speciation in modified zeolites (Sustainable Energy Fuels, 2021, 5, 2136 and ChemPhysChem, 2020, 21, 673) we will develop structure-function activity relationships that will enable rational catalyst design to target sustainable jet fuel. The multifunctional catalysts will be made solely from earth abundant, non-toxic elements (Al, Si, Zn, Fe, Cu) and enable a circular aviation fuel economy.

化石衍生的液体燃料因其高能量密度和易于操作而主导了航空和汽车运输业。然而，对二氧化碳排放日益增长的担忧和不断改进的电池技术正在导致汽车运输能源的快速变化。因此，英国政府和其他许多国家一样，宣布从2035年起禁止销售新的汽油和柴油汽车。不幸的是，由于当前电池技术的低功率重量密度，电池不能用于商业航空。通过二氧化碳加氢（氢气来自水电解）开发碳中性航空燃料是航空工业和UKRI的优先事项（https://ktn-uk.org/transport/sustainable-aviation/）。最近的报道表明，沸石催化剂与锌基加氢催化剂的密切结合产生了一种多功能材料，可以将二氧化碳加氢成液体燃料（如Nat. common）。浙江农业学报，2017,8,15174；美国化学学会分类科学浙江农业学报，2020,6,1657)。早期的工作表明，对催化剂复合材料的宏观控制可以调整产品范围，以适应不同的燃料类型（汽油和航空燃料）。然而，关于催化剂组分的形态和微观亲密度如何影响产物选择性，人们知之甚少。利用我们的知识和对改性沸石中锌形态的控制（可持续能源燃料，2021年，5,2136年和化学物理计划，2020年，21,673年），我们将开发结构-功能-活性关系，这将使合理的催化剂设计成为可持续航空燃料的目标。多功能催化剂将完全由地球丰富的无毒元素（Al, Si, Zn, Fe, Cu）制成，并实现循环航空燃油经济性。
