The broader impact/commercial potential of this Small Business Technology Transfer (STTR) Phase II project is to help lessen the environmental burden of climate change by reducing greenhouse gas emissions and dependence on fossil fuels. Climate change is an urgent environmental challenge and to address it, it is essential to provide alternatives to the use of fossil fuels that generate greenhouse gases. Nearly all the jet fuel or aviation fuel in use today is made from crude oil, which is a fossil fuel. This project provides an alternative technology that makes sustainable aviation fuel (SAF) using only carbon dioxide (CO2) captured from waste sources, relatively small volumes of water, and renewable (e.g., solar and wind) electricity. Catalysts are one of the key components of the process that is used to produce this SAF, helping the chemical reactions that produce the fuel occur more efficiently. This project will optimize the catalysts for improved production of SAF. This STTR Phase II project seeks to significantly improve SAF production by developing and characterizing catalysts that convert carbon dioxide (CO2) into the hydrocarbon constituents in sustainable aviation fuels using advanced characterization techniques such as x-ray diffraction, x-ray photoelectron spectroscopy, and electron microscopy. The process will use catalysts as mimics for photosynthesis, taking air (as a CO2 source), water (as a hydrogen source) and sunlight (as an energy source) and converting them into sustainable chemicals and transportation fuels. The only by-products are oxygen and water. Many other related processes often rely on multiple reaction steps to target the same products. This project develops a novel family of proprietary catalysts to convert CO2 to fuels and chemicals in a single step via a direct CO2 hydrogenation process, enabling yields even greater than the theoretical maximum of legacy processes, such as Fischer-Tropsch. This new process eliminates the need for extra intermediate steps that negatively affect process energy demands, emissions, capital and operational cost, and product selling price. The successful outcome of the project will allow significant improvements in production and economics of sustainable aviation fuels.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

这种小型企业技术转移（STTR）II期项目的更广泛的影响/商业潜力是通过减少温室气体排放和对化石燃料的依赖来帮助减轻气候变化的环境负担。气候变化是一项紧迫的环境挑战，要解决它，至关重要的是，对于使用产生温室气体的化石燃料的使用是必不可少的。如今，几乎所有正在使用的喷气燃料或航空燃料都是由原油制成的，这是化石燃料。该项目提供了一种替代技术，仅使用从废物来源捕获的二氧化碳（CO2），相对较少的水和可再生（例如太阳能和风能）的电力来制造可持续的航空燃料（SAF）。催化剂是用于生产此SAF的过程的关键组成部分之一，帮助产生燃料的化学反应更有效地发生。该项目将优化催化剂，以改善SAF的生产。 该STTR II期项目旨在通过使用X射线衍射，X射线衍射型，X射线光电学光谱和电子显微镜，使用先进的表征技术（例如，将二氧化碳（CO2））转化为可持续航空燃料中的碳氢化合物成分，从而显着改善SAF的生产。该过程将使用催化剂作为光合作用的模拟物，将空气（作为二氧化碳来源），水（作为氢来源）和阳光（作为能源）（作为能源），并将其转换为可持续的化学品和运输燃料。 唯一的副产品是氧气和水。许多其他相关的过程通常依靠多个反应步骤来针对相同的产品。该项目开发了一个新型的专有催化剂家族，通过直接的CO2氢化过程将CO2转换为燃料和化学物质，使得能够产生的产生甚至大于遗产过程的理论最大值，例如Fischer-Tropsch。这个新的过程消除了对额外的中间步骤的需求，这些步骤会对流程的需求，排放，资本和运营成本以及产品销售价格产生负面影响。该项目的成功结果将允许可持续航空燃料的生产和经济学的重大改善。该奖项反映了NSF的法定任务，并被认为是值得通过基金会的知识分子优点和更广泛的影响评估标准通过评估来支持的。
