PI: Hicks， jason提案号：1125145化石燃料以外的能源生产领域的技术进步是世界面临的一个关键需求。因此，这个话题引起了社会各阶层学生和科学家的极大兴趣。从生物质中提取的生物燃料是一种有吸引力的替代能源技术，但在寻求生产经济、稳定、可用的生物燃料的过程中，目前最重要的方面是开发高活性和选择性的多相催化剂。1,2本提案的实验重点是通过详细的实验方法确定木质素为基础的模型化合物的加氢脱氧（HDO）机制，该机制使用新型负载双金属FeMo磷化物催化剂用于先进的生物燃料工艺。一旦反应机制被明确确定，催化剂合成就可以被调整，以最大限度地提高活性和选择性，用于下一代生物燃料工艺。采用在线催化反应器进行气相产物升级的热解GC/MS实验，并在搅拌容器中进行间歇反应，比较气相升级和液相升级。知识价值：最终，该提案的结果将为木质素升级为潜在的工业规模操作的燃料提供证据。这项工作将扩大现有木质素HDO的认识，从研究简单的，取代的苯酚化合物到更复杂的木质素为基础的模型化合物，这方面的研究是缺乏的。此外，我们将合成并表征木质素基化合物HDO的新型双金属催化材料。这项工作将通过提供有关反应机制的关键基础信息，大大促进对这一过程的理解，这将随后导致更好的生物燃料生产催化过程。除了生物燃料的生产，这些知识可以用来增加从木质素为基础的资源合成特种化学品的基本认识。更广泛的影响：在有效利用生物质作为能源生产资源方面取得的进展将使社会更接近满足世界需求的目标。以可持续的方式满足美国的能源需求。对反应机制的基础知识的确定将有助于创造对生物质液化和脱氧具有高选择性的新催化剂，这将加快生物燃料的可用性。通过巴黎圣母院能源中心和可持续能源倡议的成员资格，该提案的结果将在广泛的受众中传播。一年一度的圣母院能源周是一个向校园内的团体、校友和当地社区展示能源问题研究解决方案的机会。针对这些广泛的受众激发了学生的探究，吸引了学生研究人员，并提高了公众对圣母院能源研究和能源问题的认识和知识。此外，从bridge提案中获得的结果将纳入当前和未来的研究生/本科课程，特别是目前正在设计的催化课程的专题。扩大参与：该提案旨在将能源、生物燃料和催化方面的研究与针对社区高中群体和圣玛丽学院女本科生的教育工作结合起来，特别是寻求对代表性不足的学生进行指导。每年都会举办“催化和生物燃料”实验室开放日，让当地高中生在实验室里度过一天，协助进行生物燃料实验，并了解能源问题和研究。此外，圣玛丽学院的女本科生将被招募到PI的实验室进行研究，作为与圣母大学提供的双学位项目的一部分。最后，多样性将在我们的研究小组中建模，并将成为PI的关键目标。在未来的几年里，美国集团将继续发展。

PI: Hicks, JasonProposal Number: 1125145Technological advancement in the area of energy production from sources other than fossil fuels is a critical need facing the world. As such, this topic is of great interest to students and scientists from all segments of society. One attractive alternative energy technology is biofuels derived from biomass, but the most important aspect currently missing in the quest to generate economical, stable, useable biofuels is the development of highly active and selective heterogeneous catalysts.1, 2 The experimental focus of this proposal is the determination of the mechanisms for hydrodeoxygenation (HDO) of lignin-based model compounds using novel supported bimetallic FeMo phosphide catalysts for use in advanced biofuels processes using a detailed experimental approach. Once the reaction mechanisms are clearly determined, catalyst synthesis can be tailored to maximize activity and selectivity for use in next-generation biofuels processes. Pyrolysis GC/MS experiments with an in-line catalytic reactor to upgrade the vapor phase product and batch reactions in a stirred vessel to compare vapor phase upgrading and liquid phase upgrading will be conducted.Intellectual Merit: Ultimately, the results of this proposal will provide evidence of lignin upgrading to fuels for potential industrial scale operation. This work will expand existing lignin HDO understanding from studies on simple, substituted phenol compounds to more complex lignin-based model compounds, for which studies are lacking. In addition, we will synthesize and characterize new bimetallic catalytic materials for HDO of lignin-based compounds. This work will significantly advance the understanding of this process by providing key fundamental information on the reaction mechanisms, which will subsequently lead to better catalytic processes for biofuels production. In addition to biofuels production, this knowledge could be used to increase fundamental understanding of specialty chemicals syntheses from lignin-based resources.Broader Impacts: Advancement toward the effective use of biomass as a resource for energy production will move society closer to the goal of meeting the world?s energy needs in a sustainable manner. The determination of the foundational knowledge of reaction mechanisms will enable the creation of new catalysts with high selectivity towards biomass liquefaction and deoxygenation, which will expedite biofuels- usability. Through membership in the Notre Dame Energy Center and Sustainable Energy Initiative, the results from this proposal will be disseminated across a wide audience. The annual Energy Week at Notre Dame is an opportunity to present research solutions to energy problems to groups across campus as well as alumni and the local community. Targeting this broad audience spurs student inquiry, attracts student researchers, and increases public awareness and knowledge of energy research at Notre Dame and energy issues in general. Also, the results obtained from this BRIGE proposal will be incorporated into current and future graduate/undergraduate courses, and specifically into a special topic in catalysis course that is currently being designed.Broadening Participation: This proposal seeks to integrate research in energy, biofuels, and catalysis with educational efforts targeted at high school groups in the community at large and female undergraduates from St. Mary's College, specifically seeking to mentor underrepresented students. A "Catalysis and Biofuels" laboratory open house day will be held every year for local high school students to spend a day in the lab assisting with biofuels experiments and learning about energy issues and research. In addition, female undergraduates from St. Mary's College will be recruited to conduct research in the PI's lab as part of the dual degree program offered with the University of Notre Dame. Lastly, diversity will be modeled in our research group and will be a key goal of the PI?s group over the coming years.
