RUI: Noble Metal Phosphide Catalysts for Deep Hydrodesulfurization

无机、生物无机和有机金属化学项目的这一奖项支持了西华盛顿大学（WWU）的Mark E. Bussell教授和韦恩州立大学（WSU）的Stephanie L. Brock教授开发基于贵金属磷化物的高活性和耐硫加氢处理催化剂的工作。为烷基取代二苯并噻吩的深度加氢脱硫（HDS）量身定制贵金属磷化物催化剂的性能；从原油中去除这些物种对超低硫燃料的生产至关重要。采用程序升温还原（TPR）法制备了分散在高比表面积二氧化硅上的贵金属单金属和双金属磷化物催化剂。这些催化剂将使用各种体积和表面敏感的物理化学技术进行表征，这些表征研究的主要目标是促进这些材料的体积和表面化学性质与其深HDS催化性能的相关性。为了更深入地了解通过TPR制备的贵金属磷化物催化剂的催化性能，将对氧化物负载的单分散金属磷化物纳米颗粒进行平行研究。拟议的研究将建立和加强两位研究者、他们的学生和太平洋西北国家实验室的科学家之间的合作活动。本科（和硕士）级别的学生将参与WSU研究项目的各个方面，WSU的博士生也将参与。

This award of the Inorganic, Bioinorganic, and Organometallic Chemistry Program supports the work of Professor Mark E. Bussell of Western Washington University (WWU) and Professor Stephanie L. Brock of Wayne State University (WSU) to develop highly active and sulfur resistant hydrotreating catalysts based on noble metal phosphides. The properties of the noble metal phosphide catalysts will be tailored for deep hydrodesulfurization (HDS) of alkyl-substituted dibenzothiophenes; the removal of these species from crude oil is crucial to the production of ultra-low sulfur fuels. Monometallic and bimetallic phosphide catalysts of noble metals dispersed on high surface area silica will be prepared using the temperature-programmed reduction (TPR) method. The catalysts will be characterized with a variety of bulk and surface sensitive physicochemical techniques, with the primary goal of these characterization studies being to facilitate correlation of the bulk and surface chemical properties of these materials with their deep HDS catalytic properties. To facilitate deeper understanding of the catalytic properties of the noble metal phosphide catalysts prepared via TPR, parallel studies will be carried out on oxide-supported, monodisperse nanoparticles of the same metal phosphides. The proposed research will build and strengthen collaborative activities between the two investigators, their students, and scientists at the Pacific Northwest National Laboratory. Undergraduate (and M.S. level) students will be involved in all aspects of the research project at WWU, as will be a doctoral student at WSU.
