This proposal aims to support an ongoing research program on materials chemistry with applications in energy conversion and storage supported by a successful Discovery Grant application. Further funding will allow the applicant to continue important work and start new fundamental research projects in the fields of electrocatalysis and high temperature and pressure (high T,p) electrochemistry.***This research program will investigate new approaches for the synthesis of advanced and well-characterized metal oxide/carbon catalyst supports. The catalytic activity and stability of supported nanoparticles (NPs) toward the reduction of oxygen and oxidation of alcohols will be studied under high T,p conditions. Particular attention will be paid to understanding, at a basic level, the conditions that result in an enhancement of the interaction between the catalyst and the support that can lead to materials with a higher stability under high T,p conditions. The reduction of oxygen on Pt and the oxidation of methanol on PtRu that were extensively studied under room temperature conditions will be used as reference systems for these initial studies.***Even though different state-of-the-art characterization techniques will be used to assess the role of the support on the activity and durability of the catalyst NPs, the most interesting data are expected to come from a high temperature and pressure dual-electrode spectroelectrochemical channel cell currently under development by the applicant's research team. The cell would allow the study of the kinetics of the reduction of oxygen and oxidation of methanol and ethanol on Pt/C and PtRu/C, as well as on other relevant electrocatalyst materials. High temperature conditions have not been explored extensively in electrochemistry, and the fact that the electrode in this cell design can also be illuminated will open new possibilities for fundamental research in the fields of photoelectrochemistry and electrochemical fuel generation using sunlight. ***The Discovery grant will provide the funding required to support the research work of five graduate students and five undergraduate summer students. HQPs working under the applicant's supervision will have access to infrastructure and research expertise that is not frequently found in other laboratories. In materials chemistry, the applicant's program has the potential to advance the field of high temperature polymer electrolyte membrane fuel cells, hydrogen production, and make significant contributions to areas and applications related to CO2 conversion to fuels, supercapacitors, and lithium batteries.**

该提案旨在支持一项正在进行的材料化学研究项目，该项目在能源转换和存储方面的应用得到了成功的发现补助金申请的支持。进一步的资助将使申请人能够继续重要的工作，并在电催化和高温高压（高 T,p）电化学领域启动新的基础研究项目。***该研究计划将研究合成先进和良好表征的金属氧化物/碳催化剂载体。将在高 T,p 条件下研究负载纳米颗粒 (NP) 对氧还原和醇氧化的催化活性和稳定性。我们将特别关注在基本层面上理解导致催化剂和载体之间相互作用增强的条件，从而导致材料在高 T,p 条件下具有更高的稳定性。在室温条件下广泛研究的 Pt 上的氧还原和 PtRu 上的甲醇氧化将用作这些初步研究的参考系统。***尽管将使用不同的最先进的表征技术为了评估载体对催化剂纳米粒子的活性和耐久性的作用，最有趣的数据预计来自申请人的研究团队目前正在开发的高温高压双电极光谱电化学通道电池​​。该电池可用于研究 Pt/C 和 PtRu/C 以及其他相关电催化剂材料上氧气还原以及甲醇和乙醇氧化的动力学。高温条件在电化学方面尚未得到广泛探索，而这种电池设计中的电极也可以被照亮，这一事实将为光电化学和利用阳光产生电化学燃料领域的基础研究开辟新的可能性。 ***发现补助金将提供支持五名研究生和五名本科生暑期学生的研究工作所需的资金。在申请人的监督下工作的总部将能够获得其他实验室不常见的基础设施和研究专业知识。在材料化学领域，申请人的项目有潜力推动高温聚合物电解质膜燃料电池、制氢领域的发展，并对二氧化碳转化为燃料、超级电容器和锂电池的相关领域和应用做出重大贡献。 **
