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计划，该计划在能源转换和储存方面的应用得到了成功的发现资助申请的支持。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）电化学领域开始新的基础研究项目。该研究计划将研究合成先进和良好表征的金属氧化物/碳催化剂载体的新方法。本文将研究负载型纳米粒子在高温高压条件下对氧还原和醇类氧化的催化活性和稳定性。将特别注意在基本水平上理解导致催化剂和载体之间的相互作用增强的条件，所述相互作用可以导致在高T，p条件下具有更高稳定性的材料。在室温条件下广泛研究的氧在Pt上的还原和甲醇在PtRu上的氧化将被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来评估载体对催化剂NP的活性和耐久性的作用，最令人感兴趣的数据预计来自申请人的研究小组目前正在开发的高温和高压双电极光谱电化学通道池。该电池将允许在Pt/C和PtRu/C上以及在其他相关电催化剂材料上研究氧的还原和甲醇和乙醇的氧化的动力学。高温条件在电化学中还没有得到广泛的研究，而这种电池设计中的电极也可以被照亮的事实将为光电化学和利用太阳光的电化学燃料生成领域的基础研究开辟新的可能性。发现补助金将提供所需的资金，以支持五名研究生和五名本科生暑期的研究工作。在申请人监督下工作的HQP将有机会获得其他实验室不经常发现的基础设施和研究专门知识。在材料化学方面，申请人的计划有可能推动高温聚合物电解质膜燃料电池，制氢领域的发展，并为与CO2转化为燃料，超级电容器和锂电池相关的领域和应用做出重大贡献。
