项目摘要

PI: Kuhn, JohnProposal Number: 1335817Institution: University of South FloridaTitle: A Plasmon-enhanced Temperature-swing Process for Conversion of Carbon Dioxide to Carbon MonoxideThis project examines a novel photochemical route for the transformation of carbon dioxide to carbon monoxide and oxygen. The primary research goals are (1) to discover perovskite-type oxides with a large change in oxygen content (delta) for small changes in temperature in a low temperature range (T=350 to 400 deg. C), (2) to design and demonstrate monometallic silver and bimetallic silver-based particles that have peak plasmonic absorption wavelengths across the visible light spectrum resulting in a maximum temperature increase, (3) to identify the catalytic consequences of the composite materials (Ag-based phase supported on the perovskite-type oxides) on the molecular processes associated with carbon dioxide conversion and oxygen generation, and (4) to validate the predicted behaviors of prepared materials in photo-induced temperature swing separation and conversion of carbon dioxide to carbon monoxide. This project will advance the field of carbon management as well as topics of optical properties of metal nanoparticles, design of mixed metal oxides, and synergy between these two sets of materials. The project will merge the experimental and computational aspects in both the research and in the student training. Carbon dioxide emissions are an imminent and global problem and the proposed effort could significantly impact the status quo. The project will also contribute to the focus on sustainability and energy research and teaching at USF through a multi-pronged endeavor of activities with an emphasis on building students with both experimental and computational experiences and skills.

PI：Kuhn，JohnProposal编号：1335817机构：南佛罗里达大学标题：等离子体增强的变温过程将二氧化碳转化为一氧化碳这个项目研究了一种将二氧化碳转化为一氧化碳和氧气的新的光化学途径。主要的研究目标是：(1)在低温范围内(T=350-400℃)发现氧含量变化较大的钙钛矿型氧化物。C)，(2)设计和展示在可见光光谱中具有最大等离子体吸收波长的单金属银和双金属银基粒子，从而导致最大温升；(3)确定复合材料(钙钛矿型氧化物负载的银基相)对二氧化碳转化和氧气产生的分子过程的催化作用，以及(4)验证所制备材料在光致变温分离和二氧化碳转化为一氧化碳中的预测行为。该项目将推动碳管理领域的发展，以及金属纳米颗粒的光学性质、混合金属氧化物的设计以及这两种材料之间的协同作用等主题。该项目将在研究和学生培训中融合实验和计算方面的内容。二氧化碳排放是一个迫在眉睫的全球性问题，拟议中的努力可能会对现状产生重大影响。该项目还将通过多管齐下的活动努力，促进美国联邦大学对可持续发展和能源研究和教学的关注，重点是培养具有实验和计算经验和技能的学生。
