项目摘要

As electricity derived from renewable sources becomes cheaper, its use for driving commercially relevant chemical processes has become increasingly viable, leading the path towards a sustainable energy economy. The combined research team at Purdue and University of Wisconsin Lacrosse are designing new catalysts for the conversion of carbon dioxide (CO2) to value-added products such as ethylene at industrially relevant conversion rates. The team will use their specific expertise to engineer novel layered catalyst structures, allowing the resulting materials to be more robust, efficient, and faster for CO2 conversion. This collaborative project involving both undergraduate and graduate researchers will also impact a broad range of technologies related to renewable energy, transportation, and defense. The project will promote knowledge-sharing activities such as regular joint meetings, undergraduate research mentored closely by graduate students, and inclusion of research activities into the curriculum. The project will also involve participation of underrepresented groups in working with research-intensive universities with a focus on skill-building activities such as group presentations, and scientific writing.This project aims to develop porous bi-layer catalysts on gas-diffusion layer (GDL) substrates which can then be used inside gas-fed carbon dioxide (CO2) electrolyzers allowing conversion to valuable C2+ products such as ethylene, at industrially relevant rates. The guiding principle of the project rests on using the bi-layer structure to break CO2 reduction scaling relations by creating asymmetric reaction sites, allowing greater selectivity through a cascade approach than from a single material. The use of a GDL substrate enables the possibility of high-rate conversions not possible with traditional reactors. The project will identify the underlying factors that determine structure-property relationships of the composite bilayer-GDL heterostructure with a focus on controlling the pore size, grain size, and associated grain boundary density. Specific metal/metal oxide heterostructures will be chosen based on recently available theoretical predictions in order to reduce the reaction overpotential, which often limits the energetic efficiency. In parallel, a carefully controlled pore size will be used to promote C-C coupling reactions through nano-confinement effects. This bilayer-GDL composite structure represents a unique combination of design elements, arising from two unique skill sets in catalyst fabrication and electrochemical testing. Coupled with a novel flow-reactor, the methodology promises to provide valuable insight into the challenging problem of high rate CO2 conversion to C2+ products such as ethylene.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.
随着来自可再生能源的电力变得更便宜,将其用于驱动商业相关的化学过程变得越来越可行,从而引领通往可持续能源经济的道路。普渡大学和威斯康星州大学长曲棍球的联合研究小组正在设计新的催化剂,用于将二氧化碳(CO2)以工业相关的转化率转化为乙烯等增值产品。该团队将利用他们的专业知识设计新型层状催化剂结构,使所得材料更坚固,更高效,更快地进行二氧化碳转化。这个涉及本科生和研究生研究人员的合作项目也将影响与可再生能源,交通和国防相关的广泛技术。该项目将促进知识共享活动,如定期举行联席会议,由研究生密切指导本科生的研究,以及将研究活动纳入课程。该项目还将涉及代表性不足的群体参与与研究密集型大学的合作,重点是技能培养活动,如小组演讲和科学写作。该项目旨在开发气体扩散层(GDL)基底上的多孔双层催化剂,然后可用于气体进料的二氧化碳(CO2)电解槽中,从而转化为有价值的C2+产品,如乙烯,以工业相关的速度。该项目的指导原则在于使用双层结构,通过创建不对称反应位点来打破CO2减排比例关系,通过级联方法实现比单一材料更高的选择性。GDL底物的使用使得传统反应器不可能实现的高速率转化成为可能。该项目将确定决定复合双层-GDL异质结构的结构-性能关系的基本因素,重点是控制孔径,晶粒尺寸和相关的晶界密度。具体的金属/金属氧化物异质结构将选择基于最近可用的理论预测,以减少反应过电位,这往往限制了能量效率。同时,将使用仔细控制的孔径来通过纳米限制效应促进C-C偶联反应。这种双层GDL复合结构代表了设计元素的独特组合,来自催化剂制造和电化学测试中的两种独特技能。再加上一个新的流动反应器,该方法有望提供有价值的洞察到高速率CO2转化为C2+产品,如乙烯的挑战性问题。该奖项反映了NSF的法定使命,并已被认为是值得通过使用基金会的智力价值和更广泛的影响审查标准进行评估的支持。
