With the support of the Chemical Catalysis program in the Division of Chemistry, Kunlun Ding of Louisiana State University (LSU) is developing novel catalysts for converting natural gas and carbon dioxide into value-added chemicals. This project will explore new chemistry for the preparation of well-defined catalysts with uniform compositions. Dr. Ding’s group will combine spectroscopy and electron microscopy techniques to understand the structural evolution of the catalysts as they are used. Dr. Ding will introduce research frontiers and integrate experiments into the LSU curriculum and arrange site undergraduate and graduate student visits to local chemical industry and a synchrotron facility. Demonstration modules related to this project will be developed for outreach programs at LSU to attract underrepresented K-12 students to science.Dr. Ding and his research group are developing site-specific synthesis methods and characterization techniques for tackling the structural heterogeneity issues in heterogeneous catalysis. The proposed project will explore surface inorganometallic chemistry for controlling the interactions between different metal complexes in the synthesis of supported bimetallic and intermetallic catalysts. These catalysts will be used in the tandem catalytic conversion of light alkanes and carbon dioxide, producing olefins, hydrogen, and carbon monoxide. The gained knowledge on the structural dynamics of well-defined supported bimetallic and intermetallic catalysts under reaction conditions is expected to provide a basis for more accurate computational modeling to understand the structure-property relationship of bimetallic and intermetallic catalysts, and further guide the rational catalyst design for alkane and carbon dioxide activation. The new approach for the synthesis of well-defined supported bimetallic and intermetallic catalysts has the potential for longer term scientific impact in other thermocatalytic and electrocatalytic applications.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.

在化学催化计划的支持下，路易斯安那州立大学（LSU）的Kunlun Ding正在开发用于将天然气和二氧化碳转化为增值化学品的新型催化剂。该项目将探索新的化学方法，以制备具有均匀成分的明确定义的催化剂。 Ding博士的组将结合光谱和电子显微镜技术，以了解使用催化剂的结构演化。 Ding博士将在LSU课程和安排现场的本科生和研究生访问当地化学工业和同步器设施中介绍研究前沿和集成实验。与该项目相关的示范模块将在LSU的外展计划开发，以吸引代表性不足的K-12学生进入Science.dr。 Ding及其研究小组正在开发特定地点的合成方法和特征化技术，以解决异质催化中的结构异质性问题。拟议的项目将探索表面无良金属化学，以控制不同金属络合物在合成的双金属和金属间催化剂中的相互作用。这些催化剂将用于轻烷烃和二氧化碳的串联催化转化，产生烯烃，氢和一氧化碳。关于反应条件下有明确的支撑双金属和金属间催化剂的结构动力学的知识，预计将为更准确的计算建模提供基础，以了解双金属和金属间催化剂的结构 - 质体关系，并进一步指导烯烃和碳二氧化物氧化抗氧化物的理性催化剂设计。合成精心定义的双金属和金属间催化剂的新方法具有在其他热催化和电催化应用中产生长期科学影响的潜力。该奖项反映了NSF的法定任务，并通过评估该基金会的智力优点和广泛的影响来评估NSF的法定任务。
