| 中文简介: |  毫无疑问，对催化中的结构活性关系的合理解释是寻求工程化分子化学转化的关键任务。在这方面，公认的基于结构的微动力学模型的多尺度分析是实现对催化剂功能的详细机械理解的基本关键工具。然而，在现有技术的微动力学建模中，目前忽略了催化剂的结构对反应性和选择性的影响。在本次演讲中，我将介绍一种通过在理论和实验之间的双反馈回路中将不同精度级别的方法分层组合来分析非均相催化中结构活性关系的方法的开发方法。这包括开发新颖的实验工具和基本原理分析。将介绍在CH4活化为合成气的情况下的一些实例。 |
| 课程简介: | There is no doubt that the rational interpretation of the structure-activity relation in catalysis is a crucial task in the quest of engineering the chemical transformation at the molecular. In this respect, multiscale analysis based on structure-dependent microkinetic modelling is acknowledged to be the essential key-tool to achieve a detailed mechanistic understanding of the catalyst functionality. However, the effect of the structure of the catalyst on reactivity and selectivity is at present neglected in state-of-the-art microkinetic modelling. In this talk, I will present the development of a methodology for the analysis of the structure-activity relation in heterogeneous catalysis by hierarchically combining methods at different levels of accuracy in a dual feed-back loop between theory and experiments. This includes the development of both novel experimental tools and first-principles analysis. Selected examples in the context of CH4 activation to syngas will be presented. |
