3D Assembly of Single Atoms into multi-structured catalysts

开发与工业相关的生物质转化催化剂的一个关键挑战是将高表面积和活性与大型生物分子对活性位点（主要位于材料内部孔隙内）的低传质阻力结合起来。该项目旨在开发独特的新型多尺度多孔材料，以取代传统的单峰孔径的微孔分子筛和介孔二氧化硅，该材料将结合活性位点可达性和高效质量传递效应的优势，以及活性位点的高表面积和空间限制。自组装的基础科学将被用于将单个金属离子和/或二维组件封装在均匀的二氧化硅基体中，以开发具有独特反应活性的新型催化剂。将为批量生产制定配方协议，然后扩大规模。

A critical challenge in developing industrially relevant catalysts for biomass conversion is to combine high surface areas and activity with low mass transfer resistance of large biomolecules to the active sites, predominantly located inside the internal pores of the materials. Instead of employing conventional microporous zeolites and mesoporous silicas with unimodal pore sizes, the project aims to develop unique novel multiscale porous materials which will combine the advantages of active site accessibility and efficient mass transport effects with high surface area and spatial confinement of active sites. Fundamental science of self-assembly will be employed to encapsulate single metal ions and/or 2D assemblies within the uniform silica matrix to develop novel catalyst with unique reactivity. Formulation protocols will be developed for the batch manufacturing followed by the scale up.
