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.

开发用于生物质转化的工业相关催化剂的关键挑战是将大生物分子的高表面积和活性与主要位于材料的内部孔内的活性位点的低传质阻力相结合。该项目旨在开发独特的新型多尺度多孔材料，而不是采用具有单峰孔径的常规微孔沸石和中孔二氧化硅，该材料将联合收割机的活性位点可达性和有效的质量传输效应与高表面积和活性位点的空间限制的优点相结合。自组装的基础科学将被用于将单个金属离子和/或二维组装体封装在均匀的二氧化硅基质中，以开发具有独特反应性的新型催化剂。将为批量生产开发处方方案，然后进行规模放大。
