      Heterogeneous Catalysis in Nanopores: Enhancing the Accessibility of Active Sites by Hierarchical Pore Systems

       

      Nanoporous catalysts are applied in a broad range of chemical conversions. Often, however, low catalyst effectiveness factors may result, if mass-transfer limitations exist, e.g., due to large substrate molecules. Additional pore systems with larger dimensions in the macro- and mesoporous range may, thus, help to increase accessibility and mass-transfer to and away from the catalytically active sites within nanoporous catalysts. This presentation will highlight two examples of nanoporous catalytic systems demonstrating the beneficial effect of an additional system with larger pores. In particular, the enhancement of accessibility of active sits with respect to diffusion improvements by a hierarchical pores system will be discussed

      The first example treats titanium silicalite-1 (TS-1) for the epoxidation of the unsaturated fatty acid methyl esters (FAMEs) of biodiesel with hydrogen peroxide. To enhance the accessibility of the catalytically active Ti sites for FAME epoxidation in TS-1-based catalysts, nanocrystals of TS-1 are applied into which an additional mesopore system is introduced to alleviate transport hindrances. Also, nanosheets and pillared TS-1 catalysts provide highly accessible Ti sites. The
      combination of TS-1 crystals and activated carbon beads in composite catalysts represents another way to design active epoxidation catalysts using both high accessibility and the sorptive functionality for reactant enrichment in the vicinity of the active Ti sites.

      In a second example, it is shown that two enzymes, i.e., glucose oxidase and horseradish peroxidase, can be co-immobilized on a monolithic silica materials exhibiting a hierarchical system of mesopores with two different widths. The smaller pores (ca. 3-5 nm) can accommodate the enzyme with the smaller diameter, while the enzyme with the larger diameter only fit into the larger mesopores (ca. 30-50 nm). The hierarchy and interconnectivity of the pores as well as the location of the enzymes within the pore systems are confirmed by PFG NMR diffusometry. Moreover, the enzymes remain active when immobilized on the hierarchical silica support.

      ISOTOPCAT 2019

      Poitiers, FRANCE

      Espace Pierre Mendès France, 1 Place de la Cathédrale, 86 POITIERS.

      International Symposium on Isotopic Sudies in Catalysis and Electrocatalysis

      The main purpose of the ISOTOPCAT symposium is to gather the catalysis and electrocatalysis communities in order to explore, review and compare the different methods of investigation based on isotopic labeling.

      In particular the aim is to favor the exchanges between the scientists working on heterogeneous catalysis science, fuel cells and membrane technologies having important common problems to solve, especially the elucidation of diffusion and reaction mechanisms.

      To facilitate the interaction and the debates between the scientists, this three-day symposium will be limited to a maximum of 150 participants in only one session.

      Three main topics will be developed:

      •  Isotopic exchange with solids
      •  Isotopic labelling for determination of ionic transport parameters
      •  Isotopic labelling for mechanistic studies

      Keynote speakers:

      • Prof. Dr. Roger A. DE SOUZA
      • Prof Christopher HARDACRE
      • Prof. Michel CHE

      Summer School - Catalysis: from understanding to applications

      Albi

      Ecole des Mines d'Albi-Carmaux Campus Jarland 81013 Albi FRANCE

      The objective of this Summer School is to present catalysis as a tool of preference for the development of sustainable processes, respectful to the environment. Catalysis is indeed at the heart of Green Chemistry: atom economy, selectivity and energy economy, transformation of raw materials into targeted products.

      This Summer School focuses on understanding how the catalytic processes take place, including cutting-edge techniques, modelling and design of reactors. The activation of small molecules will be presented as an application show-case.

      Participants are encouraged to submit posters, which will also be presented by flash communications.

      Deadline for registration and poster abstract submission:  April 30, 2019
