WebTakashi Kyotani, in Carbon Alloys, 2003. 2.1 Control of Micropores. Porous carbons are characterized by their highly developed micro- and meso-pore structures, micropores being essential for adsorption of small molecules. Efforts to control structure in carbons are particularly relevant to the molecular sieving carbons (MSC). The porosity of MSC … Web1 de jun. de 2024 · Hierarchical porous carbon (HPC) materials contain organized pores having different scales of diameters.

Web28 de out. de 2024 · Abstract. Hierarchical zeolites combine the intrinsic catalytic properties of microporous zeolites and the enhanced access and transport of the additional meso- and/or macroporous system. These materials are the most desirable catalysts and sorbents for industry and become a highly evolving field of important current interests. WebHierarchical Porosity. Figure 2.2 Classification of different types of porous materials, (a) A purely microporous zeolite is considered as a non-hierarchical system according to the single level of porosity, (b) Fragmentation of the zeolite into nanocrystals engenders a network of mesopores constituting the intercrystalline space, leading to an ... shane wireman
