The achievement of hierarchical zeolite templated carbons (ZTCs) is firstly reported through the use mesoporous zeolites as sacrificial scaffolds. achieved ZTCs feature both tailored microporosity and high degree mesoporosity allow hence to bridge gap between classical CMK-like materials. Mesoporosity from steamed was meticulously transcribed ZTC particles. featuring surfactant-templated allowe...
Surfactant-templating is one of the most versatile and useful techniques to implement mesoporous systems into solid materials. Various strategies based on various interactions between surfactants and solid precursors have been explored to produce new structures. Zeolites are invaluable as size- and shape-selective solid acid catalysts. Nevertheless, their micropores impose limitations on the ma...
TMU-10 treated at 300 °C under air efficiently promotes H 2 generation ambient temperature from NaBH 4 . The enhanced catalytic activity derives a higher density of Lewis acid sites and the mesoporosity.
Zeolite Y was prepared by a dense-gel method and subsequently modified either treatment with diethylamine (DEA), sodium hydroxide (NaOH) or disodium ethylenediaminetetraacetate (Na2H2EDTA), sequential (H4EDTA-NaOH H4EDTA-NaOH-Na2H2EDTA). Individual did not succeed in introducing mesoporosity the parent zeolite Y, while lead to formation of mesopores. After introduction Cu2+ ions, obtained mater...
Mesoporous Y zeolites were prepared comparatively using the bottom-up templating (with carbon nanotubes, CNTs, and nanocrystalline cellulose, NCC, as templates) top-down post-synthetic treatment sequential chemical alkaline treatment) methods characterised comprehensively various techniques. The relevant findings show that mesoporous with intercrystal mesoporosity by methods, NCC is more effect...
