Preparation of hydrophobic MFI zeolites containing hierarchical micro-mesopores using seeds functionalized with octyltriethoxysilane
(2020-01-20)
In this work, we report the synthesis of hydrophobic MFI zeolites presenting a mesopore size distribution and high specific external area (∼288 m2 g−1), employing surface functionalization with octyltriethoxysilane (OTEOS). ...
Zirconia foams prepared by integration of the sol-gel method and dual soft template techniques
(Elsevier B.V., 2008-11-01)
This paper presents a new method to produce basic zirconium sulfate foams showing hierarchic porosity, based on a dual pores templating process by oil drops and gas bubbles dispersed into a hydrosol, followed by its fast ...

Hierarchical bioglass scaffolds: Introducing the "milky way" for templated bioceramics
(Royal Society of Chemistry, 2015-04)
Free standing hierarchical bioglass scaffolds were prepared by the ISISA (ice-segregation-induced self-assembly) method. Commercial low-cost precursors such as Ludox® HS-40 and cow milk were employed as the source of SiO2 ...
Synthesis of microporous/mesoporous core-shell materials with crystalline zeolitic shell and supported metal oxide silica core
(Royal Society of Chemistry, 2016-04)
An engineered material, possessing a hierarchical porosity in a shape selective manner, was synthesized by placing a microporous silicalite-1 shell over silica microspheres embedded with various guest species. Core materials ...
Síntese de materiais Micro/Mesoporosos hierárquicos com estrutura MFI
(Universidade Estadual Paulista (Unesp), 2018-02-23)
Este trabalho descreve o estudo de uma nova metodologia de síntese para obtenção de zeólitas MFI contendo uma estrutura hierárquica de poros. A porosidade hierárquica é uma propriedade que aumenta a acessibilidade dos ...
