Textured macro- and mesoporous alumina samples designed in the presence of different surfactant types
(Springer, 2014-07-01)
This work presents a method that enables the synthesis of porous alumina in the presence of different types of surfactant. The method is based on a sol-gel transition, using surfactants and droplets of a nonpolar phase as ...
Sulfated tin oxide with macro- and mesopores controlled using an integrated sol-gel and surfactant template route
(2019-12-20)
Sulfated tin oxide was synthesized by a sol-gel process and pores were formed in the ceramic powders using Pluronic F-127 as a soft template. Sulfate ions linked to the tin oxide promoted the formation of acid sites on the ...
Successful application of a commercial cationic surfactant mixture (benzalkonium chloride) as porosity stabilizer in porous carbons fabrication
(Elsevier Science, 2016-11)
Porous carbons (BSPCs) were obtained by carbonization of resorcinol-formaldehyde gels in the presence of cationic surfactants mixture (benzalkonium chloride) which act as porosity stabilizer. The application of an inexpensive ...
Micellization of CTAB in the presence of silicate anions and the exchange between bromide and silicate at the micelle surface: A step to understand the formation of mesoporous molecular sieves at extremely low surfactant and silicate concentrations
(Academic Press Inc Elsevier ScienceSan DiegoEUA, 2006)

Preparation of hierarchically structured porous aluminas by a dual soft template method
(Elsevier B.V., 2010-07-01)
A general and potentially easy method of synthesizing aluminas possessing hierarchical pore structure is presented in this paper. This method is based on the integration of the sol-gel process with micelles of poly(ethylene ...
Synthesis of Polystyrene Microspheres to be Used as Template in the Preparation of Hollow Spherical Materials: Study of the Operative Variables
(Elsevier, 2012-07)
Mono-disperse polystyrene (PS) spheres were synthesized. The styrene polymerization was carried out using 4,4´-azobis 4-cyanovaleric acid (ACVA) or potassium persulfate (KPS) as initiators in the presence of polyvinyl ...
