Microporous and Mesoporous Materials

Noemi Linares a , Ana M. E-mail: j. E-mail: joaquin. Alternative energy technologies are greatly hindered by significant limitations in materials science. From low activity to poor stability, and from mineral scarcity to high cost, the current materials are not able to cope with the significant challenges of clean energy technologies.

Handbook of Ecomaterials pp Cite as. This chapter will attempt to describe microporous and mesoporous materials, such as zeolites, and ordered mesoporous materials, which are versatile solids that are used for the environmental remediation and energetic efficiency and the applications in wastewater treatment and nuclear waste, purification and separation, medicine and catalysis. These materials are constructed from tetrahedral units, TO 4 where T is silicon and aluminum, usually , which are usually obtained from commercial sources. Furthermore, strategies and green approaches are described to contribute to the reduction of the cost production using cheaper and renewable raw materials such as rice husk, diatoms, coal ash, and clay minerals, which are potential and attractive sources of silicon and aluminum for the synthesis of zeolite and ordered mesoporous materials.

Microporous and Mesoporous Materials covers novel and significant aspects of porous solids classified as either microporous pore size up to 2 nm or mesoporous pore size 2 to 50 nm. The porosity should have a specific impact on the material properties or application. Both natural and synthetic porous materials are within the scope of the journal. The journal publishes original research papers, short communications, review articles and letters to the editor. Textural porosity and the generation of activated carbons by means of conventional methods are not within scope. However, both natural and synthetic porous materials are within the scope of the journal.

Guide for Authors

Silicate mesoporous materials have received widespread interest because of their potential applications as supports for catalysis, separation, selective adsorption, novel functional materials, and use as hosts to confine guest molecules, due to their extremely high surface areas combined with large and uniform pore sizes. Over time a constant demand has developed for larger pores with well-defined pore structures. Silicate materials, with well-defined pore sizes of about 2. Instead of using small organic molecules as templating compounds, as in the case of zeolites, long chain surfactant molecules were employed as the structure-directing agent during the synthesis of these highly ordered materials. The structure, composition, and pore size of these materials can be tailored during synthesis by variation of the reactant stoichiometry, the nature of the surfactant molecule, the auxiliary chemicals, the reaction conditions, or by post-synthesis functionalization techniques.

SBA has been successfully synthesized from ash of brickyard with the surface area of It can be used in environmental treatment for adsorption and separation [ 2 , 3 ], as a support material for catalysts [ 4 , 5 ] and as a template for the production of ordered mesoporous carbon [ 6 ]. SBA is usually synthesized in a cooperative self-assembly process under acidic conditions using the triblock copolymer pluronic EO 20 PO 70 EO 20 as template and tetraethoxysilane TEOS as the silica source [ 1 — 7 ]. However, high cost of complex TEOS processing motivates the development of alternative silica source. In this paper, the ash of brickyards was used as the silica precursor for preparation of mesoporous silica SBA because its main component was the rice husk ash that has high silica content. In Vietnam, the rice husk ash of brickyards is an abundantly available waste material; therefore, SBA synthesized by using rice husk ash as the silica source will bring economic efficiency.
