“…Monolithic meso/macroporous dual silica materials, with bimodal pore size distribution and well-controlled macroscopic morphology, have attracted a great deal of attention in the past decade because they combine the advantages of high specific surface with the accessible diffusion pathways associated with macroporous structures . The dual properties of these materials have stimulated research for applications that include catalytic supports, filters, chromatographic adsorbents, structural materials, and more recently enzyme-based biodiesel production, fuel cells or energy storage. , However, despite increasing research effort, the synthesis of large meso/macroporous monoliths, with ordered mesopores, remains a challenge not only because of inherent chemical incompatibilities in the precursor solution and the need for template removal, but also due to shrinkage during drying. Since mesoporous materials, such as hexagonal ordered MCM-41, were discovered by Mobil Corporation scientists in 1992, , surfactant-templated synthetic procedures have been extensively studied. The use of surfactant self-assemblies, in one-step methods, has been recognized as a very useful method for controlling morphology of mesoporous materials with ordered pores.…”

“…The particles of metal oxides such as TiO 2 can be used as sorbents without surface modification due to the presence of different types of titanol groups (Ti-OH). However, to increase their applicability and to modify their retention properties, the surface of such materials can be altered with immobilized organic phases to promote the interactions between the solid surface and organic molecules, such as van der Waals interactions, electrostatic attraction, donor-acceptor interactions, and chemisorption [31]. Various organic compounds can be incorporated within the gel network via chemical bonds by the copolymerization of organic and inorganic precursors, for sol-gel processing.…”

“…In the past decade, materials with dual meso- and macroporous structures (with bimodal pore size distributions) have attracted a great deal of attention because they combine the advantages of high specific surface areas with the good diffusion properties associated with macropores. Because of these dual properties, meso/macroporous materials are attracting widespread interest in many industrial applications, including chromatographic adsorbents separation processes , and photocatalysis . Other novel applications include fuel cells energy storage , or heterogeneous catalysis for biodiesel production …”
