The syntheses of silica materials provide many experimental methods that introduce different assemblies of nanoporous silica structures. Silica nanoparticles, hollow silica shells, core/shell structures and porous silica materials are examples of structures that have been synthesized in research works. A standard procedure for producing silica nanomaterials uses the established sol-gel Stöber process. Other developed methods also include solvothermal and hydrothermal techniques to prepare amorphous and crystalline silica materials. A review of the different approaches such as self-template, hard template, and soft template are described to present particular strategies that have been adapted to fabricate silica nanomaterials. The composition of silica scaffolds can include organic and inorganic states of matter. These adaptations can be utilized to achieve certain configurations during post synthetic treatments such as calcination and etching. The morphology of cubic and spherical silica particles are also studied to analyze the synthetic factors regarding the formation of shapes. Here, silica microcubes are produced after secondary precipitation of silica onto silica nanospheres. Hollow silica microcubes with different shell thicknesses are fabricated from the mSiO2@mSiO2 cubic particles through including additional silicate precursors during synthesizing the external layer followed by etching in warm water. Porous silica structures are recognized categories of materials that are applied for nanoscale storage and transport purposes. In this study, hollow silica microcubes are applied in the X-ray catalyzed hydroxylation of coumarin-3-carboxylic acid. X-ray induced enhancement occurs at the Type 1 and Type 2 proximities. Type 1 is described to be at least 100 nm away from the nanoparticle interface while Type 2 is within 100 nm from the nanoparticle interface. This review investigates current and viable methods to synthesize and apply porous silica nano-/micro-structures for research analyses.

In this thesis project, the goals were to establish synthetic access to two types of mesoporous silica nanoparticles with different internal morphologies and determine whether a solid silica coating can effectively encapsulate charged paramagnetic contrast agents within the interiors of the mesoporous silica nanoparticles. Mesoporous silica nanoparticles (MSNs) were developed following a modified literature procedure. Details of how the incorporation of two swelling agents (including one not reported previously) is also presented. The viability of synthesizing the MSNs with and without the swelling agents was also assessed, and reasons for observed variations were discussed. Hollow mesoporous silica nanoparticles (hMSN) were also synthesized using a modified literature-based method which generally includes three steps: solid core synthesis, mesoporous shell deposition, and etching. A delayed-addition Stöber-based procedure for synthesizing the templating silica is also presented, improving size consistency from batch to batch. With evidence of solid silica being porous to water, both types of nanoparticles were solid silica-coated to effectively trap the load inside. An easily detectable surrogate dye with the same charge as the intended load was used for the studies. Several techniques were used to quantify surface silanol, assess amine functionalization, and evaluate the effectiveness of the coating procedure.

This work concerns the preparation of silica materials with hierarchical porosity for the encapsulation of molecules of interest in the field of drug delivery and as biocatalysts. In order to reach this goal, the nano-emulsions were chosen as templates for the macropores of the material because of the homogeneous and small size of the emulsion droplets (less than 100 nm). The system Remcopal 4/decane/water was investigated and the optimal conditions for which nano-emulsion is formed via the phase inversion methods were determined. Adding micelles to the nano-emulsions does not affect its stability and can form a network of mesopores organized with a hexagonal symmetry. Hybrid materials which are hierarchically porous materials where the organic phase is still present, were doped with ketoprofen to study its release, which proved to be pH sensitive. Moreover, the study of the release of ketoprofen from the meso-macroporous material indicates that it is assisted by the micelles which are solubilized in the release medium. The second objective of this work was to use these porous materials as a biocatalyst for biodiesel synthesis from colza oil. For this application it was necessary that the materials are resistant to immersion in aqueous media. The study of the hydrothermal stability shows that the calcined material has the best stability in boiling water. Moreover, the material can withstand up to 550 ° C, the structure undergoes only minor damages. We also used a dual-mesoporous silica material prepared from hydrogenated and fluorinated micelles coexisting in the same solution. Thermal and hydrothermal evaluation indicates that these materials have two different decay kinetics corresponding to each of the two matrices having different pore sizes. The immobilization of lipase Mml was studied on the meso-macroporous calcined material and the dual-mesoporous material. The adsorption isotherms were used to demonstrate that the dual-mesoporous material can encapsulate more enzymes than its meso-macroporous counterpart. On the other hand, the enzyme activity, evaluated by the transesterification reactions, is more important for the calcined meso-macroporous material.
