Abstract
In recent years, physicists, chemists and engineers
have focused their research on the design of new
functional materials. In the synthesis and control of
materials in nanometer dimensions, the aim is
currently directed towards the development of systems
and devices that take advantage of chemical properties
and physical principles, where their causes lie in the
nanometer scale. Although there are numerous
investigations about the synthesis of mesoporous
materials from inorganic silicon salt, for example the
synthesis of SBA-3.
Ting et al [1] studied the synthesis of SBA-1; they
obtained mesoporous SBA-1 with cubic structures,
with a high porous system, by utilizing agents’ routers
short chain structure such as the dodecyltrimethyl ammonium chloride.
Recent research also showed that the formation of
mesophases is affected by the presence of the counter ions and templates or surfactants can adopt a
mesophase or other phases. So, Che et al. [2] found a
phase shift 2D-hexagonal cubes from P6mm to Pm3n.
We have published results for synthesis of SBA-3 with
silica gel as silica source; we have found that the
formation of mesophase is function of NaOH
concentration in the dissolutions of silica gel. The
influence of reaction temperature, time and NaOH
concentration was investigated. During studies for the
best synthesis conditions for synthesis of SBA-3, we
also obtained SBA-1 and SBA-7 mesoporous materials.
