摘要: Abstract Mesoporous TiO 2 materials have been synthesized with the aid of benzyl alcohol (BA) as cosurfactant along an anionic surfactant sodium dodecyl sulfate (SDS) template/structure directing agent (SDA). The synthesis was carried out both and without use BA in presence or cationic (cetyltrimethyl ammonium bromide, CTAB) to optimize conditions. SDAs were removed from as-synthesized material through ethanol–acetate extraction by a newly developed borohydride reduction technique described herein. resulting characterized XRD, TEM, FE-SEM, nitrogen sorption, UV–visible FTIR spectroscopic tools. SDS assisted formation mesophase, whereas using alone CTAB SDA BA, no mesophase observed. These mesoporous showed very high surface area existence mesopores having broad pore size distributions. A model has proposed rationalize self-assembly (SDS mixtures templates.
