Findings from Nankai University Provide New Insights into Interface Science (Synthesis of cubic Ia-3d mesoporous silica in anionic surfactant templating system with the aid of acetate)

By a News Reporter-Staff News Editor at Journal of Technology -- Investigators discuss new findings in Interface Science. According to news reporting out of Tianjin, People's Republic of China, by VerticalNews editors, research stated, "Mesoporous silica with three-dimensional (3D) bicontinuous cubic Ia-3d structure and fascinating caterpillar-like morphology was synthesized by using anionic surfactant N-lauroylsarcosine sodium (Sar-Na) as the template and 3-amionpropyltrimethoxysilane (APS) as the co-structure-directing agent (CSDA) with the aid of acetate. A phase transformation from high interfacial curvature 2D hexagonal to low interfacial curvature 3D cubic Ia-3d occurred in the presence of a proper amount of acetate."

Our news journalists obtained a quote from the research from Nankai University, "Other species of salts (excluding acetate) had the ability to induce the caterpillar-like morphology, but failed to induce the cubic Ia-3d mesostructure. Furthermore, [3-(2-aminoethyl)-aminopropyl]trimethoxysilane (DAPS) was also used as the CSDA to synthesize Ia-3d mesostructured silica under the aid of sodium acetate. After extraction of the anionic surfactants, amino and di-amine functionalized 3D bicontinuous cubic Ia-3d mesoporous silicas were obtained and used as supports to immobilize Pd nanoparticles for supported catalysts."

According to the news editors, the research concluded: "The catalytic activity of the catalysts was tested by catalytic hydrogenation of allyl alcohol."
