A New Synthesis of Mesoporous MSU-X Silica Controlled by a Two-Step Pathway

Boissière, Cédric, Larbot, André, van der Lee, Arie, Kooyman, Patricia J., Prouzet, Eric·2000·Chemistry of Materials

Abstract

In the field of micelle templated structures (MTS), the MSU-X family of mesoporous silica is obtained by using nonionic poly(ethylene oxide)-based surfactants. We show that the microstructure of these materials is highly dependent on the initial pH conditions and that a first assembly step, using a mild acidity, which allowed us to obtain a stable solution containing micellar hybrid objects made of both surfactant micelles and small silica oligomers, can be determined in the 2−4 pH range. The second step of the synthesis consists of the condensation of the silica particles and can be performed in two different ways. Either the pH of the stable solution is increased to neutral values or small amounts of fluoride are added. With the second method both the nanostructure and the particle morphology are better controlled. This novel two-step synthesis leads in addition to hexagonal pore framework when assembly molecules such as Tween 60 or block copolymer Pluronic P123 are used as assembly agents.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
