Abstract
The hydrolysis of tri-sec-butoxyaluminum in the presence of nonionic surfactants leads to mesoporous alumina molecular sieves with wormlike arrays of channels with uniform diameters in the range 2.4 – 4.7 nm, depending on the nature of the surfactant. Molecular sieves of this type are of interest as possible catalysts and catalyst supports. The transmission electron micrograph of an alumina of this type is shown on the right.
