Abstract

A new method of monitoring the deposition of single layers of colloidal particles (10–200 nm in diameter) on a flat surface is described. We demonstrate that with a quartz crystal microbalance (QCM) it is possible to measure directly the addition of one colloidal monlayer of SiO2 particles onto an oxidized Al film, or onto a previously formed multilayer. This technique holds promise for the accurate modelling and control of catalyst preparation, e.g. for the deposition of washcoats, and other applications of monodispersed colloids.
