Sulfated zirconia (SZ) has been found to be catalytically active for the isomerization of n-butane at room temperature [1]. This discovery has led to numerous investigations into the catalyst; however, no consistent theories have been devised to satisfactorily explain its structure, acidity and reactivity [2]. In order to improve surface characterization, a model system consisting of a nanocrystalline SZ thin film supported on a silicon wafer has previously been developed [3, 4]. The films are prepared using an aqueous route via a self-assembled monolayer (SAM), in which the film thickness is accurately controlled by deposition time.
SZ thin films have been synthesized as described in [3, 4]. Successful formation of a SZ thin film has been verified by using XPS, SEM and HRTEM techniques.
