Introduction
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 describe the nature of the active sites [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]. The present work addresses two issues: the role of the atmosphere during thermal treatment and the validation of the model through demonstration of its reactivity towards n-butane.
