Abstract
The growth of pure-phase perovskites and spinels is reported using pulsed-spray evaporation chemical vapor deposition (CVD). Besides the near-bulk properties of 250 nm thick perovskites, an unusual surface confinement of charge transport was observed in ultrathin, < 10 nm, polycrystalline LaCoO3 films, resulting in an electrical resistivity that appears to be lower than that of a single crystal. Using doping strategy as a tool to tune the physicochemical properties of the spinel structure of cobalt oxide was demonstrated, enabling the establishment of direct correlations between its properties and catalytic activity. Iron doping of Co3O4 has enabled the control of the reducibility of the spinel with direct consequences on the catalytic oxidation of CO and the control of the abundance of basic adsorption sites, which affected the catalytic oxidation of ethanol.
