Analytical high-resolution TEM study of supported gold catalysts: orientation relationship between Au particles and TiO2 supports

An analytical high-resolution TEM study was carried out for gold deposited on TiO2 (anatase and rutile) to obtain a structural insight into the unique catalytic properties of the system. Preferred orientations between Au particles and the TiO2 support were often observed and a model for the epitaxial orientation between the Au particles and anatase TiO2 was proposed. These results were consistent with the results calculated by the coincidence of reciprocal lattice point (CRLP) method.
