Research Abstract

We made Au/SrTiO3 nano-hetero catalysts by the vacuum evaporation method (VE) in order to create new nano-hetero interfaces and characterized in nano-scale by high resolution electron microscopy (HREM) and electron holography. Au particles with the size over 2nm were deposited on SrTiO3 (001) and (011) planes with no orientation relationship in spite of the small mismatch of lattice constant. The mean inner potential of the Au nano particles on SrTiO3 also exhibit the size dependence. When the size of Au particle is smaller than 4nm, the mean inner potential of Au increased gradually as the size decreases. When the size is smaller than 3nm, the mean inner potential of the Au is over 35V.
