Chemisorption on metal films on oxide surfaces

During the past year, great advances have been made in the preparation of smoother and more defect-free oxide surfaces. Metal particles have been prepared on these surfaces which are extremly well-defined with respect to particle thickness, lateral dimension, shape, electronic structure and energy. Chemisorption and catalytic reactions have been proven to depend on particle thickness, size and separation, and the nature of the oxide support surface; and these effects have been explained.
