Atomic and Electronic Structures of Nano-Interface In Au/TiO_2 Catalyst-Electronic Microscopic Approach

摘要

The size of dependence of the catlytic property of the gold catalysts has been reported.It is espeically interesting that the catalytic property of gold suddenly changes to show a platinum-like behavior when the mean size of gold is below 2 nm.This phenomenon should be owing to the change of the electronic structure of the gold,however its detail has not been cleared yet.
