摘要

Skeletal gold nanocages (Au NCs) are synthesized and coated with TiO_2 layers (TiO_2-Au NCs). The TiO_2-Au NCs exhibit enhanced photodecomposition activity toward acetaldehyde under visible light (＞400 nm) illumination because hot electrons are generated over the Au NCs by local surface plasmon resonance (LSPR) and efficiently transported across the metal/semiconductor interface via the defect states of TiO_2.
