Distinguishing Localized Surface Plasmon Resonance and Schottky Junction of Au-Cu2O Composites by Their Molecular Spacer Dependence

, 2014
The surface plasmon resonance (SPR) and Schottky effects are important photocatalytic activity boosters in metallic cocatalyst/photocatalyst systems, but it is difficult Cu2O composite in conjunction with UV and visible-light to differentiate them.
