Good Photocatalytic Performance

Good photocatalytic performance is demonstrated by Cu2O NPs directly loaded onto hydrothermally synthesized TiO2 NTs via photoreduction method conducted with a lower power UV lamp at room temp. This is due to narrowing bandgap and forming an internal electric field.
