Influence of Ag-Au microstructure on the photoelectrocatalytic performance of TiO2 nanotube array photocatalysts

The TiO2 NTs/Ag-Au and TiO2 NTs/Ag@Au were prepared by UV reduction and displacement reaction, respectively. Results indicated that the plasmonic photocatalysts exhibited excellent photoelectrocatalytic removal efficiency of MO dye molecule and Cr(VI) under solar illumination.134
