The　ternary　In2O3-Ag-TiO2　composites　based　on　anatase　TiO2　nanotube　arrays　(TNTs)　were　synthesized　to　extend　the　light　responsive　region,　enhance　the　visible　light　absorption,　reduce　the　recombination　rate　of　charge　carriers　and　promote　the　efficiency　of　water　splitting　for　H-2　evolution.　Highly　ordered　TNTs　were　first　prepared　by　electrochemical　anodization　of　Ti　sheets.　Ag　nanoparticles　with　a　diameter　of　about　20　nm　were　then　uniformly　deposited　inside　and　on　the　orifice　of　the　TNTs.　In2O3　nanoparticles　synthesized　through　a　solvent-thermal　method　were　subsequently　modified　on　the　Ag-TNTs　using　an　ultrasound-assisted　electrophoresis　method.　In2O3-Ag-TNTs　composites　exhibited　enhanced　visible　light　absorption　and　photocurrent　when　compared　to　binary　Ag-TNTs　and　In2O3-TNTs.　As　a　result,　the　optimal　hydrogen　generation　rate　using　the　In2O3-Ag-TNTs　composite　under　visible　light　irradiation　was　1.92　mu　mol　cm(-2)　h(-1),　5　times　higher　than　that　of　the　pure　TNTs.
