采用真空辅助浸渍法制备了负载金纳米粒子的新型Au@TNT催化剂。在可见光下，Au@TNT催化剂的光催化分解水的活性是Au/TNT催化剂的2倍，大部分金纳米粒子分布在TNT的外表面。活性的提高归因于TNT的限制，它能有效地减小金催化剂的颗粒尺寸，并调节金催化剂的电子态。
A novel Au@TNT catalyst, with gold nano-particles (NPs) entrapped in TiO2 nanotube (TNT), was prepared by a vacuum assisted-impregnation route. For the photocatalytic water splitting under visible light, the Au@TNT catalyst presented 2 times higher activity than the Au/TNT with most part of gold NPs on the outer surface of TNT. The enhanced activity can be ascribed to the confinement of TNT which can effectively decreases the particle size and modulates the electronic state of gold catalyst.Graphical Abstract
