采用一锅水热法合成了一种厚度为3.6 nm、比表面积为240 ~ 350 m(2)/g、表面高度分散1 ~ 2 nm的TbxOy纳米tio2纳米片（tb - tns）。负载的TbxOy纳米颗粒影响了tns的形态、结构和光学性质。XPS结果表明，Tb3+和Tb4+在tbtss中共存，负载TbxOy导致Ti和o的结合能发生变化，Ti3+的含量随着TbxOy纳米颗粒的负载量逐渐增加。荧光光谱和表面光电流谱结果表明，适量的TbxOy (
A visible-light-driven TbxOy loaded TiO2-oriented nanosheets (Tb-TNSs) of 3.6 nm thick and specific surface area of 240-350 m(2)/g provided with highly dispersed TbxOy nanoparticles of 1-2 nm over the surfaces were synthesized using a one-pot hydrothermal route. Loaded TbxOy nanoparticles influenced morphology, structure, and optical properties of the TNSs. The XPS results showed that Tb3+ and Tb4+ co-exist in Tb-TNSs, and loaded TbxOy resulted in changes in binding energies of Ti and O. The amount of Ti3+ increased gradually with the amount of loaded TbxOy nanoparticles. FL and surface photocurrent spectra results indicated that an appropriate amount of TbxOy (
