采用沉积-沉淀法在固定负载量下制备了不同粒径、接触良好的TiO 2负载Au纳米粒子（Au/TiO 2）。利用与Au具有特异性相互作用的S/S-2-作为氧化还原探针，测定了TiO_2负载Au纳米粒子在光稳态（E-F '）下的费米能。E-F'值随着Au NPs的平均尺寸（d）在3.0增加而增加
TiO2 particle-supported Au nanoparticles (NPs) with varying sizes and good contact (Au/TiO2) were prepared under a constant loading amount by the deposition-precipitation method. The Fermi energy of Au NPs loaded on TiO2 at the photostationary state (E-F') was determined in water by the use of S/S-2-having specific interaction with Au as a redox probe. The E-F' value goes up as the mean size of Au NPs (d) increases at 3.0
