为了获得更好的可见光光催化性能，采用电子束掠射角沉积（GLAD）技术，在空气中退火，随后采用连续离子层吸收反应（SILAR）法制备了Ag2S偶联的TiO2纳米棒阵列（NRA）。研究了其光电化学和光催化降解橙子的性能。Ag2S在TiO2 NRA上的存在被观察到对可见光的响应具有显著的改善。这是由于Ag_2S的偶联可以显著提高光催化剂的短路光电流密度，提高光催化活性。
In order to obtain a better photocatalytic performance under visible light, Ag2S-coupled TiO2 nanorod arrays (NRAs) were prepared through the electron beam deposition with glancing angle deposition (GLAD) technique, annealing in air, followed by the successive ionic layer absorption and reaction (SILAR) method. The properties of the photoelectrochemical and photocatalytic degradation of methyl orange (MO) were thus conducted. The presence of Ag2S on TiO2 NRAs was observed to have a significant improvement on the response to visible light. It’s resulted from that Ag2S coupling can improve the short circuit photocurrent density and enhance the photocatalytic activity remarkably.
