AB  - This research focused on immersion method synthesis of visible light active 
      salicylic acid (SA)-modified TiO2 nanotube array electrode and its 
      photoelectrocatalytic (PEC) activity. The SA-modified TiO2 nanotube array 
      electrode was synthesized by immersing in SA solution with an anodized TiO2 
      nanotube array electrode. Scanning electron microscope (SEM), X-ray diffraction 
      (XRD), X-ray photoelectron spectroscopy (XPS), infrared spectroscopy (IR), UV-vis 
      diffuse reflectance spectrum (DRS), and Surface photovoltage (SPV) were used to 
      characterize this electrode. It was found that SA-modified TiO2 nanotube array 
      electrode absorbed well into visible region and exhibited enhanced visible light 
      PEC activity on the degradation of p-nitrophenol (PNP). The degradation 
      efficiencies increased from 63 to 100% under UV light, and 79-100% under visible 
      light (lambda>400 nm), compared with TiO2 nanotube array electrode. The enhanced 
      PEC activity of SA-modified TiO2 nanotube array electrode was attributed to the 
      amount of surface hydroxyl groups introduced by SA-modification and the extension 
      of absorption wavelength range.
