AB  - Due to integrated advances in photoelectrochemical (PEC) functionalities for 
      environment detection applications, one-dimensional (1D) TiO(2) nanostructures 
      provide a new strategy (PEC sensors) towards organics detection in wastewater. 
      However, the unidealized selectivity to the oxidation of water and organics 
      limits the PEC detection performance. Herein, we designed a ternary photoanode 
      consisting of Ag(2)O-AgBiO(3)/TiO(2) nanotube arrays (NTAs) to solve this issue 
      by using a facile one-step precipitation reaction. High oxidation capacity for 
      organics is achieved by regulating the surface free radicals properly through the 
      heterostructure formed between the interface of TiO(2) and AgBiO(3). More 
      importantly, as a trap for electron capture, Ag(2)O in this ternary system could 
      not only further improve the separation efficiency of charge carriers, but also 
      capture electrons transferred to the TiO(2) conduction band, thus reducing the 
      electrons transferred to the external circuit and the corresponding background 
      photocurrent when detecting organics. As a result, the reconstructed TiO(2) NTAs 
      decrease their photocurrent response to water and enhance their response to 
      organics, thus presenting lower oxidation activity to water and higher activity 
      to organics, that is, highly selective oxidation characteristics. This work 
      provides more insights into the impact of charge transfer and surface free 
      radicals on developing promising and efficient PEC sensors for organics.
