AB  - A series of novel oxygen-rich bismuth oxychloride (Bi12O17Cl2) were synthesized 
      through a facile poly(vinyl pyrrolidone) (PVP)-assisted hydrothermal route. These 
      obtained Bi12O17Cl2 samples were characterized by various physicochemical 
      techniques. It was found that a proper addition amount of PVP could promote the 
      transformation of Bi12O17Cl2 morphology from irregular clusters to 
      three-dimensional hierarchical flower-like microspheres that were nominated as 
      sample BP2. As-synthesized samples were subjected to a photocatalytic degradation 
      of dye Rhodamine B (RhB) or 2,4-dichlorophenol (2,4-DCP) under visible light. 
      Among all candidates, the sample BP2 with a hierarchical flower-like morphology 
      showed the best degradation efficiency for RhB and 2,4-DCP. The apparent rate 
      constant of sample BP2 in terms of degradation of RhB was nearly 5.7 and 45 times 
      that of unmodified BP0 and N-TiO2. The enhanced photocatalytic performance could 
      be ascribed to synergetic effects including unique hierarchical morphologies, 
      large specific surface area, small particle size, good crystallinity, and 
      suitable band structures. A possible mechanism of catalytic degradation was 
      finally proposed basing upon the active species trapping experiments.
