AB  - Graphitic carbon nitride (g-C(3)N(4)) is a visible light active semiconductor. 
      However, low conductivity and high recombination rate of photogenerated electrons 
      and holes limit its application in photocatalysis. In this work, we design and 
      synthesize hierarchically porous zinc oxide/graphitic carbon nitride 
      (ZnO/g-C(3)N(4)) microspheres with type-II heterojunction to effectively degrade 
      rhodamine B (RhB) via increasing the charge-separation efficiency. The 
      ultraviolet-visible (UV-Vis) absorption spectra, Mott-Schottky plots and valence 
      band X-ray photoelectron spectroscope confirm the formation of type-II 
      heterojunction between ZnO nanocrystals and g-C(3)N(4) nanosheets. As a result, 
      the 1.5-ZnO/g-C(3)N(4) composite (the mass ratio of zinc acetate dihydrate to 
      g-C(3)N(4) is 1.5) exhibits the highest photocatalytic activity with good 
      stability and higher photocatalytic degradation rate comparing to pure g-C(3)N(4) 
      and pure ZnO. In addition, our results confirm that O(2)(-) and h(+) are the main 
      active species for ZnO/g-C(3)N(4) in degradation of RhB.
