AB  - Surface functionalization and shape modifications are the key strategies being 
      utilized to overcome the limitations of semiconductors in advanced oxidation 
      processes (AOP). Herein, the uniform alpha-Fe(2)O(3) nanocrystals (alpha-Fe(2)O(3)-NCs) 
      were effectively synthesized via a simple solvothermal route. Meanwhile, the 
      sulfonic acid functionalization (SAF) and the impregnation of alpha-Fe(2)O(3)-NCs on 
      g-C(3)N(4) (alpha-Fe(2)O(3)-NCs@CN-SAF) were achieved through complete solvent 
      evaporation technique. The surface functionalization of the sulfonic acid group 
      on g-C(3)N(4) accelerates the faster migration of electrons to the surface owing 
      to robust electronegativity. The incorporation of alpha-Fe(2)O(3)-NCs with CN-SAF 
      significantly enhances the optoelectronic properties, ultrafast spatial charge 
      separation, and rapid charge transportation. The alpha-Fe(2)O(3)-HPs@CN-SAF and 
      alpha-Fe(2)O(3)-NPs@CN-SAF nanocomposites attained 97.41% and 93.64% of Cr (VI) 
      photoreduction in 10 min, respectively. The photocatalytic efficiency of 
      alpha-Fe(2)O(3)-NCs@CN-SAF nanocomposite is 2.4 and 2.1 times higher than that of 
      pure g-C(3)N(4) and alpha-Fe(2)O(3), respectively. Besides, the XPS, PEC and 
      recycling experiments confirm the excellent photo-induced charge separation via 
      Z-scheme heterostructure and cyclic stability of alpha-Fe(2)O(3)-NCs@CN-SAF 
      nanocomposites.
