AB  - A typical Z-scheme system is composed of two photocatalysts which generate two 
      sets of charge carriers and split water into H(2) and O(2) at different 
      locations. Scientists are struggling to enhance the efficiencies of these systems 
      by maximizing their light absorption, engineering more stable redox couples, and 
      discovering new O(2) and H(2) evolutions co-catalysts. In this work, Au decorated 
      WO(3)/g-C(3)N(4) Z-scheme nanocomposites are fabricated via wet-chemical and 
      photo-deposition methods. The nanocomposites are utilized in photocatalysis for 
      H(2) production and 2,4-dichlorophenol (2,4-DCP) degradation. It is investigated 
      that the optimized 4Au/6% WO(3)/CN nanocomposite is highly efficient for 
      production of 69.9 and 307.3 micromol h(-1) g(-1) H(2) gas, respectively, under 
      visible-light (lambda > 420 nm) and UV-visible illumination. Further, the fabricated 
      4Au/6% WO(3)/CN nanocomposite is significant (i.e., 100% degradation in 2 h) for 
      2,4-DCP degradation under visible light and highly stable in photocatalysis. A 
      significant 4.17% quantum efficiency is recorded for H(2) production at 
      wavelength 420 nm. This enhanced performance is attributed to the improved charge 
      separation and the surface plasmon resonance effect of Au nanoparticles. 
      Solid-state density functional theory simulations are performed to countercheck 
      and validate our experimental data. Positive surface formation energy, high 
      charge transfer, and strong non-bonding interaction via electrostatic forces 
      confirm the stability of 4Au/6% WO(3)/CN interface.
