AB  - Semiconductor nanoparticles are promising materials for light-driven processes 
      such as solar-fuel generation, photocatalytic pollutant remediation, and 
      solar-to-electricity conversion. Effective application of these materials 
      alongside light can assist in reducing the dependence on fossil-fuel driven 
      processes and aid in resolving critical environmental issues. However, severe 
      recombination of the photogenerated charge-carriers is a persistent bottleneck in 
      several semiconductors, particularly those that contain multiple cations. This 
      issue typically manifests in the form of reduced lifetime of the photoexcited 
      electrons-holes leading to a decrease in the quantum efficiency of various 
      light-driven applications. On the other hand, semiconducting oxides or sulfides, 
      coupled with reduced graphene oxide (RGO), have drawn a considerable interest 
      recently, partly because of the RGO enhancing charge separation and 
      transportation through its honeycomb sp(2) network structure. High electron 
      mobility, conductivity, surface area, and cost-effectiveness are the hallmark of 
      the RGO. This Mini-Review focuses on (1) examining the approach to the 
      integration of RGO with semiconductors to produce binary nanocomposites; (2) 
      insights into the microstructure interface, which plays a critical role in 
      leveraging charge transport; (3) key examples of RGO composites with oxide and 
      sulfide semiconductors with photocatalysis as application; and (4) strategies 
      that have to be pursued to fully leverage the benefit of RGO in 
      RGO/semiconductors to attain high photocatalytic activity for a sustainable 
      future. This Mini-Review focuses on areas requiring additional exploration to 
      fully understand the interfacial science of RGO and semiconductor, for clarity 
      regarding the interfacial stability between RGO and the semiconductor, electronic 
      coupling at the heterojunction, and morphological properties of the 
      nanocomposites. We believe that this Mini-Review will assist with streamlining 
      new directions toward the fabrication of RGO/semiconductor nanocomposites with 
      higher photocatalytic activity for solar-driven multifunctional applications.
