The conclusion will be helpful
Graphene-based    semiconductor    photocatalysts    have
attracted extensive attention for their potential in environmental
and energy-related applications. Although considerable progress
has been achieved, the studies in this ﬁeld are at the primary stage
and  further  developments  are required.  First,  as  an  essential
component of the composites, the synthesis of graphene is not yet
matured and the quality-control issues need to be addressed.
New  synthesis  methods  have  to  be  developed  for  preparing
high-quality graphene or graphene oxide sheets with high purity,
tunable sizes of layers, compositions and defects. Second, the
performance  of  graphene-based  semiconductor  composites  is
limited by the quantity of these composites and their
microstructures. Therefore, a more  careful design of  the
functional composites is required to obtain higher quality, more
uniform morphology on the nanoscale and better photocatalytic
properties. Third, the rapid development of material science and
technique in the past few years has resulted in the creation of
various advanced photocatalytic materials. Interesting properties
may  be  explored  by  combining  these  novel  photocatalysts
with graphene or graphene oxide sheets. Finally, the mechanisms
of photocatalytic enhancement by the graphene-based
semiconductor  composite  systems  are  partly  unclear.  For
example, whether the photocatalytic activity of TiO2–graphene
composites  is  truly  diﬀerent  from  other  TiO2–C  (activated
carbon, fullerenes, or carbon nanotubes) composite materials.
Furthermore, the explanation of photocatalytic activity by the
graphene  content  in  the  composites  is  still  controversial.
Therefore,  more  studies  are  needed  to  improve  the  general
understanding of the enhancement mechanism of photocatalysts
by graphene. Nevertheless, graphene-based semiconductor
composite photocatalysts are expected to be developed as robust
materials to address various environmental and energy-related
issues.
