and reduction of toxic pollutants to stable form. The weight percentage of 3% of
MoS 2 /rGO hybrid in composite, provided maximum results of complete conversion
of 4-NP to 4-AP in 18 minutes. Further increase of co-catalyst resulted in decrease in
results due to shielding effect, which is obstructing the light source on catalyst. The
CdS-MoS 2 /rGO nanocomposite possess flower-like morphology for hybrid, with
rGO sheets meshing adequately close with MoS 2 nanosheets (Peng et al. 2016).
