The FE-SEM analysis shown in (Figure ) depicts a homogenously distributed nanorods-like structure of CdS with a particle length of about 81.93 nm (Figure ). It has been shown that the morphology of the photocatalyst, which is still a nanorods, is unaffected by the addition of Spinacia oleracea to CdS. An additional layer has been found made of Spinacia oleracea-derived carbon on the CdS nanorods (Figure -II). HR-TEM analysis of CdS and SO-CdS revealed clear lattice fringes with an inter-planar distance of 0.34 nm and 0.28 nm, respectively, corresponding to the (100) and ( ) planes of CdS. The morphology and average size of the SO-CdS nanorods were detected by HR-TEM (Figures and). SO added to the CdS nanorods caused the surface of the photocatalyst material to wrinkle more than that of the pristine CdS nanorods (Figure -II) . This was caused by the thermal shrinkage of the carbon material.
