A rod‐like g‐C 3 N 4 /ZnS composite was synthesized via a hydrothermal process using g‐C 3 N 4 , Zn(NO 3 ) 2 · 6H 2 O, thioglycolic acid, and thioacetamide as precursors under reflux conditions. The obtained products were characterized by X‐ray diffraction (XRD), scanning electron microscopy (SEM), transmission electron microscopy (TEM), UV/Vis absorption spectroscopy (UV), Fourier transform infrared spectroscopy (FTIR), Brunauer–Emmett–Teller (BET) analysis, inductively coupled plasma (ICP) spectroscopy, and photoluminescence (PL) spectroscopy. The amount of g‐C 3 N 4 was systematically varied, and it was found that the g‐C 3 N 4 content not only plays an important role in the formation of g‐C 3 N 4 /ZnS rod‐like composites but also the improvement of the photocurrent response. The photocatalytic experimental results indicated that the 10 wt.‐% g‐C 3 N 4 /ZnS nanocomposite enhances photocatalytic performance with 93.0 % decomposition of methyl orange (MO) after 100 min under simulated sunlight irradiation. This new composite is expected to show considerable potential in the treatment of wastewater containing organic pollutants.
