The draining of industrial waste into natural water sources is creating severe destruction to the environment by contaminating the water. Here, 2D/2D nitrogen-doped g-C3N4/In2S3 nanocomposites (NGI) were developed by varying concentrations of Ngcn {337 mg (NGI-1), 675 mg (NGI-2) and 1350 mg (NGI-3), respectively} by simple polycondensation-reflux method. The remediation of organic pollutants from wastewaters was performed by as-prepared photocatalysts periodically. PXRD reveals the monoclinic and cubic structure of Ngcn and In2S3 respectively. FESEM and TEM images confirm the sheet-like morphology with the average size of ~ 500 nm whereas D-spacing values in SAED patterns resemble XRD peaks for both Ngcn and In2S3 respectively. Moreover, the XPS technique was performed to confirm the elemental compositions of Ngcn and In2S3 photocatalysts. The maximum pore size (20.44 nm) and pore volume (1.15 cc/g) of NGI-2 nanocomposite were observed by BET results. NGI-2 showed the maximum photodegradation efficiency ~ 99% in 10 min with photodegradation rate (0.141/min) that is ~ 2 folds than pristine indium sulfide (InS) and 8-folds than nitrogen-doped g-C3N4 (Ngcn). Moreover, NGI-2 showed a good adsorption capacity of 5.02 mg/g which is 2-folds than Ngcn. The enhanced adsorption capacity along with photocatalytic degradation of NGI-2 could be attributed to a high rate of electron-hole pair separation due to the combined effect of band gap, large surface area and interface formation. The industrial sewage analysis was also examined by NGI-2 and found significant photodegradation efficiency.
