Nitrogen-doped g-C₃N₄/CoS nanocomposites have been synthesized using a facile polycondensation-hydrothermal method and showed improved photocatalytic activity for the degradation of MB dye and industrial real samples with good photostability.

Numerous scholars in the scientific and management areas have been overly focused on contemporary breakthroughs in two-dimensional objects for multiple prospective applications. Photochemical and electrocatalytic functions of integrated circuits associated with multi-component tools have been enhanced by designing the macro- and microstructures of the building blocks. Therefore, the current research attempts to explore a larger spectrum of layered graphitic carbon nitrides (g-C₃N₄) and their derivatives as an efficient catalyst. By executing systematic manufacturing, optimization, and evaluation of its relevance towards astonishing energy storage devices, adsorption chemistry, and remediation, many researchers have focused on the coupling of such 2D carbon nitrides combined with suitable elementals. Hybrid carbon nitrides have been promoted as reliable 2D combinations for the enhanced electrophotocatalytic functionalities, proved by experimental observations and research outputs. By appreciating the modified structural, surface, and physicochemical characteristics of the carbon nitrides, we aim to report a systematic overview of the g-C₃N₄ materials for the application of energy storages and environments. It has altered energy band gap, thermal stability, remarkable dimensional texturing, and electrochemistry, and therefore detailed studies are highlighted by discussing the chemical architectures and atomic alternation of g-C₃N₄ (2D) structures.

The draining of industrial waste into natural water sources is creating severe destruction to the environment by contaminating water. To control water pollution, many physical and chemical schemes have been applied to degrade organic and industrial wastewater. Here, we have developed 2D/2D nitrogen-doped g-C₃N₄/In₂S₃ nanocomposites [NGI], which exhibit high surface area and visible light photocatalysis with improved photocatalytic activity by varying the weight ratios of NGI. NGI-2 showed the maximum photocatalytic activity ~ 99 % in 10 min with maximum photodegradation rate which is around 2, 8-fold than indium sulfide (InS), nitrogen-doped g-C₃N₄ (Ngcn) by degrading MB dye. Moreover, NGI-2 showed a good adsorption capacity of 5.02 mg/g which is 2-fold 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 and a wide range of visible light regions. The industrial sewage analysis was examined by NGI-2 and found significant photodegradation efficiency.
