One-Step Synthesis of Carbon Nitride Nanosheets for Photoremediation of Toxic Organic Dyes Waste in Aquatic Environment

Graphitic Carbon nitride ( g-C 3 N 4 ) has been taking the attention of scientists because of its potential applications as a catalyst for organic synthesis, electrodes, photocatalyst, and hydrogen storage material. The g-C 3 N 4  has also excellent chemical stability, special optical characteristics, and high thermal stability. Moreover, it only consists of carbon and nitrogen elements that make it safer for the environment than metal-based catalysts. Various techniques have been introduced to improve g-C 3 N 4  photocatalytic efficiency as a combination with other semiconductors and the modification of morphology like porous g-C 3 N 4  or nanostructures g-C 3 N 4 . When compared with g-C 3 N 4  bulk, g-C 3 N 4  Nanosheets have many advantages including high efficiency, low cost, environmentally friendly, and easy to produce on a large scale.  This review contains an overview of the one-step synthesis method from melamine and ammonium chloride for g-C 3 N 4  nanosheets as well as characteristics  and potential applications in dyes photoremediation.
