Paramasivam Shanmugam, Balaji Parasuraman, … A. Given the long forecast era of the Sun, solar energy is also considered the ultimate renewable source that can be harvested on the planet, Earth [ 2 , 3 ]. The unending and discontinuous nature of this energy source, however, presents key challenges in relationships of harvesting, storage, and utilization [ 4 ]. At the moment, there are a measure of technologies in place that may be used to face them. Solar energy can be flexibly gathered, transformed and kept in the form of heat, which can either distribute heat to residence or be further converted into electricity, as well as into other forms of energy [ 5 ]. The most innovative investigated technologies concerning solar photon gaining may be on those by the photocatalysis, as described by Edmond Becquerel, [ 5 ]. Predominantly, wastewater is the major source of pollution, specifically, wastewater produced due to chemical industrialization, because this wastewater contains pronounced concentration of large organic fragments which are tremendously poisonous and carcinogenic in nature [ 3 ]. Previously, the environmental remediation technology which comprises of adsorption, biological oxidation, chemical oxidation, and incineration has been used in the treatment of all types of organic and toxic wastewater and also has its effective application in solar energy utilization, environmental treatment, and biomedical and sensing applications.

Graphitic carbon nitride g-C 3 N 4 is a family of carbon nitride compounds with a general formula near to C 3 N 4 albeit typically with non-zero amounts of hydrogen and two major substructures based on heptazine and poly triazine imide units which, depending on reaction conditions, exhibit different degrees of condensation , properties and reactivities. Graphitic carbon nitride can be made by polymerization of cyanamide , dicyandiamide or melamine. The firstly formed polymeric C 3 N 4 structure, melon , with pendant amino groups , is a highly ordered polymer. Further reaction leads to more condensed and less defective C 3 N 4 species, based on tri-s-triazine C 6 N 7 units as elementary building blocks. Alumina favored the deposition of the graphitic carbon nitrides layers on the exposed surface. This method can be assimilated to an in situ chemical vapor deposition CVD.

In summary, the unfeasible applications in wastewater and environmental pollution of most of the utmost well-versed photocatalysts is due to some of their demerit deterrents which includes, high cost, small scale, little photocatalytic activity, and thought-provoking recycle. The main factor limiting the photocatalytic activity of pristine g-C 3 N 4 is its bulk structure, resulting in its small specific surface area and few active sites, which prolongs the transfer path of photogenerated electrons, thus accelerates the photogenerated charge carriers compound odds.
