Structural Modifications of Carbon Nitride for Photocatalytic Applications


Structural Modifications of Carbon Nitride for Photocatalytic Applications

Ajay Kumar, Manisha Chandel, Manita Thakur

The current research on photocatalysis is totally focused on the designing and innovation of various low cost materials. For an efficient photocatalyst, there are some aspects which are to be assessed before practical use, such as optical activity, thermal and chemical stability, easy and availability of raw material, biocompatibility, etc. Fortunately, g-C3N4 offers most of these qualities to behave as a star photocatalyst. g-C3N4 could be easily prepared from low cost precursor materials such as urea, melamine, cyanimide and dicyandiamide by simple thermal treatment. Furthermore, larger surface area and two-dimensional planar conjugation structure of g-C3N4 can provide a large platform for anchoring various substrates. Various researchers have utilized g-C3N4 for varieties of applications such as green energy production, energy storage devices, biomedical application, wastewater treatment via photocatalysis and adsorption, photo sensors, etc. Although there are some disadvantages associated with use of g-C3N4 when utilized for various applications. To overcome such hitches various structural modifications have been applied to g-C3N4. The current chapter summarizes a wide mode of applications of g-C3N4 along with various structural modifications which were recently applied to improve the photocatalytic efficacy.
