Graphitic Carbon Nitride/Metal Oxides Nanocomposites and Their Applications in Engineering

Abstract

In recent decades, an intriguing two-dimensional polymeric graphitic carbon nitride has drawn significant multidisciplinary research consideration due to its captivating properties. It is an intriguing earth abundant, low cost, indirect semiconductor having fascinating layered structure similar to graphite with bandgap (2.7 eV), high physiochemical stability and visible-light absorption ability. So, it acts like a visible light driven photocatalyst. However, g-C3N4 in its pure form possesses few constraints like quick recombination of photogenerated electron-hole pairs, poor electrical conductivity and serious irreversible capacity loss which hinders its practical applications. Various categories of g-C3N4 based materials with improved performance were therefore extensively studied over the past few years. This chapter primarily presents g-C3N4 based composite materials including carbon/g-C3N4, metal/g-C3N4 and especially an elaborate discussion about metal oxide-graphitic carbon nitride composites and their applications in various aspects of engineering. In addition, it also includes historical development, future prospects and challenges regarding g-C3N4 and their composites for practical applications.
