The above discussions well demonstrate that tailored architecture of
heterostructure offers superior functionalities in photocatalytic degradation of pollutants, abatement of antibiotics, and microbial disinfection. The detailed description
of the characterization techniques analogous to photocatalysis surmounts Cu 2 O as a
competent visible light-driven photocatalyst.
2.4 Conclusions
Benefiting from the feature of utilizing solar energy spectrum, photocatalysis ignites
a boom in wastewater remediation technologies. With invaluable development in
search of a novel visible light-driven photocatalyst, g-C 3 N 4 was found to be widely
used in large-scale applications. Exploiting the inherent properties of g-C 3 N 4 , it has
significantly gained platform as a robustly efficient photocatalyst. Nevertheless, it is
accompanied with certain limitations such as large band gap (2.7 eV), inefficient
absorption of solar light, and rapid recombination of charge carriers. Hence, for
designing a robustly active photocatalyst with improved properties, metal oxides
have been well explored. α-Fe 2 O 3 possess outstanding photocatalytic ability with
Fig. 2.12 XPS spectra of (a) Cu (2p), (b) C (1 s), (c) N (1 s) region in g-C 3 N 4 /Cu 2 O photocatalyst.
