Abstract:
Semiconductor based photocatalysis is one of the effective techniques of AOPs for environmental remediation. In present work, the development of an efficient photocatalyst formed by coupling of ptype Bi2O3 and n-type ZnO is reported. The Bi2O3-ZnO heterostructures with 5, 10 and 15% Bi2O3 were synthesized by co-precipitation method. The prepared heterostructures were characterized by various advanced techniques including XRD, XPS, UV-Visible spectroscopy, FTIR, SEM and surface area measurement. The prepared ZnO and Bi2O3-ZnO heterostructures were tested as photocatalysts for photodegradation of dyes using mixed solution of rhodamine B and reactive yellow dyes. The 5% Bi2O3-ZnO heterostructure was found as most efficient photocatalyst with 93 and 91% photodegradation of rhodamine B and reactive yellow dyes, respectively, as given in Figure 1. It was found that incorporation of 5% Bi2O3 with ZnO enhanced the photocatalytic activity about 15 times towards photodegradation of dyes.
