Cost-effective fabrication of (g-C3N4 + Mo) added photostable ZnO thin films for enhanced visible light responsive photocatalytic dye degradation

In this study, the effect of Ba doping content on the photocatalytic activity of (Zn1‐xBaxO (ZBO); x=0 to 0.2) thin films is investigated. The efficiency of ZBO photocatalyst for the decolorization of Rhodamine B (RhB) is found to be optimum at x=0.1. The Zn0.9Ba0.1O film exhibits an efficiency of ≈ 96% at an irradiation time of 60 min. The high photocatalytic activity of Ba doped ZnO films is attributed to the high efficient generation and separation of photo‐induced charge carriers as evident from photocurrent measurements. Further, the texture and the oxygen vacancies favor the photocatalytic activity as suggested by the x‐ray diffraction (XRD), scanning electron microscope (SEM), x‐ray photoelectron spectroscopy (XPS), Raman spectroscopy and photoluminescence (PL) analysis. Moreover, the reusability test reveals that the photocatalyst performance remains for at least six consecutive cycles without significant change. The higher efficiency and outstanding reusability of Zn0.9Ba0.1O make it a potential candidate for photocatalytic applications.

It is a practical way to raise the efficiency of photocatalysis by using oxygen vacancy defect modified materials. In this experiment, a Z‐scheme BOA composite photocatalyst with defect structure was prepared by hydrothermal in situ precipitation method. The optimal ratio of 1.5 BOA showed excellent photocatalytic degradation performance for MO, TC and CIP under visible light irradiation, and maintained good structural stability and circulation rate after five cycles. The increased photocatalytic activity of the composite can be explained to the heterojunction interface‘s synergistic effects and the quicker electron hole transit rate caused by the surface oxygen vacancy defect. XPS and EPR confirmed the existence of anoxic structure in the composite, PL and photocurrent confirmed the high electron hole transfer rate. The active species that contributed to the degradation process were validated by the active species capture experiment and ESR. LC–MS speculated the possible degradation path of CIP. Finally speculated the reaction mechanism of Z‐scheme BOA composite photocatalyst. Using the anoxic structure of BiO2−X to form a Z‐scheme heterostructure with Ag3PO4, the oxygen vacancy as the electron capture center and active site is conducive to improving the photogenerated electron transfer rate, thereby improving the structural stability and photocatalytic performance of the complex.
