Abstract:
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 urn:x-wiley:23656549:media:slct201904943:slct201904943-math-0001 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.

THE VISION
THE MISSION
ABOUT I-STEM
It has always been the basic tenet of the Government of India, in generously funding R&D efforts at academic institutions over the years, that facilities established through such support be made available to those needing them and qualified to make use of them for their own research work

However, this was never easy or straightforward for, among other reasons, there was no ready source of information of what facility was available and where. Thanks to the Web, it is much easier today to have a national and regional “inventory of resources”, so as to match users with the resources they need, and to do all this in an efficient and transparent manner.

This can lead to a leap in R&D productivity and greatly enhance the effectiveness of public investment. This is the motivation behind I-STEM.
