Abstract:
In this paper, we report on the facile synthesis of graphitic carbon nitride (g-C3N4)-tin oxide (SnO2) nanohybrid as an efficient photocatalyst prepared via sol–gel method. SnO2 nanoparticles are point contacted with g-C3N4. The results of physio-chemical characterizations such as SEM-EDAX, XRD, BET, FT-IR and UV-DRS spectra reveal the successful formation and integration of nanohybrid. The photocatalytic activity has been studied by using methylene-blue as a model dye for degradation. It has been observed that the pseudo-first order rate constant was increased up to 1.78 times compared with pure SnO2. The enhanced photocatalytic activity was ascribed from the inhibition of electron–hole recombination where g-C3N4 nanosheets acts as an electron receiver from SnO2 via point contact. This mechanism is further verified via photoluminescence spectra. Our results prominently show new insights and potential applications of g-C3N4-SnO2 nanohybrids in the waste water treatment and environmental remediation sectors.

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.
