Reduced Graphene Oxide (RGO)-Based
Nanocatalyst for Inhibition of Pathogenic
Bacteria Toward Enhancement of Water
Purification
Shubhanwita Saha, Debashis Roy, and Chiranjib Bhattacharjee
Abstract Over the last few decades, various research concepts have been developed
to inhibit the growth of waterborne pathogenic bacteria. Among them, antibacterial
agent synthesis and application in water disinfection is one of the major challenges,
nowadays. It was observed that metal nanoparticles, such as Zn, Ag, Ti, Fe, or metalderived nanomaterials exhibited enhanced catalytic effect for water disinfection. The
use of graphene or R–GO as a support material for the dispersion of metal nanoparticles provides new ways to develop advanced, cost-effective catalyst materials for
the enhanced catalytic reaction. It is an attempt to generate a general overview
regarding the role of graphene and RGO-based composites as disinfectant agents
against waterborne pathogens.

1 Introduction
At present, the environment is getting affected by several effluences, harmful wastes,
contaminants, among them, water pollution is one of the major problems that affected
the natural habitat of the living being, directly. As per the report of WHO in 2015,
almost 1.1 billion people were affected by the drinking water crisis caused by
several environmental and climatic concerns, increasing population and higher cost
of drinking water (Anjum et al. 2016). To get rid of the problem of water crisis,
several projects have been launched all over the world. In our country, “Namami
