Survey of graphene-based nanotechnologies

In recent years, graphene-based nanotechnologies are gaining much attention in the field of environmental and energy application. Due to its unique physicochemical properties such as high surface area, chemical stability, thermal conductivity, mechanical strength, and electron mobility, it can be used as a novel and enhanced material to address environmental and energy-related problems around the globe. It can be used as a novel material in environmental remediation (as a sorbent or photocatalytic material, in next-generation water treatment and desalination membranes, and as electrode materials for contaminant monitoring) and in energy applications (as batteries and supercapacitors for energy storage, fuel cells for energy conversion, catalysis, and sensing applications). A summary of recent information obtained using various applications of graphene-based nanotechnologies in different fields have been included in the discussion.
