A Review on Green Synthesis of Silver Nanoparticles Conjugated with Activated Charcoal to form Silver-Charcoal Nanocomposites and its Applications in Water Filter Membrane
Authors
Abstract
The increasing interest to carbon and silver nanotechnology and its various
applications nowadays caught the attention of many researchers. In this review, the types of
plants used for green synthesis of silver nanoparticles and its antimicrobial activity against
different types of infectious agents were cited. This challenge boosts the interest of
researchers to promote a more eco-friendly way of synthesis of nanoparticles compared to the
present ones that can also potentially used in various fields of its application. Occurrence,
shape, morphology, and size of silver nanoparticles are also revealed with references.
Applications and mechanism of silver nanoparticles in water filtration membranes are also
highlighted with suitable references. As charcoal are considered as one of the significant filter
types capable of arresting microbial metabolism from odour causing, many articles related to
charcoal and its antibacterial mechanisms were reported in this review. Charcoal in water
filtration units or in membranes were also described emphasizing the role of activated carbon
or charcoal for preventing the growth of bacteria in water or potable water. As
nanocomposites are gaining more attention in the membrane filter production industries, in
this review, we focussed about the mechanism, synthesis, and application, including their
advantages and disadvantages, of charcoal, silver, and silver+ charcoal nanocomposites.
