Bio‐Based Nanofibers Involved in Wastewater Treatment

Abstract

Studies involving bio‐based nanofibers are well utilized in the field of energy, catalysis, electronics, and environmental science. In this review, the importance of utilizing bio‐based materials for the development and optimization of multiplexed nanofibers and the modifications adopted to overcome the drawbacks of conventional electro‐spinning to facilitate better production rates, enhanced adsorption, and its potential in removing heavy metal ions, dyes, and other contaminants polluting the environment are highlighted. This work provides the readers the ability to understand the complexity in fabrication of bio‐based nanofibers focusing primarily on chitosan, cellulose, and protein‐based nanofibers and their mechanism toward quenching/degradation of water contaminants. In addition, it also provides the advantages of using bio‐based materials over synthetic materials for the development of nanofibers.

Multilayered Bio-Based Electrospun Membranes: A Potential Porous Media for Filtration Applications

“…The rapid development of industries has led to particulate matter pollution that poses serious threats to the global environment, resources, and public health. Polymeric membranes are attracting attention for their efficient filtration of pollutants and microorganisms from many resources such as water, air, food, and microbiological fluids because of their high mechanical strength, their chemical, thermal, and corrosion resistance, and their minimal production of harmful by-products (Gandavadi et al, 2019;Lv et al, 2019;Ma et al, 2019a). Among the different polymeric membranes, bio-based polymers, i.e., cellulose nanofibers (CNFs), cellulose nanocrystals (CNCs), chitosan, and protein-based nanofibers, all gleaned from renewable resources, have shown superior performance during the filtration of water and microbiological fluids (Charcosset, 2012;Lv et al, 2018).…”

Removal of metal ions using Chitosan based electro spun nanofibers: A review

“…They highlighted the use of biomaterials due to their ready availability, environmental friendliness aspects and resource efficiency. They also discussed various strategies like functionalization, incorporation of other natural and synthetic materials to improve the efficiency of nanofibers, which facilitates enhanced adsorption and the potential for removing heavy metal ions, dyes, and other contaminants polluting the environment [63].…”

Oxygen Reduction Reaction in the Field of Water Environment for Application of Nanomaterials

“…It is a type of composition or crystal of atoms, molecules, and macro systems. If one direction is at the nanometer level, it is called a two-dimensional nanomaterial, such as nanosheets [ 15 ] and nanomembranes [ 16 ]; if two directions reach the nanometer level, it is called nanomaterials, such as nanofiber [ 17 , 18 , 19 ], nanotube [ 20 ], and nanorod [ 21 ]; and if the three directions reach the nanometer level at the same time, it is called zero-dimensional nanomaterials, such as nanoparticles [ 22 ], quantum dots, etc. Three different geometrical structures of GR are shown in Figure 2 .…”
