Synthetic polymers have been widely applied in various commercial and household applications owing to their fascinating properties of low-cost, lightweight, and processability. However, increasing population and living standards and rising demand for non-biodegradable polymers have led to the accumulation of plastic pollution resulting in the current environmental crisis. Current waste management methods such as landfilling or incineration do not solve these environmental issues. On the other hand, recycling plastic waste is the most valuable strategy for dealing with waste as raw material for high-value products. One of such products is filter membranes. Polymer fiber membranes as masks in pandemics have been one of the most sought-after products in recent years. Some types of plastic waste became a material source for the development of filter materials, which could contribute to the protection of human health. Utilizing the simple, cheap, and industrially available technological solution is also needed. Given the number of advantages, electrospinning is such a beneficial solution. The electrospun polymer waste-based membranes show excellent filtration performance and can carry many other functionalities. Therefore, this review article presents a brief overview of electrospun nanofibrous membranes based on synthetic plastic waste and summarizes the filtration performance of such membranes. This review will discuss the future perspectives of electrospun membranes as well.

The unsustainability of the production of catalysts due to limited resources and higher energy demands makes it critical to explore and reengineer new catalytic materials for future applications. Woefully, the unrelenting demand for the metals/metal oxides increases both the financial and environmental cost, particularly in mining and synthesis, rendering consumption unsustainable in its current form. In this context, electrospinning offers a new template for designing sustainable ways of minimizing the higher loading of catalysts and recyclability. In this context, metals/metal oxide doped electrospun membranes have grasped a great scientific interest as sustainable catalysts due to their enhanced catalytic activity and synergistic structure-property relationship of the doped material and the matrix. More specifically, the selectivity arising from the electronic properties and quantum mechanical interactions at the nanoscale of metal/metal oxide nanoparticles coupled with interactions at the electrospun membrane interfaces lead to such enhanced properties. This review article summarizes the applications of metals/metal doped electrospun membranes in different aspects of catalysis, such as thermocatalysis, photocatalysis, organocatalysis and electrocatalysis, with a particular focus on their sustainability. Keywords: Sustainable catalysis, metal/metal oxide doped catalysts, electrospinning, organocatalysis, photocatalysis

“…Among the methods to produce nanofibres, electrospinning is a unique synthetic method that uses electrostatic forces, which produces nanofibres ranging from 40 to 200 nm in diameters [24]. Electrospinning requires five main components of apparatus, including a high voltage supply, a syringe to feed the polymer solution, a metal spinneret or a needle to transfer the polymer solution, a syringe pump to pump the polymer solution from the syringe reservoir, and a ground collector to collect the ejected polymer fibres [25]. It involves the extrusion of fibre by applying an electrical potential between a polymer droplet held at the end of the nozzle of the spinneret and the grounded collector plate [26].…”

Nanofibres have gained increasing attention due to their advantages of having a high porous structure, narrow pore size and distribution, and a high specific surface area. One of the most efficient techniques for producing nanofibres is via electrospinning. Nanofibres are currently being used in various fields, including water filtration. Although nanofibres possess the ability to filter various components, the fibres generally have a low mechanical strength that can mitigate the performance over time. Therefore, in overcoming this issue, several studies have focused on improving the strength of the nanofibre membranes for a water filtration application. This review discusses the advantages and challenges of nanofibres for water filtration membranes and summarises the methods to increase the strength of the membranes, including solvent vapour, thermal treatment, and chemical crosslinking.
