Encapsulation of CoS nanoparticles in PAN electrospun nanofibers: Effective and reusable catalyst for ammonia borane hydrolysis and dyes photodegradation

Electrospun polymeric nanofibers encapsulated with nanostructured materials and their applications: A review

“…Therefore, in recent years, new interest has been arised in developing new applications for electrospun composite NFs. Considering the most attractive features of electrospun composite NFs, including high porosity, large surface area, easy separation, reusability, nonleaching nanostructured materials, and photocorrosion resistance of encapsulated nanostructure materials, a variety of applications related to water treatment [118,121,123,124,126,127,129], antibactericidal [119,122], hydrogen production [121,127], magnetic nanocomposite [125,128,130], and microwave absorption [131] have been highlighted in this communication.…”

“…In recent years, interest in semiconductor photocatalysts has been increase due to their potential to utilize UV and visible light. In the areas, where ample amount of sunlight is available, use of sunlight driven photocatalysis will be economical and favorable as sunlight is free available and inexhaustible [121]. However, the application of semiconductors as photocatalyst for wastewater treatment is facing serried of technical challenges like development of photocatalyst with broader photoactivity range in visible as well solar light spectrum, separation difficulties after use, photocorrosion and loss of catalyst during use.…”

“…However, the application of semiconductors as photocatalyst for wastewater treatment is facing serried of technical challenges like development of photocatalyst with broader photoactivity range in visible as well solar light spectrum, separation difficulties after use, photocorrosion and loss of catalyst during use. To overcome these challenges to some extent, researchers have tried to develop new variety of photocatalyst in which photocatalyst nanostructures are enclosed in electrospun NFs [121,123,124].…”

“…At the same time holes generated at valence band react with hydroxyl groups (OH À ) or H 2 O on catalyst surface to yield OH radicals as strong oxidizing agent for the photodegradation of organic dyes (Fig. 7) [121].…”

“…Most of the reported NPs suffer from high aggregation, loss, and photocorrosion of NPs during harsh reaction to release hydrogen from AB. To avoid this problem, use of photocatalyst containing encapsulated semiconductor NPs in polymeric NFs (composite NFs) using electrospinning technique has a special interest for the production of hydrogen by water splitting or hydrolysis of AB [121,137].…”
