Summary: In this study, a novel photocatalyst consisting of nano-sized zinc and cobalt phthalocyanines (MPc) anchored on polyacrylonitrile (PAN) nanofibers was successfully synthesized using an innovative solution blow spinning (SBS) method. The resulting composite showed highly efficient degradation of methylene blue (MB) and the presence of TiO2 did not affect the photodegradation process. Moreover, the recyclability of the photocatalyst was achieved with minimal changes due to its stable macroscopic structure and flexibility.

Summary: Particulate matter air pollution and volatile organic compounds from fossil fuels and wildfires cause significant damage to health and the environment. Advances in air filtration technology are necessary to mitigate aerosol hazards. This study explores the potential benefits of producing nonwoven air filtration media using electrospinning and stabilizing polyacrylonitrile fibers, showing promising results that the electrospun media can meet the performance criteria of high-efficiency particulate air (HEPA) filter media, and even exceed it under certain conditions. Therefore, electrospun and stabilized nonwoven fibrous media are suggested as alternatives to traditionally manufactured HEPA media, with the potential to benefit air filtration technology and reduce particulate matter-related hazards.

Summary: Semiconductor materials have great potential as photocatalysts. In this study, a synthesis method combining electrospinning technique and SILAR reaction was used to prepare BiOI/CNFs photocatalytic material. The results showed that BiOI/CNFs had a much higher degradation rate of methyl orange under visible light compared to pure BiOI, due to the conductive CNFs improving the separation and transformation of photogenerated charges. Moreover, the fabricated BiOI/CNFs could be easily recycled due to their ultra-long one-dimensional nano-structural property.
