S-scheme ZIF-8/Ag2S heterojunction photocatalyst for degradation of organic pollutant using batch and external loop airlift reactors

Efficient Rhodamine B removal by photocatalysis using polyacrylonitrile/Ag2S nanofibers prepared by combining electrospinning technology and facile gas–solid reaction

“…[12][13][14] Recently, Ag 2 S semiconductor has become an effective visible-light-driven photocatalyst because of its excellent properties such as high chemical stability and surface area, good promising thermoelectric and photoelectric properties, and narrow band gap. 15,16 However, most of the previous studies used the nanoparticle form of Ag 2 S which tends to agglomerate into large clusters and requires complicated filtration, separation, and recovery processes, so it is difficult to be applied in practice. Thus, immobilizing Ag 2 S nanoparticles (NPs) onto an inert support such as carbon-based materials would be a great idea.…”

“…There have been many heterogeneous photocatalytic materials that could be used to remove dyes in water such as nanoparticles 9–11 and magnetic nanocomposites 12–14 .
