Photocatalytic degradation of methylene blue using polyaniline-based silver-doped zinc sulfide (PANI-Ag/ZnS) composites

Construction of PANI‐ZnFe2O4/FAC materials with fly ash cenospheres beads as a carrier to enhance the degradation of Methylene Blue

“…This may be due to the fact that in an acidic environment, H + in solution competes with the cationic dye MB for the active site, resulting in a decrease in MB degradation [53] . An increase in pH in solution (pH>8) the negatively charged surface of the photocatalyst will repel OH‐ ions, resulting in a decrease in photocatalytic efficiency [54] . The effect of different initial concentrations on methylene blue is shown in Figure d. The degradation rate tends to decrease with increasing MB concentration.…”

Structurally colored aramid fabric construction and its application as a recyclable photonic catalyst

“…Moreover, ZnS as a promising n-type semiconductor has excellent photocatalytic properties. 23,28,29 In addition, PCs have a slow photon effect 30 which may increase the photocatalytic efficiency of the photocatalytic reaction. Thus, the photocatalytic properties of PC-coated aramid fabrics were further investigated systematically.…”

Quantum dot decorated polyaniline plastic as a multifunctional nanocomposite: experimental and theoretical approach

“…24 Mazhar et al have created a silver-doped zinc sulde based on polyaniline (PANI-Ag/ZnS) NCs and reported their photocatalytic activity against methylene blue dye. 25 PANI decorated with QDs, provides a large surface for the exchange of electrons and holes and hence an increase in photocatalytic activity. 26 Vishwakarma and his group observed the bactericidal activity of CoFe 2 O 4 /PANI NCs against Gram +ve (S. aureus, B. subtilis) and Gram Àve (E. coli, P. aeruginosa) bacterial strains.…”
