Synergistic photocatalytic dye mitigation and bacterial disinfection using carbon quantum dots decorated dual Z-scheme Manganese Indium Sulfide/Cuprous Oxide/Silver oxide heterojunction

Prevalence of multidrug-resistant strains in device associated nosocomial infection and their in vitro killing by nanocomposites

“…We tested the antibacterial activity of carbon quantum dots decorated dual Z-scheme Manganese Indium Sulphide/Cuprous Oxide/Silver oxide Nanocomposites using the agar well diffusion assay and by enumerating the CFUs as described earlier. Different concentration of nanocomposite (1.25 mg/ml, 2.5 mg/ml & 5 mg/ml) was used [ [16] , [17] , [18] ].…”

Understanding the Principles and Applications of Dual Z-Scheme Heterojunctions: How Far Can We Go?

“…28 The comparison of different operation performance of dissimilar heterojunctions made under different conditions is not necessarily conclusive, but the general performance of S-scheme composites (both S-scheme and dual S-scheme) does not surpass that of Z-scheme and dual Zscheme heterostructures as reported in the literature albeit under different conditions. 32 The S-scheme heterojunction accomplishes improved photocatalytic performance indexed to efficient charge separation and robust photoredox ability. 25,33 The conduction energy band bending, the electron depletion layer, and the interfacial built-in electric field are the archetypal characteristics of the S-scheme and dual S-scheme systems, which are the driving forces for the formation of the electron transport path of the S-scheme and differentiate it from the Zscheme.…”

Designing inorganic–magnetic–organic nanohybrids for producing effective photocatalysts for the purification of water

“…According to the basic principle of heterogeneous photocatalysis, the electronic structure of a semiconductor has a strong effect on the performance of photocatalytic degradation of pollutants. 10,11 Depending on the band gap ( E g ) of the semiconductor, the electrons, which exist in the valence band (VB) of the photocatalyst, are excited and transferred to the empty conduction band (CB) by absorbing light to create electron–hole pairs. However, they start to recombine within a few nanoseconds if the photogenerated charge carriers are not utilized in photocatalytic reactions.…”

“…In addition, the poor selective adsorption and high concentration of organic pollutants in industrial waste water causes the poisoning of photocatalysts and decreases their activity in the water treatment process. 10,11…”
