Superior photocatalytic and electrochemical activity of novel WS2/PANI nanocomposite for the degradation and detection of pollutants: Antibiotic, heavy metal ions, and dyes

Photoresponsive MoS2 and WS2 microflakes as mobile biocide agents

“…Briefly, under irradiation at a suitable energy, electrons can be promoted from the valence band to the conduction band generating electron–hole pairs. The photogenerated electrons can react with O 2 molecules in water to produce O 2 − radicals, whereas the positively charged holes can react with the solvent, in this case water, to generate OH − radicals as follows: 28,30,31 WS 2 /MoS 2 + hν → e − + h + H 2 O → H + + OH − OH − + h + → ˙OHO 2 + e − → ˙O 2 − → 1 O 2 ˙O 2 − + H + → OH − …”

Binary metallic sulphide‐based nanocomposites with ZnO additives: A dual‐functioning electrode material for energy storage and glucose sensing

“…Subsequently, the experimentation involves a gradual increase in glucose concentration within the solution. Moving on to Ni@Cu/WS 2 43.9 425 Iqbal et al [44] WS 2 -PANI 6.42 399.9 Fatima et al [45] NiCoMn-CH nanoflakes 20.31 748.6 Zhong et al [46] MnO 2 /graphene 16 95 Chang et al [47] CoNbS/PANI 35 2400 Afzal et al [24] rGO-MoS 2 -WS 2 15 373 Lima [16] CoS 4 /WS 2 47.3 512 Shrivastav et al [48] Zn-MOF-rGO 7.1 400 Rani et al [49] KCu 7 S 4 /rGO 75 657 Li et al [50] ZnO@CoNbS Figure 10B, it illustrates the introduction of 1.0 mM of glucose into the system. As the potential applied to the working electrode is adjusted, the current undergoes a gradual ascent, a response attributed to adding glucose.…”

Versatility of group VI layered metal chalcogenide thin films synthesized by solution-based deposition methods

“…84,85 Fatima et al deposited WS 2 /PANI nanocomposite by sequential deposition of WS 2 and PANI by hydrothermal and in situ polymerization techniques, respectively. 86 The resultant nanocomposite has been used for the photocatalytic degradation of methyl orange (MO). It has been observed that WS 2 /PANI effectively degraded 97% of MO in 120 minutes under visible light irradiation.…”
