Reduction degree of reduced graphene oxide (RGO) dependence of photocatalytic hydrogen evolution performance over RGO/ZnIn2S4 nanocomposites

Chromium-modified Bi 4 Ti 3 O 12 photocatalyst: Application for hydrogen evolution and pollutant degradation

“…The electron-transfer resistance (R ct ), whose value is acquired by measuring the semicircle's diameter, reflects the effectiveness of charge transfer occurring in the system. In summary, the smaller R ct value is, the more effective the charge transfer within the system is [59,60]. Table 2 The above SEM and TEM results confirm that addition of an optimal Cr content to Bi 4 Ti 3 O 12 effectively not only causes diminished particle size but also maintains uniform distribution of thinned nanosheets.…”

Designing rGO/MoS2 hybrid nanostructures for photocatalytic applications

“…ammonium tetratiomolybdate, 32 or with a mix of ammonium eptamolybdenate or sodium molybdate dihydrate 33 and thiourea, 34 thus obtaining a nanocomposite, which can be suitable as counter-electrode in dye-sensitized solar cells. 42,43 The structural and morphological compatibility between graphene-like materials and single-layer MoS 2 sheets should enable better intercalation to achieve the anticipated benefits of such integration. 35 On the other hand, the top-down approach, consisting in breaking up the massive and bulk MoS 2 material, allows to obtain particles of decreased dimensions.…”

Facile synthesis of Ag/AgBr/RGO nanocomposite as a highly efficient sunlight plasmonic photocatalyst

“…The XPS spectra of the Ag/AgBr/RGO nanocomposite in the C 1s region show peaks at 284.8 and 288.6 eV, which can be assigned to the sp 2 -hybridized carbon (C\C) and carboxyl (O\C_O) respectively (Fig. 4c) [17,18]. As compared to unreduced GO, the intensity of the peak ascribed to the carboxyl (O\C_O) (288.5 eV) in Ag/AgBr/RGO decreases, while the peak ascribed to the epoxy/hydroxyls carbon (C\O) (287.1 eV) totally disappears, indicating the reduction of GO to RGO via the glycothermal treatment (Fig.…”
