Abstract:
... In this work, the first-ever reported nanocomposite electrode of nitrogen-doped graphene–titanium oxynitride (NG–TiOₓNy) for capacitive deionization (CDI) was synthesized via hydrothermal reaction and a high-temperature nitridation process. The physiochemical characterizations revealed that the nitrogen was doped in the graphene structure mainly in the form of graphitic nitrogen and the TiOₓNy was ...

These nanoparticles (NPs) are often dispersed and stabilized in the solution by some surfactants during the unconventional oil ores processing. Herein, the PEG600–KH560 (PK) has been grafted onto Fe₃O₄ NP surfaces, obtaining a kind of hydrophilically-modified recyclable nanopa ...

Abstract:
... Graphene oxide (GO) has been the focus of attention as it can enhance the photocatalytic activity of semiconductors due to its large specific surface area and remarkable optical and electronic properties. However, the enhancing effect is not ideal because of its easy self-agglomeration and low electronic conductivity. To improve the enhancing effect of GO for ZnO, three-dimensional GO/MoS₂ composi ...

Their performance as photocatalysts was systematically evaluated during RhB degradation under visible light irradiation. The composite with 7 wt% g-C₃N₄ was found to be 7 times more efficient as a photocatalyst than pri ...

Abstract:
... Graphene oxide sheets (GOSs) are introduced between indium tin oxide (ITO) and CH₃NH₃PbI₃ in inverted hole-transport layer-free planar heterojunction perovskite solar cells. The concentration of the GOSs is extremely low and they are sporadically covered on the ITO substrates. Combined with the high resistance of these GOSs, they cannot be regarded as an interface layer. However, the GOSs can act ...
