CdS–Graphene nanocomposite: synthesis, adsorption kinetics and high photocatalytic performance under visible light irradiation

Sandwich-like octahedral cobalt disulfide/reduced graphene oxide as an efficient Pt-free electrocatalyst for high-performance dye-sensitized solar cells

“…Nevertheless, the graphite (002) diffraction peak is not clearly observed, which may be attributed to the fact that the restacking of the graphene sheets is restrained by immobilizing the CoS 2 nanoparticles onto both sides of graphene sheet, resulting in the weak or even disappearance of the graphite (002) diffraction [43]. In addition, the weak diffraction signals of non-crystalline and low-content RGO may also be covered up by the strong diffraction signals of CoS 2 due to its high crystallinity [44]. Note that the diffraction pattern of the bare CoS 2 sample prepared with the absence of GO can be partly (Fig.…”

Polymer supported graphene–CdS composite catalyst with enhanced photocatalytic hydrogen production from water splitting under visible light

“…Xian and 5 co-workers prepared SrTiO 3 -graphene nanocomposites and suggested that graphene could capture the photogenerated electrons and increased the availability of electrons and holes for photocatalytic reaction [19]. As graphene-based composites exhibit such particular chemical and physical characters, CdS-graphene composite was investigated and showed enhanced activity in dye degradation and hydrogen evolution [23][24][25]. However, in graphene-based nanocomposites, strong π-π interaction always leads to aggregation and stacking between graphene sheets.…”

One-step Synthesis of Pt Nanoparticles Highly Loaded on Graphene Aerogel as Durable Oxygen Reduction Electrocatalyst

“…Fig. 1a shows that the IR spectrum of GO reveals that the characteristic peaks of GO appear at 1726 cm À1 (C-O stretching vibrations of -COOH group), 1620 cm À1 (O-H deformation vibrations of -COOH group), 1045 cm À1 (C-O stretching vibration of epoxy groups), and $3413 cm À1 (O-H stretching vibration, a broad band) [14,15], thereby indicating the presence of a large amount of oxygencontaining groups within GO. Most bands related with the oxygen-containing functional groups vanished in the IR spectrum of the Pt/GA after co-reduction.…”
