Development of a new synthetic strategy for highly reduced graphene oxide-CdS quantum-dot nanocomposites and their photocatalytic activity

Dielectric and Conductivity Relaxation of rGO@CdS Nanocomposites via In Situ Assembly of CdS Nanoparticles on an rGO Layer

“…Pure GO and CdS are used for comparison. As for the as-prepared GO sample, two typical diffraction peaks at 13 and 42 o can be indexed to (001) and 100g planes, matching well with those of the reported GO structure. − These two peaks are intrinsic to the GO sheets to which the (001) and 100g diffraction peaks are related to the spacing between adjacent carbon layers and the hexagonal ring structure within each GO sheet . The XRD pattern of the pure CdS sample (without GO) shows nine diffraction peaks.…”

“…25−27 These two peaks are intrinsic to the GO sheets to which the (001) and 100g diffraction peaks are related to the spacing between adjacent carbon layers and the hexagonal ring structure within each GO sheet. 25 The XRD pattern of the pure CdS sample (without GO) shows nine diffraction peaks. The diffraction peaks located at 25, 26.7, 28.2, 36.9, 44, and 52 o belong to the hexagonal structure of CdS according to JCPDS card No.…”

“…GO was obtained by oxidation of graphite powder through the modified Hummers method. A typical process was reported in our previous paper . The CdS nanoparticles were fabricated in situ on the GO layer via a low-cost and straightforward CBD method, where the GO nanosheet layer plays a role of “substrate.” Initially, 5, 20, 60, and 100 mg of GO was separately dissolved and exfoliated in 100 mL of DI water for ultrasonic 60 min to obtain a uniformly dispersed solution.…”
