A graphene oxide /samarium sulfide (GO/Sm2S3) composite thin film: Preparation and electrochemical study

Electron beam deposited (Cu2S‐CdS)GOthin film as active electrode for supercapacitor and enhanced photocatalyst for water remediation

“…A visible carboxyl group absorbance was seen at 1024 cm −1 for both the composites 9 . C–C aromatics vibrations, COO– and C–O carboxyl groups were observed at 1097 and 1093, 1381 and 1384, 1273 and 1259 cm −1 , for Cu‐Cd(S 2 CN[Et] 2 ) n ]) and Cu‐Cd‐GO(S 2 CN[Et] 2 ) n ]), respectively 33,35,36 . Vibrations at 1435 and 2924 cm −1 for Cu‐Cd(S 2 CN[Et] 2 ) n ]) while at 1438 and 2928 cm −1 for Cu‐Cd‐GO(S 2 CN[Et] 2 ) n ]) were representative of the CH 2 functional group on the IR spectra 33,34 .…”

Rare Earth‐Based Nanomaterials for Supercapacitors: Preparation, Structure Engineering and Application

“…Carbon materials, such as AC, CNTs, and graphene, are considered as a hybrid composition to improve other active materials due to their exclusive physical and chemical properties, especially their high conductivity and specific surface area [197,198] . Indeed, the composite of RE and carbon materials is an efficient approach to overcome the shortcomings of RE‐based nanomaterials [33,34,49,50,71,73,74,99,126,127,146,193,199–216] . For instance, compared to Sm 2 O 3 nanoparticles, Dezfuli et al.…”

[33,34,49,50,71,73,74,99,126,127,146,193,[199][200][201][202][203][204][205][206][207][208][209][210][211][212][213][214][215][216] For instance, compared to Sm 2 O 3 nanoparticles, Dezfuli et al found that the ionic/electronic transport resistance of the RGO/Sm 2 O 3 nanocomposite was reduced. [50] For graphene/CeO 2 aerogel (Figure 8), Chen and Xue expounded that the high conductivity of graphene and the synergic effect between graphene and CeO 2 are the key factors that affect the electrochemical…”
