Facile synthesis of monodisperse porous Cu2O nanospheres on reduced graphene oxide for non-enzymatic amperometric glucose sensing

Solvothermal synthesis of Zinc sulfide decorated Graphene (ZnS/G) nanocomposites for novel Supercapacitor electrodes

“…The characteristic peaks at 1047, 1213, 1634 and 1736 cm -1 corresponds to the C-O-C stretching vibrations, C-OH stretching, C=C stretching mode and C=O stretching vibration of COOH group in GO [27]. As compared to GO, the oxygen functional groups at 1213 and 1736 cm -1 disappeared in the composite, showing the reduction of GO.…”

Studies on formation mechanism of 3D Cu2O nanospheres through self-assembly of 0D nanodots

“…3 and S5 (SI). As seen, Sample 4 (S4) which synthesized in 60 mL [19,29] and XRD analysis ( Fig. S1 (SI)).…”

“…The spectrum of the pure Cu 2 O sample ( Fig. 8(b), curve 1) shows two peaks located at 632 cm À1 and 1629 cm À1 , which are attributed to the Cu-O vibration of the porous Cu 2 O NSs and bending vibrations of the O-H groups from the unavoidable adsorbed water, respectively [6,29]. After the adsorption of MO, some new peaks appeared as Fig.…”

“…Nevertheless, to the best of our knowledge, there were still limited reports on the small Cu 2 O nanocrystals less than 100 nm because of a few considerable challenges [26][27][28][29][30]. Therefore, it is an urgent task to investigate the influences of surfactants, solute concentration or types of the acid ions (CH 3 COO À (Ac À ), NO 3 À ) on the final morphologies of Cu 2 O nanocrystals, of which the formation mechanism should also be revealed.…”

Research Status and Development of Cu2O Thin Film Solar Cells

“…Due to the special properties and structure of Cu2O, it has the optical, electrical and photo electrochemical properties. It has potential applications in solar cells, photo catalysis, gas sensing, superconductor, hydrogen production and electrochromic devices [11][12][13][14] . The theoretical photoelectric conversion efficiency of Cu2O based solar cells can reach 20% [15,16] , but the actual conversion efficiency can only reach about 2% due to the factors such as the preparation conditions of the device [17] .…”
