Ternary alkali metal chalcogenide engineered reduced graphene oxide (rGO) as a new class of composite (NaFeS2-rGO) and its electrochemical performance

Green Synthesis of Ni-Cu-Zn Based Nanosized Metal Oxides for Photocatalytic and Sensor Applications

“…According to the data shown in Figure 12, there is a significant difference between the anodic and cathodic peak intensities, confirming that the synthesized metal oxides are appropriate for use in sensing applications. A peak at −0.2 V corresponds to the anodic oxidation peak, and a peak at −0.5 V corresponds to the cathodic reduction peak [29], as can be observed in Figure 12. As the concentration of the sensing analyte increases, there is no significant shift in the peak, and both the oxidation and reduction peaks are clearly visible, indicating that CuO is suitable for use as a glucose sensor [29][30][31].…”

NiO exhibits a significant shift in both the oxidation and reduction peaks, with the oxidation peak shifting completely to the negative potential (−0.5 V) and the reduction peak shifting completely to the positive potential (−0.43 V) [32,33].…”

Elucidating an efficient super-capacitive response of a Sr2Ni2O5/rGO composite as an electrode material in supercapacitors

“…It was observed that for x = 0.00 composition, the intensity peaks were identied corresponding to the (141), ( 051), ( 042), ( 161), ( 202), ( 260), (143), and (341) crystal planes, which were determined using an analytical approach as described by B. D. Cullity. 21 The diffraction analysis conrmed the orthorhombic crystal structure of the sample with x = 0.00, as all the peaks were matched well, with the reference ICSD # 00-034-1475, having Fd 3m space group symmetry, which is a characteristic reference pattern of Sr 2 Co 2 O 5 . The existence of contaminationfree diversion peaks and the maximum intensity peak seemed around 32.40°denoting to (141) plane accrediting to the progress of the highly crystalline nature.…”
