A prominent peak at 378nm by UV absorption ensured the synthesis of ZnO nanoparticles. The crystalline property revealed that synthesized ZnO nanoparticle is highly crystalline having wurtzite structure. A significant band at~498 to 557cm 1 in FTIR was assigned to the characteristic stretching mode ...
Functional group have been ascertain by FTIR peak assignment. Small variation in structural parameter and ZnO stretching mode indicate substitution of Cu at ZnO site of ZnO nanostructure. The band gap engineering with variable Cu concentration successfully reduces the apparent band gap, which help to ...
Effect of PVA content in ZnO samples calcined at 400 °C and calcination temperatures in 5PVA/ZnO samples on crystallite size (of peak 2θ = 36.1°). Full size image Microscopic studies SEM analysis Figure 4 shows SEM images of ZnO and ZnO/PVA catalysts with various content of PVA 5...
54, the band gap narrowing has been observed in the Ga doped ZnO thin film with increasing concentration of Ga. Hence, the existence of GO concentration in GOZ-7 and GOZ-10 nanocomposite enhance the peak intensity of the emission spectra which confirm the increasing amount of defects and Vo ...
The characteristic peak at 370 nm in the UV–Vis spectra of green-synthesized ZnO NPs was indicated in Fig. 2a. Furthermore, the XRD analysis findings are shown in Fig. 2b, where the ZnO NPs made using the aqueous extract of A. platensis exhibit Bragg reflections at 2θ values of 32.6...
In the present work, nano-molar detection of the analyte was achieved with the help of developed sensor. At modified sensor, there was an elevation in the peak current of the analyte, which was twice the peak current at bare CPE due to the semiconducting properties nanoparticles (Shanbhag et...
Fig. 2 shows the FTIR spectra of pure PANI and the P5CZO20 nanocomposite. The characteristic peaks of emeraldine salt form of PANI observed at 1554 and 1460 cm−1 are attributes of CN and CC stretching vibrations of quinoid and benzenoid units, respectively [42]. Peak observed at 1282 cm...
ZnO nanowires and nanowhiskers were prepared via a novel approach in the presence of surfactant. Several techniques confirmed that the nanostructures are single crystalline with the growth direction along the [1 0 1] axis. Fourier transform infrared spectroscopy also showed that typical peak of ZnO ...
The CuZn alloy formation depends on the ZnO loading of ZnO/Cu-NCs catalysts. H2-TPR profiles of various ZnO/Cu-NCs catalysts (Supplementary Figs.39and40) show that the appearance of reduction peak for supported large ZnO particles corresponds to the decrease in the percentage of CuZn alloy. ...
° peak in BC@MnO2was assigned to amorphous MnO273,94. Compared to the patterns of BC and BC@ZnO, the XRD pattern of BC@MnO2revealed weaker peaks. These weak peaks were probably caused by the charge of the amorphous MnO2, which had an impact on the XRD patterns of other crystals66. ...
