Zn1–xCoxO (x = 0, 0.05, 0.10, and 0.15) nanoparticles (NPs) were synthesized by a coprecipitation method. The crystalline sizes of samples calculated from the powder XRD patterns, which found to decrease with increase cobalt content. FT-IR spectra confirmed Zn–O stretching bands at 468, 456, 452, 461 cm–1 for respective ZnO NPs. SEM images demonstrated distinct flowerlike morphology. photoluminescence all exhibited broad emission in visible range. XPS studies carried out Zn0.90Co0.10O...
Pure ZnO and alkaline metal ion (Mg2+, Ca2+, Sr2+ Ba2+)-doped nanoparticles (NPs) were synthesized by the co-precipitation method. The retained wurtzite hexagonal structure, which was confirmed X-ray diffraction studies. micro-strain properties analyzed through Williamson–Hall analysis. oxidation states of elements (C (1s), O Zn (2p), Mg Ca Sr (3d) Ba (3d)) XPS HRSEM studies showed a reduction in thickness nanoflakes from 63 to 47 nm after doping. EDAX determined amount dopant (alkaline...
The great demand for renewable energy has greatly contributed to the development of solar cell industry. Recently, silicon cells have dominated world market. ease processing gives perovskite (PSCs) an advantage over conventional cells. Regular photovoltaics require expensive, multi-step processes accomplished in a specialized ultraclean-chamber facility at elevated temperature (>1000 °C) and highly vacuumed workspace. Hence, researchers industry focused on PSC as rival Despite this, highest...
So far, numerous metal oxides and hydroxides have been reported as an electrode material, a critical component in supercapacitors that determines the operation window of capacitor. Among them, nickel cobalt-based materials are studied extensively due to their high capacitance nature. However, pure phase does not show significant effect on cycle life. The observed XRD results revealed structures obtained Ni(OH)2 Co-Ni(OH)2 hydroxides. congruency peak positions is attributed homogeneity...
The synthesis of nanoparticles has great control over the structural and functional characteristics materials. In this study, CeO2 Ni-CeO2 spherical were prepared using a microwave-assisted method. characterized via thermogravimetry, X-ray diffraction (XRD), Raman, FTIR, scanning electron microscopy (SEM), photoelectron spectroscopy (XPS), vibrating sample magnetometry (VSM) cyclic voltammetry (CV). pure exhibited flake-like morphology, whereas Ni-doped showed morphology with uniform shapes....
The growth in energy devices and the role of supercapacitors are increasingly important today's world. Designing an electrode material for using metals that have high performance, superior structure, eco-friendly, inexpensive highly abundant is essentially required commercialization. In this point view, quaternary chalcogenide Cu2NiSnS4 with fascinating marigold flower like microstructured electrodes synthesized different concentrations citric acid (0, 0.05 M, 0.1 M 0.2 M) by employing...
