Observation of synergistic effects in multiphase tungsten oxide (WO3) nanocomposite and its role in enhanced supercapacitive and photoluminescence properties

Controlled Growth of a Highly Energetic, Less Electron-Dense Tetrahedral Fe3+ Phase on the Surface of α-Fe2O3 Nanoparticles toward Enhanced Optical, Magnetic, and Supercapacitive Performance

“…Because the Nyquist plot is so vulnerable to variations and is useful for pondering probable reaction mechanisms, we have further explored the reaction kinetics of the materials using the EIS spectroscopic analysis (shown in Figure ). EIS spectra of all samples in 2 M Na 2 SO 3 electrolytes (Figure a) depict a definite semicircular arc and a linear portion transforming into a second semicircular arc with the alteration of samples A 1 to A 4 . This pattern is consistent with the modified Randles circuital model (shown in Figure d).…”

Glutathione-Mediated Synthesis of WO3 Nanostructures with Controllable Morphology/Phase for Energy Storage, Photoconductivity, and Photocatalytic Applications

“…Moreover, the core level N 1s spectrum (Figure c) can be deconvoluted into two peaks at 399.10 and 400.64 eV corresponding to NH and NH 3 + , respectively. Deconvolution of the C 1s core level spectrum (Figure d) revealed four peaks at 284.28 eV (C–C, C–H), 285.1 eV, 286.52 eV (C–N and N–CO from GSH), and 288.42 eV (GSH O–CO group). , …”

“…Deconvolution of the C 1s core level spectrum (Figure 3d) revealed four peaks at 284.28 eV (C−C, C−H), 285.1 eV, 286.52 eV (C−N and N−C�O from GSH), and 288.42 eV (GSH O−C�O group). 39,40 The porosity and specific surface areas of the as-synthesized samples were estimated via the Brunauer−Emmett−Teller (BET) method by N 2 -physisorption analysis at 77 K. Figure 4a−c displays dinitrogen (N 2 ) adsorption−desorption isotherms for samples GHTO, GTO, and HTO, and Figure S2 depicts the corresponding pore size distributions.…”
