Rational Design of Dynamic Bimetallic NiCoSe2/2D Ti3C2Tx MXene Hybrids for a High-Performance Flexible Supercapacitor and Hydrogen Evolution Reaction

“…Meanwhile, the 002 plane evidences the successful embedment of the layered Ti 3 C 2 T x structure, maintaining the peak at 2Θ of nearly ∼9° (marked by the blue dotted box). It is noteworthy that the incorporation of Ti 3 C 2 T x into the pristine matrix also yielded the same crystal structure without changing the obvious original phase; however, intensification of the peak intensities and a slight shift in the (002) plane positioned at 2Θ = 33.55° are observed, attributed to the increase in crystallinity (Figure a). , …”

“…It is noteworthy that the incorporation of Ti 3 C 2 T x into the pristine matrix also yielded the same crystal structure without changing the obvious original phase; however, intensification of the peak intensities and a slight shift in the (002) plane positioned at 2Θ = 33.55°are observed, attributed to the increase in crystallinity (Figure 2a). 56,57 Distinctive diffraction patterns of MAX compared to those of the pristine MXene are noticed and well indexed in Figure 2b. In particular, diffraction planes (002), ( 004), ( 006), ( 008), ( 111), (200), and (110) arise from the peaks at 8.…”

Preparation and Characterization of Polyvinyl Alcohol (PVA)/ZrO2 Composite Membranes

“…[ 42 ] The peaks at 1235 cm −1 , 1081 cm −1, and 1020 cm −1 are corresponding to –CH 2 wagging vibrations, –CH 2 stretching vibration, and C–O stretching of acetyl groups in the PVA backbone, respectively. [ 43 ] The absorption band at 914 cm −1 is assigned to CH 2 rocking vibration and the band at 827 cm −1 corresponds to C–C stretching and also C–H out‐of‐plane vibrations. [ 44–46 ]…”

“…[42] The peaks at 1235 cm À1 , 1081 cm À1, and 1020 cm À1 are corresponding to -CH 2 wagging vibrations, -CH 2 stretching vibration, and C-O stretching of acetyl groups in the PVA backbone, respectively. [43] The absorption band at 914 cm À1 is assigned to CH 2 rocking vibration and the band at 827 cm À1 corresponds to C-C stretching and also C-H out-of-plane vibrations. [44][45][46] In the FTIR spectra of PVA/ZrO 2 (13 wt%) (Figure 5b) composite membrane, the observed FTIR peaks are similar to the PVA peaks except two new peaks are observed at 963 and 695 cm À1 are categorized as the zirconium and oxygen (Zr-O) band stretching mode, [32,47] which indicates the presence of ZrO 2 nanoparticles in the composite membrane.…”
