In the X-ray diffraction (XRD) patterns (Fig. 1b), the periodical main peaks at 2θ = 10. 35, 13.77, 17.21, 20.66, 24.12, 27.60, and 31.11° of CTAB molecules remains unchanged after...

XRD patterns at small angles of the samples synthesized using CTAB (CTAB-B, CTAB-E and CTAB-B-450) are shown in Fig. 2, with three diffrac- tograms exhibiting similar behavior of the...

2021年6月21日 · X-Ray diffraction (XRD) analysis. The structure of the product was characterized by X-ray diffraction. Figure 1 shows the XRD diffraction patterns of Bt and CTAB-H-Bt. XRD can determine the purity and crystal structure of the sample, and the peak intensity and peak shape of the diffraction pattern reflect the crystallinity of the sample ...

2017年5月1日 · X-ray diffraction (XRD) patterns were obtained at room temperature on a Rigaku D/max2500 diffractometer employing the graphite filtered Cu Kα radiation (λ = 0.1542 nm) with a scanning rate of 8° min −1 in the 2θ ranges from 5° to 55°.

2017年1月25日 · Fig. 3 (a) presents the XRD profile of the Cu-10 g/l ZrO 2 composite coating developed with different amount of CTAB addition. XRD profiles ( Fig. 3 a) confirm only pure copper peaks with face centered cubic crystal structure, which was …

2020年10月15日 · Herein, we successfully synthesized composite two-dimensional layered structure (Ti 3 C 2 @CTAB-Se) through HF etching, CTAB expansion and subsequent selenium treatment. Through electrochemical and XPS analysis of Ti 3 C 2 @CTAB-Se, it is known that Ti 2+ /Ti 4+ and Se 0 /Se x+ undergo a reversible redox reaction during charging/discharging.

The ferrite samples were characterized by X-ray powder diffraction (XRD), scanning electron microscopy (SEM), and Fourier transform infrared spectroscopy (FTIR).

CTAB and SDS modifications of Na-MMT to achieve greater basal spacing. The effect of modification was studied using XRD, FTIR, particle size analysis with zeta-potential and TGA. The modification would help achieving compatibility with polymers through the incorporation of cation and anion into the clay’s interlayer spaces. 2 Experimental

2018年3月14日 · X-ray diffraction (XRD) analysis of the CTAB capped metal sulfide nanoparticles reveals the formation of hexagonal structure. High-resolution transmission electron microscopy (HRTEM) images show that the morphology of the capped copper sulphide samples consists of hexagonal structure and capped cadmium has spherical shape and also confirms the ...
