The data of article "Annealing crystallization control mechanism of catalytic degradation properties of Fe-based amorphous ribbons"

This paper clarifies the conditions of whether the catalytic degradation performance of iron-based industrial amorphous strips decreases or increases after annealing and crystallization, which provides a useful reference for the regulation of degradation performance. The formation of α-Fe phase in the alloy after low-temperature annealing disrupts the substable structure of the amorphous strip, which is the main reason for the significant decrease in the catalytic degradation performance; whereas, the primary cell effect between the crystallized phase and the metal compounds as well as the replacement reaction between the enriched Cu clusters and the zero-valent iron in the alloy after high-temperature annealing at 650 ℃ or above greatly improves the catalytic degradation rate of the alloy. This dataset includes the data from Figures 1 to 6 and Tables 1 and 2 in the article "Annealing crystallization control mechanism of catalytic degradation properties of Fe-based amorphous ribbons", including microstructural characterization, surface morphology characterization, and catalytic degradation properties of the materials. Figure 1 shows the (a) XRD and (b) DSC spectra of Fe-Si-B-Cu-Nb industrial amorphous ribbons; Figure 2 shows the XRD spectra of Fe-Si-B-Cu-Nb industrial ribbons after annealing at different temperatures, which is a microstructural characterization; Figure 3 shows the UV spectra of industrial amorphous ribbons and its degradation of Acid Orange 7 after annealing at different temperatures for 20 min; Figure 4 shows the UV spectrum of Fe-Si-B-Cu-Nb industrial amorphous ribbons and its degradation of Acid Orange 7 after annealing at different temperatures. B-Cu-Nb industrial amorphous ribbons and its degradation of Acid Orange 7 after annealing at different temperatures: (a) Ct/C0 normalized curve, (b) dye decolorization rate, (c) -In function, and (d) histograms of reaction rate constants, which describes the catalytic degradation of the amorphous ribbons and the ribbons after annealing at different temperatures; Figure 5 shows the surface SEM images of the ribbons after degrading Acid Orange 7 at different temperatures, and Figure 6 shows the surface morphology of the ribbons after annealing at 700 ℃ for 20 min with (a) SEM images and the corresponding (b) Cu, (c) O, (d) C, (e) Fe, and (f) Si elemental distribution images, which describes the surface morphology of the ribbons. Table 1 shows a comparison of typical amorphous alloys used for the catalytic degradation of azo dyes, comparing the catalytic degradation performances of several zero-valent metal bases for comparison; Table 2 shows the calculation results of α-Fe grain size at different annealing temperatures. In addition, Figures 1—4 show the opuj files plotted using the 2021 version of origin.
