“…[28b] Moreover, the value of lattice parameters a of hydrotalcites, which represents the distance between two adjacent metal ions on the laminate, determines the degree of lattice distortion. [31] The bigger a is, the more severe distortion in hydrotalcites. The structural evolution of the hydrotalcites was monitored by calculating a derived from the (110) lattice plane.…”

“…For LiMoFeCoNi HEH, the increase of a is quite large (Δa = 0.045 nm) compared with NiCo LEH, which is far more than previously reported CuZnAl hydrotalcite of Δa values (0.012 nm). [31] The increased lattice parameter a in LiMo-FeCoNi HEH is because a is very sensitive to different metal ions. [28a] The introduction of high valence metal ions (Cr 3+ , Mo 5+ , W 6+ ) in HEHs increases the electrostatic repulsion and result in the lattice expansion, indicating severe lattice distortion in HEHs.…”

“…Therefore, the H and CuH-n materials preserved the hydrotalcite structure. However, the peak height of the characteristic peaks of hydrotalcite structure at the planes of (003), (009) and (110) decreased with the increasing proportion of Cu 2+ in the material [2,7]. Based on the distance values (d) between the layers of the hydrotalcites at the plane of (003) and (110), the a and c parameters were obtained, where the a parameter represents the cation-cation distance in the brucite layer and a = 2.d 110 .…”

“…The XRD analysis results show that the Zn 2+ /Al 3+ molar ratios of approximately 2:1 and 1.5:1 were the most suitable for the structure of LDHs [1] and CuZnAl material [2]. The ZnAl materials were used as the modification substrate by various agents (e.g., Cu, Ti and Eu), as well as organic composes (e.g., EDTA and EDDS) [6,7]. Therefore, promising results of catalytic and adsorbent materials were obtained in environmental treatments.…”
