Synthesis and Characterization of 2-Furoylthiourea Modified Layered Double Hydroxide Composites

In this study, Layered Double Hydroxide (LDH) derivative ZnCr-LDH, ZnCr-DS-LDH, and 2‑Furoyl Thiourea (FT) modified novel ZnCr-FT-LDH composites were synthesized. The structures of these composites were elucidated using FTIR, XRD, and solid-state 13C-NMR techniques. Thermal analysis studies were carried out using a combined TG/DTG/DTA system. Particle sizes, morphology and elemental analyzes were determined by SEM/EDX, and pore sizes and volumes were investigated by BET analysis. According to SEM analysis, the average grain sizes of ZnCr-DS-LDH, ZnCr-APTES-LDH, and ZnCr‑FT‑LDH were found to be in the range of 1.1–0.8, 0.8–0.4, and 0.6–0.4 µm, respectively. Furthermore, SEM images revealed that the particle size distribution is uniform and the particles have a lamellar structure. XRD patterns of ZnCr-LDH, ZnCr-DS-LDH, ZnCr-APTES-LDH, and ZnCr-FT-LDH confirmed that LDHs have a hydrotalcite structure (JCPDS: 00-052-0010). The basal space of ZnCr-LDH was calculated as 8.08 Å, that of ZnCr-DS-LDH was 9.59 Å, ZnCr-APTES-LDH was 9.29 Å, and the basal spacing of ZnCr-FT-LDH was calculated to be 8.65 Å based on XRD data.
