Polyoxometalate Intercalated M2+/Al (M2+=Ni, Mg) Layered Double Hydroxide for Degradation of Methylene Blue

The synthesis and characterization of MAI (M-Ni, Mg) layered double hydroxide (LDH) and intercalated poly- oxometalate is presented. We have reported the growth of polyoxometalate on NiMg layered double hydroxide for degradation methylene blue (MB). By considering variables such as pH of dye solution, dye concentration, and time as degradation variables, the efficiency of organic dye degradation and degradation parameters of M2+/AI (M-2 Ni, Mg) LDH and both composite LDH-polyoxometalate has been identified. X-Ray Diffraction (XRD), Fourier Transform Infra Red (FTIR), Scanning Electron Microscope (SEM), and Ultra Violet Diffuse Reflectance Spectros- copy (UV-DRS) spectroscopy confirmed the layered double hydroxide structure. XRD and FTIR analysis confirmed the single-phase of the as-made and polyoxometalate intercalated LDH. SEM images show the formation of aggre- gates of small various sizes. The material's photodegradation was assessed through methylene blue (MB) degrada- tion process. The result showed that NiAl-Si has a good degradation capacity for MB as compared to NAI-Pw, MgAl-Si, and MgAI-PW. The result shows that LDH composite presents stability and has good photocatalytic ac- tivities toward the reduction of methylene blue. The FTIR measurement confirming the LDH composite structure reveals the materials used in the fifth regeneration. The activity of MB photodegradation pristine were NiAl (45%), MgAl (43%), NiAl-Pw (78%), NiAl-Si (85%), MgAl-Pw (58%), and MgAl-Si (75%), respectively. The LDH- polyoxometalate composite material's capacity to successfully photodegrade, as measured by the percentage of deg- radation, revealed an increase in photodegradation catalysis and the ability of the LDH to regenerate.<br />Copyright & COPY; 2023 by Authors, Published by BCREC Group.
