A series of nitrate-based LDH materials was synthesised by using aluminium (Al3+) as a trivalent cation (M3+) with varying M2+ cations such as magnesium (Mg2+), zinc (Zn2+), and calcium (Ca2+) ions to prepare magnesium�aluminium-layered double hydroxide (MgAl-LDH), zinc�aluminium-layered double hydroxide (ZnAl-LDH), and calcium�aluminium-layered double hydroxide (CaAl-LDH), respectively. MgAl-LDH and ZnAl-LDH were synthesised by the co-precipitation method, whereas CaAl-LDH was prepared by the hydrothermal method. The samples were characterised by powder X-ray diffraction (PXRD), Fourier transform infrared spectra (FTIR), thermogravimetric and differential thermogravimetric analysis (TGA/DTG), field emission scanning electron microscope (FESEM), and accelerated surface area and porosity (ASAP) analysis. The PXRD patterns show that MgAl-LDH (9.8 �) had the greatest interlayer spacing, followed by ZnAl-LDH (8.9 �), and CaAl-LDH (8.7 �). The FTIR spectra clearly confirms the presence of nitrate ions in the LDH structure. Two-step degradation behaviour of the samples was observed in the TGA curve. The LDHs exhibit Type IV isotherms and hexagonal structures were observed on the FESEM images. � 2022 Final 2023-05-29T09:40:46Z 2023-05-29T09:40:46Z 2022 Article 10.1016/j.matpr.2022.05.162 2-s2.0-85130431644 https://www.scopus.com/inward/record.uri?eid=2-s2.0-85130431644&doi=10.1016%2fj.matpr.2022.05.162&partnerID=40&md5=b400154e10ff1e8551d3f939fb5bf122 https://irepository.uniten.edu.my/handle/123456789/27193 66 P10 4015 4019 Elsevier Ltd Scopus |
