Abstract
The fabrication of beta-cyclodextrin with nickel incorporation (Ni-BCD-MOF) for the catalytic reduction of nitroaromatic compounds and dyes has been done using a simple, sustainable, and easy vapor deposition technique. The Ni-BCD-MOF was created using only environmentally safe solvents, promoting sustainable development without adversely affecting the environment. The Fourier transform infrared was utilized for the structural elucidation of prepared Ni-BCD-MOF, and UV-visible spectroscopy divulged a narrow band gap (2.15 eV). The X-ray diffraction pattern depicted the crystallinity of Ni-BCD-MOF. Scanning electron microscopy revealed ingot/brick-type crystal structure with an average particle size of 1.92 mu m. The Ni-BCD-MOF exhibited high thermal stability up to 300 & DEG;C confirmed via thermogravimetric analysis. Furthermore, BET studies of Ni-BCD-MOF revealed a surface area of 21.1 m(2) g(-1), which is comparatively higher than the surface area of MOFs synthesized with BCD. The Ni-BCD-MOF manifested impeccable performance in reducing nitroaromatics compounds and dyes (<= 5 min). Ni-BCD-MOF may be used as a suitable substitute for nanocatalysts to reduce organic contaminants due to its high thermal stability, surface area, and catalytic rate constant for reducing azo dyes and nitroaromatic compounds.
