Effects of various morphologies on the optical and electrical properties of boehmite nanostructures

Abstract

This work reports the variations in the fluorescence and ultra-high dielectric properties of various boehmite nano-structures.

InSitu-Grown Cdot-Wrapped Boehmite Nanoparticles for Cr(VI) Sensing in Wastewater and a Theoretical Probe for Chromium-Induced Carcinogen Detection

“…46 The symmetric and asymmetric bands found at 1071 and 1154 cm −1 , respectively, are characteristic Al−O−H vibrations. 44 There are small bands located at 1223, 1336, and 1746 cm −1 , which are due to the C−O−C stretching and CO vibrations confirming the presence of cdots in the sample. 47,48 A vibrational maximum seen at 1526 cm −1 is assigned to the N−H vibration ascribed to the formation of nitrogenous cdots.…”

“…The FTIR spectrum in Figure 2 depicts the presence of AlO 6 radicals in the sample as the vibrations occur in the range from 590 to 780 cm −1 . 44 The −OH deformation linked to aluminum ions has also been observed (896 cm −1 ). These bands below 1000 cm −1 ascertain the formation of boehmite.…”

“…A similar phenomenon has been reported in our previous work where ethylenediamine results in spherical morphology of boehmite nanoparticles when added to aluminum nitrate salt. 44 The 44 This extra proton (H + ) chelates with ethylenediamine, which increases the pH to a higher value (12, in this case) and starts precipitation due to Ostwald ripening.…”

“…Information regarding structural details and bonding networks could also be analyzed using this characterization technique. 44 The X-ray diffractogram of the material was examined using a D8, Bruker AXS diffractometer, Wisconsin, USA, equipped with a Cu Kα target of 1.5418 Å and operated at a 35 kV, 35 mA bias with a scan speed of 2 s/step. The diffractogram of the sample was further analyzed using the standard Rietveld refinement method superposing the experimental data with the COD file no.…”

A review of current knowledge and future trends in polymer/boehmite nanocomposites

“…The Young's modulus was observed as 138-156 GPa. Roy et al 23 deliberated the optical and electrical characteristics of boehmite. The nanoparticles developed have unique needle-, flower-, and spherical-like shapes.…”
