Abstract
Green approach synthesis to produce metal oxide nanoparticles (MgO NPs) is so important due to unique properties controlled by the synergistic effects of metal and plant-constituents using plant extracts of Chickpea leaves plant have been effectively as a natural and renewable reducing, chelating, stabilizing, natural binding agent, and precipitating agent, it is used in the synthesis of magnesium oxide nanoparticles. The synthesized MgO nanoparticles have a cubic crystal structure with an average crystallite size of (22.08nm) at 800 nm, according to the X-ray diffraction (XRD) pattern. The synthesized MgO nanoparticles have a cubic crystal structure with an average crystallite size of (22.08nm) and, (EDX Spectrum) shows the composition of MgO. FE-SEM characterization revealed the presence of MgO with a spherical shape, and the average particle size was confirmed (31.23 nm). As indicated by the anisotropic patterns of MgO, the obtained (Raman) spectrum of MgO shows a strong peak in different regions indicating the cubic structure. The optical energy gap was calculated using DRS analysis and found to be (4.8eV). Gas sensing tests for H2S and NO2 revealed that these hierarchically porous MgO architectures were highly promising for gas sensor applications. Their unique structures significantly improve gas diffusion in the material.
