ANALYSIS OF STRUCTURE AND ANTIMICROBIAL ACTIVITY OF CeO2 AND Nd2O3 NANOPARTICLES

Abstract

Cerium oxide (CeO2) and Neodymium oxide (Nd2O3) nanoparticles using local content have been synthesized by precipitation method. The CeO2 and Nd2O3 nanoparticles were characterized by X-Ray Diffraction (XRD) and Fourier Transform Infrared (FTIR) to analyze the material phase and structure. The XRD spectrum shows that CeO2 and Nd2O3 nanoparticles have face-centered cubic and hexagonal, and cubic, respectively. The anti-microbial activity of CeO2 and Nd2O3 nanoparticles was analyzed by diffusion method using gram-negative bacteria (E.coli, S.aeureus, P. aeruginosa), and gram-positive bacteria (S. entericatyphi, L. monocyogenes), and fungus (C. albicans). The result confirms that CeO2 and Nd2O3 nanoparticles have the capability of patogen microbia inhibition. The CeO2 nanoparticles have the effective activities of inhibition for the microbia of S. aereus and S. entericatyphi, whereas Nd2O3 nanoparticles can inhibit the microbia of P. aeruginosa, S. entericatyphi, and L. monocyogenes.

The La+3-, Nd+3-, Bi+3-Doped Ceria as Mixed Conductor Materials for Conventional and Single-Component Solid Oxide Fuel Cells

“…For La2Ce2O7, the absorption peak in the fingerprint region found at 678 cm −1 may be caused by La-O stretching. The peaks at 411 [40] and 533 cm −1 [41] correspond to the characteristic Nd-O vibrations of Nd2O3 particles. The Na2Ce2O7 band in the fingerprint region was found at 584 cm −1 , near the literature value.…”

Neodymium oxide nanoparticles synthesis using phytochemicals of leaf extracts of different plants as reducing and capping agents: Growth mechanism, optical, structural and catalytic properties

“…[24] Neodymium is one of the rare metals, which is used as a catalyst for the various process such as CO 2 harvesting, [25] cancer treatment, [26] luminescent materials, [27] lasers, [28] ceramic coloring, [29] enhancing optical properties of glass, [30] gas sensors, [31] coatings, [32] and anti-bacterial agents. [33] These can be synthesized using various methods such as hydrothermal, [34] sol-gel, [35] microemulsion, [36] coprecipitation, [37] atomic layer deposition, [38] combustion methods [39] and green synthesis. [40][41][42] The particle size of Nd 2 O 3 nanoparticles prepared using sol-gel method was around 30 nm.…”
