Preparation of nanocrystalline praseodymium oxide with different shapes via a simple thermal decomposition route

Abstract

Present report describes the surfactant-free synthesis and characterization of nanocrystalline praseodymium oxide. For this purpose, praseodymium source ([PrL(NO 3 ) 2 ]NO 3 (L = (N,N 0 -bis(2 0 -hydroxyacetophenonimine)-o-dipropylene triamin) was prepared and its thermal decomposition was performed in at various temperatures in the 300-800°C. Results of this investigation demonstrate that praseodymium oxide with very uniform sphere-like shape, small grain size and pure cubic phase could be synthesized by thermal decomposition of the obtained praseodymium source at 600°C. FESEM, FT-IR, TGA, XRD, TEM, EDX, PL and UV-Vis were applied to study the formation of as-prepared nanoparticles and their structure, shape, elemental composition and optical characteristics. Moreover, the photocatalytic characteristics of as-synthesized praseodymium oxide were examined by photodegradation of b-naphthol under UV light illumination.

Nd2O3 nanostructures: Simple synthesis, characterization and its photocatalytic degradation of methylene blue

“……Rare earth metal oxides, particularly neodymium oxide (Nd 2 O 3 ), have recently attracted enormous interest for application in catalysts, UV absorbent, luminescent materials, protective coatings and © 2017. This manuscript version is made available under the Elsevier user license http://www.elsevier.com/open-access/userlicense/1.0/ 2 magnets owing to their wonderful properties [1][2][3][4][5][6][7][8]. There are a variety of ways to synthesize Nd 2 O 3 , including sol-gel, hydrogen plasma-metal reaction, precipitation, thermal decomposition and combustion [9][10][11][12][13][14].…”

Preparation, characterization and photocatalytic properties of Ag2ZnI4/AgI nanocomposites via a new simple hydrothermal approach

“……There has been increasing interest in the preparation of nanostructures in recent years owing to their considerable features as well as excellent usages in different fields [1][2][3][4][5]. To date, several technologies including precipitation, salt-assisted combustion, ultrasound irradiation, solid-state reaction, thermal decomposition and hydrothermal way have been explored to produce nanostructures [6][7][8][9][10][11][12][13][14] prepared several sorts of nanosized structures and studied their effects on the various usages [15][16][17][18][19]. Herein, we prepared silver zinc tetraiodide/silver iodide (Ag 2 ZnI 4 /AgI) nanocomposites and evaluated their photocatalytic behavior.…”
