Nd2O3-SiO2 nanocomposites: A simple sonochemical preparation, characterization and photocatalytic activity

Abstract

NdO-SiO nanocomposites with enhanced photocatalytic activity have been obtained through simple and rapid sonochemical route in presence of putrescine as a new basic agent, for the first time. The influence of the mole ratio of Si:Nd, basic agent and ultrasonic power have been optimized to obtain the best NdO-SiO nanocomposites on shape, size and photocatalytic activity. The produced NdO-SiO nanocomposites have been characterized utilizing XRD, EDX, TEM, FT-IR, DRS and FESEM. Application of the as-formed NdO-SiO nano and bulk structures as photocatalyst with photodegradation of methyl violet contaminant under ultraviolet illumination was compared. Results demonstrated that SiO has remarkable effect on catalytic performance of NdO photocatalyst for decomposition. By introducing of SiO to NdO, decomposition efficiency of NdO toward methyl violet contaminant under ultraviolet illumination was increased.

Ultrasonically and Photonically Simulatable Bi‐Ceria Nanocubes for Enhanced Catalytic Degradation of Aqueous Dyes: A Detailed Study on Optimization, Mechanism and Stability

“…The sonocatalytic degradation mechanism was predominantly based on both light and heat energy generated by the cavitation effect during ultrasonic irradiation. The wide wavelength range of photons was generated by the sonoluminescence due to the cavitation effect ,. The generated photons with a suitable wavelength will excite the 5BCO nanocubes and consequently performs the degradation reaction with organic dyes.…”

A simple hydrothermal route for the preparation of novel Na–Y–W nano-oxides and their application in dye degradation

“…[29][30][31] Among all the methods, the hydrothermal method has gained growing attention due to a range of advantages including broad area of materials, purity of products, uncomplicated usage, and short reaction time. [32][33][34] In the study, sodium yttrium tungstate nanoparticles were fabricated by a hydrothermal approach, and then various saccharides, such as glucose, fructose, lactose, cellulose, and starch were applied as capping agents. The obtained particles were then heated at specied temperatures to produce highly active NaY(WO 4 ) 2 nanoparticles, which were utilized as photocatalysts.…”
