“…In this investigation, the enhanced photocatalytic activity can be related to appropriate distribution of the pore in the nanocrystalline ZnMoO 4 surface, high hydroxyl amount and high separation rate of charge carriers (Fig. 6c) [27].…”

Zinc molybdate rod-like nanostructures have been successfully synthesized by precipitation method process in the presence of different surfactants. This study aimed to investigate the effects of different surfactant such as sodium dodecyl sulfate, polyethylene glycol, and cetyltrimethylammonium bromide and solvent on the morphology and particle size of final products. It was found that the size and morphology of the products could be greatly influenced by the aforementioned parameters. To the best of authors' knowledge, this is the first report on the synthesis of ZnMoO 4 nanostructure with different morphologies in the presence of ethanol as a solvent. The assynthesized products were characterized by XRD, SEM, UV-Vis, and EDS techniques. To evaluate the photocatalyst properties of nanocrystalline zinc molybdate, the photocatalytic degradation of methyl orange under visible light irradiation was carried out.

Highly photocatalytically active anatase TiO 2 were synthesized by a solvothermal method using tetrabutyl titanate (TBT), citric acid, and ethanol as row material. The morphology and photocatalytic activity of titanium oxide have changed significantly with the presence of surfactants, such as cetyltrimethylammonium bromide (CTAB), sodium dodecylbenzenesulfonate (SDBS), and diethanolamine (DEA). Scanning electron microscope and X-ray powder diffraction results show that the synthesized products are anatase TiO 2 spherical particles with a micronanostructure. The crystal type of TiO 2 has no obvious change with the addition of different surfactants, but the morphology, size, and dispersion of the TiO 2 particles have changed to some extent. Among the three surfactants, CTAB is beneficial to reduce TiO 2 particle size and improve TiO 2 dispersion and agglomeration. DEA is favor to self-assembly the nanocrystals into spherical particles. Degradation of methyl orange photocatalyzed by TiO 2 prepared with CTAB as surfactant reaches 95.4% under ultraviolet light for 100 min. After five recycles, the catalyst did not exhibit significant loss of photocatalytic activity, confirming that the photocatalyst is essentially stable. This work indicates that the surfactant-assisted solvothermal method is an effective approach to improve the structure, morphology, and photocatalytic performance of TiO 2 . Moreover, the surfactants with various types can interact with the precursors of TiO 2 in different ways.

“…It is generally accepted that photocatalytic activity depends mainly on the diffusion of reactants and products, and therefore the favorable distribution of the pore. It seems that the very well photocatalytic activity of the as-prepared nanocrystalline barium stannate can be due to the favorable distribution of the pore, high hydroxyl amount and high separation rate of the charge carriers [27,[31][32][33][34][35][36] (Fig. 9b).…”

Pure cubic nanocrystalline barium stannate was synthesized by new simple coprecipitation strategies that employed tin (II) chloride and [bis(salicylaldehydato) barium (II)] as tin and barium sources in presence of tetramethylethylenediamine (TMED) as a novel precipitating agent. This work is the first successful attempt for the preparation of nanostructured barium stannate by utilizing TMED via a facile coprecipitation way in presence of tin (II) chloride and [bis(salicylaldehydato) barium (II)]. The structural, optical and morphological characteristics of the as-prepared nanostructured barium stannate were studied by UV-vis diffuse reflectance spectroscopy, transmission electron microscopy, X-ray diffraction, scanning electron microscopy (SEM), Fourier transform infrared spectroscopy and energy dispersive X-ray microanalysis (EDX). According to the SEM results, it was found that shape and size of the barium stannate can be dramatically controlled by setting critical preparation factors such as the barium source, precipitating agent type, reaction pH, surfactant type and dosage of surfactant. The photocatalytic characteristics of as-obtained nanocrystalline barium stannate were also examined by degradation of erythrosine dye as water contaminant.
