“…Previous research has established that BaMoO 4 particles are synthesized by various fabrication methods such as co-precipitation, hydrothermal, solvothermal, and solid-state. [6][7][8][9][10][11][12][13][14][15][16][17][18][19][20][21][22][23][24] It is understood from these studies that the morphological and crystallinity properties of materials are significantly affected by the synthesis methods, precursor materials, surfactants, and solvents used in the production of nanomaterials. This means that nanoparticles with different properties can be fabricated by changing these synthesis parameters.…”

Barium molybdate (BaMoO4) is one of the materials used extensively in electronic and optical devices. Although there are many synthesis methods in the literature, a route for facile synthesis of nano‐BaMoO4 has been ignored. In this study, BaMoO4 nanoparticles were produced by the co‐precipitation method at room temperature within a short time. The effects of ammonia solutions and surfactants on the morphology of the particles were investigated. Various properties of these materials were characterized by XRD, SEM‐EDX, elemental mapping, TEM, and UV‐Vis analysis methods. Also, the crystal structure parameters and the compatibility of these values with the theoretical calculations were determined by Rietveld refinement. From the HR‐TEM image, the interplanar spacing was calculated as 3.2 Å. It was determined from these analyses that BaMoO4 particles with optical band gaps varying between 3.80 and 3.95 eV were produced in nano and micrometer sizes. It has been demonstrated by this study that the pH of the synthesis solution and the type of surfactant have significant effects on the morphological and optical properties of the materials.

“…The BaMoO 4 presents a scheelite structure with 𝐼41/𝑎 space group formed by distorted [BaO 8 ] and [MoO 4 ] clusters. This material has a high band gap energy (Egap) ~4.2 eV (Pereira et al, 2021;Sczancoski et al, 2010;Xia and Chen, 2010). Due to its poor use of light (ultravisible [UV] light) from the solar spectrum, the photocatalytic efficiency becomes very low.…”

Surfactant effects in the morphology and the photocatalytic activity of the BaMoO4 crystals

et al. 2022

This paper discloses the effect of the surfactant sodium dodecyl sulfate (SDS) in the morphology and the photocatalytic activity of BaMoO4 crystals. Experimental techniques were applied to study the order-disorder degree of the samples. First-principles calculations were performed at density functional theory level with the B3LYP hybrid functional. The morphologies were investigated by field emission scanning electron microscopy, and the theoretical crystal shapes were obtained through the Wulff construction. The photocatalytic activity efficiency of the BaMoO4 crystals was tested against the Rhodamine B (RhB) dye. In this paper, BaMoO4 synthesized with SDS by the coprecipitation method presented a monophasic crystal with a disordered structure. In addition, the presence of this surfactant generated pores on the surfaces of the material, and those pores were responsible for the appearance of the adsorptive ability enhancing the adsorption process of the RhB dye in the dark, in absence of ultraviolet light.
