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. 2022 artículo científico 0100-4670 https://www.redalyc.org/articulo.oa?id=42973868010 https://www.redalyc.org/journal/429/42973868010/ https://www.redalyc.org/journal/429/42973868010/html/ https://www.redalyc.org/journal/429/42973868010/42973868010.epub https://www.redalyc.org/journal/429/42973868010/movil https://doi.org/10.26850/1678-4618eqj.v47.1SI.2022.p80-89 en http://www.redalyc.org/revista.oa?id=429 Eclética Química application/pdf Universidade Estadual Paulista Júlio de Mesquita Filho Eclética Química (Brasil) Num.1 Vol.47 |
