Hydrothermal Crystallization of Bismuth Oxychlorides (BiOCl) Using Different Shape Control Reagents.

ABSTRACT: Bismuth oxychloride photocatalysts were obtained using solvothermal synthesis and different additives (CTAB-cetyltrimethylammonium bromide, CTAC-cetyltrimethylammonium chloride, PVP-polyvinylpyrrolidone, SDS-sodium dodecylsulphate, U-urea and TU-thiourea). The effect of the previously mentioned compounds was analyzed applying structural (primary crystallite size, crystal phase composition, etc.), morphological (particle geometry), optical (band gap energy) parameters, surface related properties (surface atoms' oxidation states), and the resulted photocatalytic activity. A strong dependency was found between the surface tension of the synthesis solutions and the overall morpho-structural parameters. The main finding was that the characteristics of the semiconductors can be tuned by modifyin
