A Facile Synthetic Method to Obtain Bismuth Oxyiodide Microspheres Highly Functional for the Photocatalytic Processes of Water Depuration

Selective Oxofunctionalization of Cyclohexane and Benzyl Alcohol over BiOI/TiO2 Heterojunction

“…Traditionally, photocatalysis has been employed in wastewater treatment [8], destruction of microorganisms [9], and degradation of toxins [10], dyes [11], surfactants [12], fatty acids [13], antibiotics [14,15] and organic pollutants [16,17]. Due to their high reactivity, photocatalytic systems based on semiconductors are non-specific and have been rarely applied in the selective conversion of organic compounds [18].…”

Synthesis, characterization and photocatalytic activity of BiOX (X = Cl, I, Br) and their composites with carbon nanotubes (CNT)

“…But all of it is governed by the type of method used because different methods result in different structural, morphological and optical properties which ultimately lead to differences in photocatalytic response. As per the previously mentioned reports, the main based morphology for BiOX is 2-D nanosheets [37], although recently other types of morphologies were also reported such as 1-D (nanoparticles or nanobelts) [38,39] or 3-D hierarchical structures (microspheres, microflower-like) [40,41]. The common source for bismuth includes Bi(NO3)3•5H2O, Bi(NO3)3, NaBiO3•2H2O, Bi2O3, Bi, BiCl3, and BiI3 while surfactants like hexadecyl trimethylammoniumchloride (CTAC) and hexadecyltrimethylammoniumbromide (CTAB), halogen acids HX (X = Cl, Br, or I), NaX (X= Cl, Br, or I), KX (X= Cl, Br, or I) and ionic liquids with halogen element served as halogen source in most cases.…”
