Solvothermal synthesis of BiOCl flower-like hierarchical structures with high photocatalytic activity

摘要: Abstract Flower-like BiOCl hierarchical structures were successfully synthesized in the presence of citric acid through a solvothermal process using methanol as solvent. The played significant roles, which functioned both chelating regent and structure-directing agent. as-synthesized flower-like particles assembled by numerous nanosheets with thickness ca. 15–20 nm. Importantly, such morphology exhibited higher photocatalytic activity than that commercial TiO 2 degradation methyl orange under either UV light or simulated sunlight illumination.
