Synthesis and photocatalytic activity of porous bismuth oxychloride hexagonal prisms.
Porous BiOCl hexagonal prisms have been successfully prepared through a simple solvothermal route. These novel BiOCl HPs with porous structures are assembled from nanoparticles and exhibit high activity and selectivity toward the photocatalytic aerobic oxidation of benzyl alcohol to benzaldehyde and degradation of methyl orange.
متن کاملVacancy associates promoting solar-driven photocatalytic activity of ultrathin bismuth oxychloride nanosheets.
Crystal facet engineering of semiconductors is of growing interest and an important strategy for fine-tuning solar-driven photocatalytic activity. However, the primary factor in the exposed active facets that determines the photocatalytic property is still elusive. Herein, we have experimentally achieved high solar photocatalytic activity in ultrathin BiOCl nanosheets with almost fully exposed ...
متن کاملDefective TiO2 with oxygen vacancies: synthesis, properties and photocatalytic applications.
Titanium dioxide (TiO2), as an important semiconductor metal oxide, has been widely investigated in the field of photocatalysis. The properties of TiO2, including its light absorption, charge transport and surface adsorption, are closely related to its defect disorder, which in turn plays a significant role in the photocatalytic performance of TiO2. Among all the defects identified in TiO2, oxy...
متن کاملOxygen vacancy induced bismuth oxyiodide with remarkably increased visible-light absorption and superior photocatalytic performance.
With the increasingly serious environmental problems, photocatalysis has recently attracted a great deal of attention, with particular focus on water and air purification and disinfection. Herein, we show an electroreduction strategy to improve significantly the solar absorption and donor density of BiOI nanosheet photocatalyst by introducing oxygen vacancies. These oxygen-deficient BiOI nanosh...
متن کاملEpitaxial growth of silver chloride crystals on bismuth oxychloride.
In this work, studies of morphological and structural characteristics of BiOCl/AgX heterostructures (X = Cl, I) synthesized using ion-exchange reactions have been conducted. It was found that silver chloride (AgCl) crystals precipitating on the surface of bismuth oxychloride crystals show orientation ordering with the (001)BiOCl||(100)AgCl crystallographic relationship. Using two synthesis rout...
