Sonochemical-assisted synthesis of Pt/Bi2MoO6 nanocomposites for efficient photodegradation of rhodamine B

Soraya Pinchujit et al.

Summary: Heterostructure Pt/Bi2MoO6 nanocomposites with different weight contents of loaded Pt were synthesized using a sonochemical-assisted deposition method and used to degrade rhodamine B under visible radiation. Various techniques were employed to characterize the nanocomposites and a photocatalytic mechanism was proposed. The heterostructure Pt/Bi2MoO6 nanocomposites showed higher photocatalytic activity compared to pure Bi2MoO6 nanoplates, attributed to the surface plasmon resonance effect of Pt-0 nanoparticles generating h(+) and center dot O-2(-) radicals for photodegradation of RhB molecules.

Development of visible light-driven SrTiO3 photocatalysts for the degradation of organic pollutants for waste-water treatment: Contrasting behavior of MB & MO dyes

Sonali Mehra et al.

Summary: Semiconductor photocatalysts, such as SrTiO3 nanoparticles, are widely used for degrading organic pollutants in water through photocatalysis. This study focuses on the photocatalytic degradation of methyl orange and methylene blue using SrTiO3 as a photocatalyst in de-ionized and hard water. The addition of Ag and Au nanoparticles to SrTiO3 enhanced its photocatalytic activity, with Au yielding better results. However, bare SrTiO3 and its composites did not show any degradation of methyl orange in both de-ionized and hard water.

Preparation and characterization of highly efficient Z-scheme oxygen vacancy-BiOBr/CoFe2O4 heterojunction photocatalyst driven by visible light for antibiotic degradation

Pengfei Zhu et al.

Summary: In this study, a magnetic oxygen vacancy-BiOBr/CoFe2O4 (OV-BiOBr/CoFe2O4) composite with a Z-scheme heterojunction is prepared. The composite shows excellent photocatalytic performance for various antibiotics under visible light irradiation, and can be recovered and reused using an external magnetic field. The improved photocatalytic performance is attributed to the extension of the visible light response range, the increase of active sites, and the effective separation of electron hole pairs. Furthermore, a Z-scheme heterojunction electron transfer mechanism is proposed.

Summary: The BiVO4/GO/CoFe2O4 composite photocatalyst was successfully synthesized and its structure, composition, morphology, and optical properties were investigated. The results show that the composite photocatalyst has good degradation ability under visible light irradiation, and it exhibits good stability. The addition of GO promotes the separation of electrons and holes, while the addition of CoFe2O4 solves the problem of catalyst recycling and increases the specific surface area of the catalyst. The photocatalytic activity of the composite photocatalyst has been significantly improved, which is attributed to the construction of the Z-scheme heterojunction.
