ZnS nanospheres/reduced graphene oxide photoanode for highly efficient solar water oxidation
One of the most important challenges in renewable energy conversion is construction of an earth-abundant,
active, and stable water splitting photoelectrocatalyst operating at all pH values. In this work, ZnS ...
Photostability and visible-light-driven photoactivity enhancement of hierarchical ZnS nanoparticles: The role of embedment of stable defect sites on the catalyst surface with the assistant of ultrasonic waves
Zinc sulfide is a UV-active photocatalyst and it undergoes photocorrosion under light irradiation.
In this work, the defect sites on ZnS nanoparticles (NPs) surfaces were induced with the help of powerful
ultra- ...
Photocatalytic Degradation and Mineralization of Reactive Textile Azo Dye Using Zinc Sulfide Nanoparticles Prepared by Ultrasound
The photocatalytic activity of zinc sulfide (ZnS) nanoparticles (NPs) prepared under different conditions were compared for degradation of anionic dye reactive black 5 (RB5) in aqueous solutions under UV-light irradiation. ...
Influence of preparation methods of microwave, sol–gel, and hydrothermal on structural and optical properties of lanthania nanoparticles
In this work, the nearly pure hexagonal phase of lanthania nanoparticles (NPs) was successfully synthesized using three methods: microwave, sol–gel, and hydrothermal. The samples were characterized using nine techniques ...
Lanthania Colloidal Nanoparticles: Hydrothermal Synthesis, Structural, and Rheological Properties
In this work, for the first time, the rheological properties of nanofluids of lanthania nanoparticles (NPs) in ethylene glycol (EG) as functions of shear rate, volume fraction, and temperature were measured. The results ...
ZnS@ reduced graphene oxide nanocomposite as an effective sunlight driven photocatalyst for degradation of reactive black 5: A mechanistic approach
