Journal ArticleDOI
Large-Scale Solid-State Synthesis of Sn–SnO2 Nanoparticles from Layered SnO by Sunlight: a Material for Dye Degradation in Water by Photocatalytic Reaction
TL;DR: Phase pure spherical Sn-SnO2 nanoparticles (∼ 50 nm) in gram level have been synthesized from well-defined SnO microplates using focused solar irradiation to improve charge separation efficiency and foster stability toward adverse environmental conditions.
Journal ArticleDOI
Tin oxide with a p–n heterojunction ensures both UV and visible light photocatalytic activity
TL;DR: Tuning of the tin oxide (SnO/SnO2) heterojunction has been made possible by heating the as-prepared p-type SnO semiconductor in air in a controlled fashion.
Journal ArticleDOI
A one pot synthesis of Au–ZnO nanocomposites for plasmon-enhanced sunlight driven photocatalytic activity
TL;DR: In this paper, the photocatalytic activity of the Au-ZnO nanocomposites was examined by the photodegradation of a series of cationic and anionic dye molecules such as rhodamine B, Congo red, methyl orange, methylene blue, and Rose Bengal.
Journal ArticleDOI
Hierarchical Gold Flower with Sharp Tips from Controlled Galvanic Replacement Reaction for High Surface Enhanced Raman Scattering Activity
TL;DR: In this article, the formation of AuF is carefully studied, and a spontaneous assembly mechanism is proposed, and the time-course experimental results show that the influence of electrostatic field force (EFF) of the charged resin beads is held responsible for prickly tipped AuF formation.
