Abstract: In the present work, an easy precipitation method without presence of surfactants is applied to the synthesis of the hexagonal phase of metastable β-Ag2WO4 microcrystals at room temperature. In addition, we report for first time the in situ formation, growth, and subsequent reabsorption of Ag nanoparticles on the surface of this metastable phase, which was induced by electron beam irradiation under high vacuum.

Surfactant-Mediated Morphology and Photocatalytic Activity of alpha-Ag2WO4 Material Abstract: In the present work, the morphology (hexagonal rod-like vs cuboid-like) of an alpha-Ag2WO4 solid-state material is manipulated by a simple controlled-precipitation method, with and without the presence […]
