Facile synthesis of AgBr nanoplates with exposed {111} facets and enhanced photocatalytic properties

Abstract

AgBr nanoplates with exposed {111} facets have been synthesized in high yield by a facile precipitation reaction, and the as-prepared nanoplates exhibited greatly enhanced photocatalytic properties for the degradation of organic pollutants, which may be primarily ascribed to the relatively higher surface energy of {111} facets.

Facile assembling of AgI/Ag3PO4 via dissolution–precipitation mechanism and its excellent photocatalytic activity for contaminant removal

“…Silver-salt photocatalysts, such as AgX (X = Cl, Br, I) [29][30][31], Ag 3 PO 4 [20,32,33], Ag 3 VO 4 [34], Ag 2 CrO 4 [35], Ag 2 CO 3 [36], Ag 2 MoO 7 [37] and AgNbO 3 [38] displayed excellent photocatalytic performance under visible light. The weak solubility [39,40] of silver-salt photocatalysts makes them achieve dissolution-precipitation equilibrium in water at room temperature.…”

Tailoring the shape of amorphous nanomaterials: recent developments and applications

“…This "structure" can generally be divided into four categories: size [33,34], shape [35][36][37][38], © Science China Press and Springer-Verlag Berlin Heidelberg 2015 SCIENCE CHINA Materials REVIEWS composition [39,40] and assembly [41,42]. Therefore, tailoring these structural factors to tune the properties of nanomaterials is regarded as a challenge that must be overcome to realize applications in nanotechnology.…”

Facile synthesis of hierarchical Ag3PO4/TiO2 nanofiber heterostructures with highly enhanced visible light photocatalytic properties

“…To better utilize the visible light, which accounts for ca. 45% of the solar energy, enormous efforts have been devoted over the past decades to exploiting the visible-light-driven photocatalysts, including N doped TiO 2 [4,5], AgBr [6][7][8], BiVO 4 [9,10], Bi 2 MoO 6 [11,12], CdS [13][14][15], Fe 2 O 3 [16,17], and so forth. Among those semiconductor materials, silver orthophosphate (Ag 3 PO 4 ) with a direct bandgap of ca.…”
