CTAB-assisted hydrothermal synthesis of silver vanadates and their photocatalytic characterization

Photocatalytic Activity of Novel Ag4V2O7 Photocatalyst Under Visible Light Irradiation

“…When PVP was introduced to the synthesis, pure Ag 4 V 2 O 7 still was obtained. Distinguishing from cetyltrimethylammonium bromide (CTAB, C 19 H 49 BrN) reported in some literatures, PVP significantly influenced the morphology of Ag 4 V 2 O 7 crystal. As presented in Fig.…”

“…Due to its high photocatalytic activity, Ag 3 VO 4 has been the focal point of the photocatalytic study among silver vanadates. However, Ag 4 V 2 O 7 material often coexisting with Ag 3 VO 4 in the synthesis always is neglected by researchers, due to it performing no photocatalytic activity for O 2 evolution and low activity in degradation of isopropanol and benzene vapors . However, the photocatalytic activity of materials was affected significantly by their physical properties including size, morphology, microstructure, crystallizability, etc., which were controlled by the synthesis conditions .…”

“…However, the photocatalytic activity of materials was affected significantly by their physical properties including size, morphology, microstructure, crystallizability, etc., which were controlled by the synthesis conditions . Ag 4 V 2 O 7 was usually synthesized using a surfactant‐assisted hydrothermal method in neutral solution . Compared with Ag 3 VO 4 , its morphology which is important for the performance and application of a material was more easily controlled by synthesis conditions.…”

In situ DRIFT and kinetic studies of photocatalytic degradation on benzene vapor with visible-light-driven silver vanadates

“…4, the XRD patterns of the samples synthesized at 140 • C for various durations consisted of pure ␣-Ag 3 VO 4 or mixed phases of Ag 4 V 2 O 7 and ␣-Ag 3 VO 4 . The CTAB-SVO samples, prepared by the addition of cetyltrimethylammonium bromide (CTAB, C 19 H 49 BrN), were characterized to be the pure Ag 4 V 2 O 7 crystalline [34]. The GC/MS was used to investigate the intermediates or byproducts occurred during the photocatalytic oxidation of benzene.…”

On the heterostructured photocatalysts Ag3VO4/g-C3N4 with enhanced visible light photocatalytic activity

“…The general methods for preparing Ag 3 VO 4 include solid-state reaction [44], hydrothermal reaction [45] and deposition [43]. Although the pure Ag 3 VO 4 shows excellent photocatalytic activity, the Ag 3 VO 4 is also limited by its low quantum yield.…”
