Nano Silver Vanadate AgVO₃: Synthesis, New Functionalities and Applications

Abstract

Silver vanadates have been widely investigated because of their many interesting properties and their potential use in several applications. In addition to this, a large number of groups have investigated silver vanadates in the form of nanostructures. Here, we address first the synthesis and properties of nanosilver vanadate. Different techniques, such as precipitation, thermal decomposition, hydrothermal treatment, and sol-gel, are among the methods that have been employed for the controlled synthesis of silver vanadate. The use of nanosilver vanadate for the development of novel electronic devices, catalysts, and antibacterial agents for industry and biomedical applications will then be discussed. In this sense, the present review highlights the major advances regarding the synthesis, properties and applications of nanostructured silver vanadates.

Electrodeposition of Silver Vanadate Films: A Tale of Two Polymorphs

“…In particular, AgVO 3 has attracted considerable interest because of its wide-ranging practical applications including batteries, sensors, antibacterial formulations, and as photocatalysts for pollutant decomposition. [2,15] The structural aspects of the two polymorphs and the component AgO x and VO 4 clusters in them along with their relative juxtapositions, are well described in the literature. [2] The most common are the metastable α and thermodynamically-stable β polymorphs with monoclinic space groups Cm and C2/c, respectively.…”

“…2). [2] The most common are the metastable α and thermodynamically-stable β polymorphs with monoclinic space groups Cm and C2/c, respectively. [3][4][5][6][7][8][9][10][11][12][13][14][15][16] Polymorphism in AgVO 3 has provided a platform for many studies; this compound exhibits up to four different crystallographic forms, namely, α, β, γ and δ forms.…”

“…As reviewed by other authors, [2] this ternary compound has been synthesized in a range of nanostructures (nanorods, nanobelts, nanoribbons, and nanowires) using methods ranging from hydrothermal (most common) to biomineralization along with other hybrid and more esoteric approaches including the use of pulsed laser deposition, microwave assistance, ultrasonic agitation etc. Conspicuous in its absence is the use of electrodeposition [17][18][19][20][21][22][23] for AgVO 3 synthesis.…”

Synthesis of β-AgVO3 nanowires by hydrothermal and precipitation routes: a comparative study

“…Their properties are directly dependent on their composition, size, crystalline structure and surface characteristics. The most common form of silver vanadate is AgVO 3 , a stable one-dimensional material with several applications, such as: sensors, batteries, photocatalytic for dye photodegradation, antimicrobial agents, and additive for dental prostheses [10][11][12].…”

Thermal activation of charge carriers in ionic and electronic semiconductor β-AgIVVO3 and β-AgIVVO3@VV1.6VIV0.4O4.8 composite xerogels

“…The rich crystal chemistry of vanadium oxides (VO) and silver vanadium oxides (SVO) is one of the key factors that govern their physical and chemical properties. Due to their labile nature, these complex oxides have been applied with outstanding performances as cathode materials for batteries, 2-4 photo-catalysts, 1,5-12 antibacterial agents, [13][14][15][16][17] photochromic devices [18][19][20] or as active components of sensing devices, just to mention some examples. [21][22][23] In addition, the size-reduction of VO and SVO down to the nano-scale increases the surface area and modies their surface chemistry, improving even more their performance in the above mentioned applications.…”
