Silver Tantalum Sulfide (AgTaS3) Powder

2D Materials, Low Dimensional Materials, Transition Metal Chalcogenides (TMCs)

High quality, high purity AgTaS3 powder

Suitable to process nano-plates into few-layer films

2D layered silver tantalum sulfide (AgTaS₃) belongs to the family of ternary metal sulfides which are promising alternatives to noble metals for its excellent redox reversibility, high electronic conductivity and capacitance. Binary metal sulfides can be used as electrode materials for lithium-ion batteries (LIBs), supercapacitors (SC), and solar cells applications.

Atomically thin AgTaS₃ layers can be synthesized through a facile probe sonication exfoliation of either bulk crystals or powder.

Structure of Silver Tantalum Sulfide Powder

AgTaS₃ crystallizes in the orthorhombic Cmcm space group in three dimensional structure. Ta⁵⁺ is bonded in a 8-coordinate geometry to eight S^2- atoms while Ag⁺ is bonded in a 2-coordinate geometry to six S^2- atoms. S^2- sites are inequivalent in the structure with each of one set of S^2- ions is bonded in a 3-coordinate geometry to three equivalent Ta⁵⁺ and two equivalent Ag⁺ atoms while each of the other set S^2- ions is bonded to two equivalent Ta⁵⁺ and two equivalent Ag⁺ atoms to form corner-sharing [STa2Ag2] tetrahedra.

The layer is composed of Ta-centred bicapped trigonal prisms stacked on top of each other by sharing triangular faces with each layers are held together through van der Waals interactions. Ag⁺ions reside in the distorted octahedral sites between the layers.

Applications of Silver Tantalum Sulfide Powder

AgTaS₃is nonlinear in optical response thus can have applications in signal processing, optical computers, ultrafast switches, ultra-short pulsed lasers, sensors and laser amplifiers,

AgTaS₃also may also be used for for low-power and high-speed electronics.

Synthesis

Obtained via the CVT method, AgTaS₃powder with purities of over 99.995% have been achieved.

Usage

AgTaS₃ powder is suitable for liquid chemical exfoliation to process AgTaS₃ nano-plates down to few-layer films. High-quality, high-purity AgTaS₃ powder is also used for CV deposition of ultra-thin single or few-layer films.
