· JVASP-28847· W2SeS3

W2SeS3 is a ternary compound combining tungsten with selenium and sulfur, belonging to the family of layered transition metal chalcogenides. This material is primarily of research interest rather than established in widespread industrial use, studied for its potential as a semiconductor or energy storage component given the electronic properties typical of mixed-chalcogenide systems. Engineers would consider this material in emerging applications where the specific combination of tungsten with both selenium and sulfur offers advantages in catalysis, thin-film electronics, or electrochemical systems where alternative single-chalcogenide compounds are insufficient.
