· Mo3 W1 S8

Mo₃W₁S₈ is a mixed-metal transition metal dichalcogenide (TMD) compound combining molybdenum, tungsten, and sulfur in a layered crystal structure. This is an experimental/research material being investigated for its electronic and catalytic properties, as the tungsten doping modifies the electronic band structure and active sites compared to pure MoS₂. The material shows promise in electrocatalysis, particularly for hydrogen evolution reactions and water splitting, where the synergistic effects of Mo-W heteroatoms can improve activity over single-metal alternatives; it is also being explored in optoelectronics, energy storage, and sensing applications where 2D TMDs with engineered defects and dopants offer tunable performance.

RoHS, REACH, and Prop 65 statuses are validated against official substance lists (ECHA SVHC Candidate List, OEHHA Prop 65, RoHS Annex II). Other regulations are estimated from composition and material classification. All screening is a starting point for due diligence — always verify with your supplier before making compliance decisions.
