· Ni3 Se3

Ni₃Se₃ is a layered nickel selenide compound belonging to the family of transition metal chalcogenides, which are semiconducting materials with potential for energy conversion and catalytic applications. This material is primarily under research and development rather than established in high-volume production, with interest focused on electrochemical energy storage (batteries, supercapacitors) and electrocatalysis for hydrogen evolution and water splitting. Engineers consider nickel selenides as alternatives to precious-metal catalysts and as electrode materials where their layered crystal structure, variable oxidation states, and moderate electrical conductivity offer advantages in cost and performance compared to conventional semiconductors.

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.
