semiconductor

· O8 Ni2 Se2

O8Ni2Se2 is a nickel selenide compound semiconductor, likely a layered or mixed-valence phase combining nickel and selenium with oxygen incorporation. This is primarily a research and development material explored for energy storage, catalysis, and optoelectronic applications rather than an established commercial product. The material family is of interest for electrocatalytic water splitting, battery electrodes, and photoresponse devices due to the combined electronic properties of transition metal selenides with oxygen doping.

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.
