· Ni2 O4

Ni₂O₄ is a nickel oxide semiconductor compound that exists as a mixed-valence nickel oxide system, often studied as a spinel-related or layered oxide structure. This material is primarily investigated in research contexts for energy storage and catalytic applications, where its variable oxidation states and ionic conductivity make it of interest for battery electrodes, supercapacitors, and electrocatalysis—particularly in oxygen reduction and evolution reactions relevant to fuel cells and water splitting devices.

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.
