· PdS

Palladium sulfide (PdS) is a direct-bandgap semiconductor compound combining palladium and sulfur, belonging to the metal chalcogenide family. While largely in the research phase, PdS is investigated for optoelectronic and photocatalytic applications due to its semiconducting properties and potential for tailoring band structure through nanostructuring. Interest in this material centers on catalysis, photoelectrochemistry, and emerging photonic devices where conventional semiconductors (silicon, GaAs) prove inefficient or incompatible.

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.
