Molybdenum diselenide (MoSe₂) is a transition metal dichalcogenide compound featuring molybdenum bonded to selenium in a layered crystal structure. This material has emerged as a high-potential semiconductor and catalyst in electrochemistry and energy applications, notably as an alternative to precious-metal catalysts in hydrogen evolution reactions and as a component in photovoltaic and optoelectronic devices. Its indirect bandgap, strong light absorption, and tunable electronic properties make it valuable for researchers developing next-generation energy conversion systems and 2D material-based technologies where performance and cost compete with traditional catalysts like platinum.

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.
