Beschreibung

Allgemeine Beschreibung

Red phosphorus is the most common allotrope ofphosphorus due to its relative stability compared to white phosphorus. It has a variety of uses including, but notlimited to, use as a catalyst, battery anode, flame retardant, and igniter.

Anwendung

Red phosphorus can be used as a:

• Photocatalyst for the formation of H₂ from water.
• Catalyst in the synthesis of tris(2-pyridyl)phosphine by reacting with 2-bromopyridine in the presence of a base.
• Flame retardant along with aluminum oxide in recycled poly(ethylene terephthalate).
• Anode material in combination with carbon composites for sodium-ion batteries.
