| Application: | 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. |
| General description: | 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. |
