Enhanced photocatalytic hydrogen generation using polymorphic macroporous TaON

Adv Mater. 2012 Jul 3;24(25):3406-9. doi: 10.1002/adma.201201193.

Abstract

Macroporous TaON (mac-TaON) is prepared using polymer sphere templating and controlled ammonolysis. In contrast to typical powder synthesis, which gives the β polymorph, mac-TaON is a mixture of β and γ polymorphs. mac-TaON shows twice the activity for photocatalytic hydrogen generation in comparison to mac-TaON when normalised for surface area.
