Investigation of titanium dioxide polymorph selectivity as influenced by the amorphous precursor state
Polymorphism in the titanium dioxide system provides an opportunity for enhancing performance and functionality through targeted synthesis of phases higher in energy than the most thermodynamically favorable phase. Both the anatase and brookite polymorphs are metastable relative to the most thermodynamically stable structure, rutile. Along with their metastability, these two polymorphs also exhibit photocatalytic activity. The ability to selectively synthesize each of these titanium dioxide polymorphs would prove invaluable in the pursuit of optimizing material properties for photocatalysis. A ...
