Description
Summary:TiO 2 hollow structures have important applications in high performance lithium ion batteries and efficient photocatalysis. In contrast to the conventional synthesis routes where various soft or hard templates are usually put into use, the direct growth of uniform TiO 2 hollow nanocrystals is presented. The growth mechanism, lithium ion battery performance, and photocatalytic activity of the resultant TiO 2 hollow nanocrystals are thoroughly investigated. TiO 2 hollow nanocrystals can be synthesized through a mechanism analogous to the nanoscale Kirkendall effect. The hollow structure results in highly active photocatalysis, high rate capability, and stable cycling. Herein, we report a simple nanoscale Kirkendall effect method to synthesize TiO 2 hollow nanocrystals. The fabrication process is cheap, convenient and scalable, while the produced TiO 2 hollow nanocrystals exhibit excellent electrochemical and photochemical properties.
