Randomized trial demonstrates enhanced photocatalytic activity in titania spheres, indicating novel material applications.
Urchinlike TiO 2 spheres with tunable chamber structure were synthesized using a template-free solvothermal method. The unique sphere-in-sphere chamber structure allows multiple reflections of UV light resulting in greatly enhanced photocatalytic activity. This work provided novel structural platforms for novel materials and device applications.
