摘要：
Rodlike CaTiO3 was prepared by a simple thermal method. The as-prepared samples presented relatively enhanced photo induced charge separation and high photocatalytic activity toward methyl orange in aqueous solution. The band gap of the CaTiO3 with special morphology was narrowed. The photoreactivity observed on CaTiO3 was attributed to the large amount of active sites, great oxidation potential of photogenerated holes and high separation efficiency of photogenerated electrons and holes.
