Paradigms of Titanate Centered Energy Materials

Titanate-centered perovskites are an important class of crystalline materials with outstanding structural and property tunability. Recently, titanate perovskites have been extensively investigated as new-generation materials for various energy-allied applications, together with photovoltaic cells, light emitting diodes, photo detectors and lasers, for their exceptional optical and electronic properties. With increasing attention on the development of nanotechnology and multidisciplinary research, scientists have been trying to downscale the titanate perovskite structures into the nanoregime, so as to further boost their performances and applications. Compared with bulk perovskite materials, perovskite nanomaterials exhibit a series of advantages, such as fabrication of thin films and flexible devices and PNMs display high process ability. Perovskite nanomaterials feature rich and controllable facets and active sites. Besides benefiting from the small-size effect and quantum effect,
