Strain engineering is widely employed to manipulate the intrinsic relationship of activity and the crystal structure, while the mechanism and rational strategy toward high-performance devices are still under investigation. Here straining engineering is utilized to manipulate a series of a typical perovskite structures via introducing different types of heteroions (Bi 1– x M x FeO 3 , M = Ca 2+ or Y 3+ ion). The space group R 3 c in BiFeO 3 perovskites is found to be maintained with substituting a certain amount of heteroions at Bi 3+ sites (<5%), while it would shift into either space groups P 4 mm (with Ca 2+ substitute) or Pnma (with Y 3+ substitute) beyond some critical doping amounts (>5%). Such a transformation is linked with the mismatched crystal strain induced by the heteroions substituted at Bi 3+ sites, while the activity, stability, and energy storage capability of Bi 1– x M x FeO 3 have been essentially varied. The results offer a strategy for manipulating stability and activity of perovskites in electrochemical energy conversion and storage. |
