Intermediate ferroelectric phase driven ferroelectric-relaxor crossover and superior storage properties in phase boundary engineered BCZT ceramics

Solvothermal synthesis of (Na0.8K0.2)0.5Bi0.5TiO3 piezoelectric catalyst with morphotropic-phase-boundary structure for efficient dye degradation

“…21 The MPB is a highly sensitive region, where even slight changes in the phase can cause a sudden change in the piezoelectric properties of the material. [22][23][24] In recent years, as environmental pollution has become increasingly severe, people have started seeking lead-free piezoelectric materials to replace PZT-based ones, which has led to the development of ABO 3 perovskite lead-free piezoelectric materials. 25,26 Na 0.5 Bi 0.5 TiO 3 (BNT) is well-known among ferroelectric materials for its excellent piezoelectric properties and conductivity (E 10 À5 S m À1 ).…”
