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

In this work, using a simple one-step solvothermal method, a piezoelectric catalyst of (Na 0.8 K 0.2 ) 0.5 Bi 0.5 TiO 3 with a morphotropic phase boundary (MPB) was successfully prepared and applied to decompose methylene blue dye.
