Pulse-Poled Porous BaTiO3 Ceramic for Piezocatalysis Applications

Abstract

The porous ceramic BaTiO3 pellets were synthesized by using polymethyl methacrylate (PMMA) as a pore former in 0–30 wt% proportion through solid route reaction method. Further, the synthesized porous BaTiO3 ceramic pellets were poled via pulse poling; a non traditional poling technique and their piezoactivity were examined by means of piezovoltage. There was significant enhancement in piezoelectric coefficient (d33) of porous BaTiO3 ceramic pellets using pulse poling technique. Later on, in the present study a quantitative analysis was done through comparision by degrading an organic dye by using poled/ unpoled porous BaTiO3 sample.
