Effect of Ce on piezo/photocatalytic effects of Ba0.9Ca0.1CexTi1-xO3 ceramics for dye/pharmaceutical waste water treatment
Source abstract
Abstract
Abstract Ba0.9Ca0.1CexTi1-xO3 (x = 0, 0.1, 0.12 and 0.15) ferroelectric ceramics were fabricated via conventional solid-state reaction route. Ba0.9Ca0.1CexTi1-xO3 (BCT-Ce) powder was poled using corona poling. Systematic investigation was carried out for microstructural, photocatalytic and piezocatalysis performance of various compositions of poled and unpoled Ba0.9Ca0.1CexTi1-xO3 ceramics. To assess catalytic activities, rhodamine B (RB) dye, methylene blue (MB) dye and diclofenac (pharmaceutical compounds) were degraded from water under ultrasonication (piezocatalysis) and using 420 nm light (photocatalysis). Photocatalytic activities were improved by almost 100% in poled samples (as compare to the that of observed from unpoled samples) of all the compositions understudy. Incorporation of Ce in Ba0.9Ca0.1TiO3 (BCT) induces photocatalytic activity in visible region along with enhancement in piezocatalytic performance.
