Photocatalytic, piezocatalytic, and piezo‐photocatalytic effects in ferroelectric (Ba 0.875 Ca 0.125 )(Ti 0.95 Sn 0.05 )O 3 ceramics

Ba 0.875 Ca 0.125 Ti 0.95 Sn 0.05 O 3 (BCT‐Sn) was examined for photocatalytic, piezocatalytic, and piezo‐photocatalytic effects. BCT‐Sn powder was poled through corona poling and it was found that poling induces significant impact on photocatalysis. This material was also able to degrade dye (Methylene blue) using poled powder under ultrasonication (piezocatalysis). There was a remarkable effect in dye degradation which is a clear indication of the importance of piezocatalytic behavior in catalytic reactions. Moreover, the piezo‐photocatalytic effect (piezocatalysis + photocatalysis) was also investigated. Results suggested an enormous scope of ferroelectric materials in the field of catalysis.
