Piezo-photoelectronic coupling effect of BaTiO3@TiO2 nanowires for highly concentrated dye degradation

The induced built-in electric field by piezoelectric materials has proven to be one of the most effective strategies for modulating the charge-transfer pathway and inhibiting carrier recombination. In this work, a series of core-shell structured BaTiO3@TiO2 nanowires ([email protected]2 NWs) heterojunctions were synthesized and the significant coupling effects between BaTiO3 (BT) and TiO2 resulted in surperior piezo-photocatalytic performance,...
