A pyro-electro-chemical catalytic dye decomposition using lead-free BaTiO 3 nanofibers was realized under room-temperature cold-hot cycle excitation (30-47 • C) with a high Rhodamine B (RhB) decomposition efficiency~99%, which should be ascribed to the product of pyro-electric effect and electrochemical redox reaction. Furthermore, the existence of intermediate product of hydroxyl radical in pyro-electro-chemical catalytic process was also observed. There is no significant decrease in pyro-electro-chemical catalysis activity after being recycled five times. The pyro-electrically induced pyro-electro-chemical catalysis provides a high-efficient, reusable and environmentally friendly technology to remove organic pollutants from water.
