In this work, pyro-catalytic effect is realized in hydrothermally-synthesized pyro-electric NaNbO₃ shape-controllable nanoparticles via the product of pyro-electric effect and electrochemical redox. A pyrocatalysis is designed to decompose dye wastewater. Under the 23-50 °C heating-cooling cycle, the maximum pyro-catalytic decomposition ratio of NaNbO₃ nanorods, nanosheets and nanocubes are 96%, 76% and 33%, respectively. The pyro-catalytic effect of NaNbO₃ nanoparticles is potential in developing a environmentally-friendly technology for room-temperature pyrocatalysis through utilizing natural heat energy.
