Lead-Free Bi(0.5)Na(0.5)TiO(3) Ferroelectric Nanomaterials for Pyro-Catalytic Dye Pollutant Removal under Cold-Hot Alternation

In this work, explicitly pyro-catalytic performance is observed in sol-gel-synthesized ferroelectric Bi(0.5)Na(0.5)TiO(3) lead-free nanomaterials, and its application for dye wastewater purification is also actualized under temperature fluctuations varying from 23 °C to 63 °C. The decomposition rati...

description In this work, explicitly pyro-catalytic performance is observed in sol-gel-synthesized ferroelectric Bi(0.5)Na(0.5)TiO(3) lead-free nanomaterials, and its application for dye wastewater purification is also actualized under temperature fluctuations varying from 23 °C to 63 °C. The decomposition ratios of the pyro-catalytic Bi(0.5)Na(0.5)TiO(3) nanomaterials on Rhodamine B, methyl blue and methyl orange can reach 96.75%, 98.35% and 19.97%, respectively. In the pyro-catalytic process, the probed active species such as hydroxyl radicals, superoxide radicals and holes play an extremely important role in decomposing dye molecules. The ferroelectric Bi(0.5)Na(0.5)TiO(3) lead-free nanomaterials will have an excellent prospect for dye wastewater purification due to its explicit pyro-catalysis.
