Tribocatalytic degradation of dyes by tungsten bronze ferroelectric Ba_2.5Sr_2.5Nb₈Ta₂O₃₀ submicron particles.

ABSTRACT: Searching for a new approach in environmental remediation in terms of dye degradation is important in industrialized society. In this work, ferroelectric Ba_2.5Sr_2.5Nb₈Ta₂O₃₀ (BSNT) submicron powders prepared by the high-temperature solid-phase method are used for dye degradation under magnetic stirring. The dye in solution can be quickly degraded by magnetically stirring BSNT submicron particles in the dark in ambient temperature conditions. More importantly, the degradation efficiency can be greatly improved through simple modification of the stirring materials from glass to polypropylene, with a degradation efficiency of rhodamine B as high as 99% in 1.5 h at a gentle stirring speed of 300 rpm. Control experiments reveal that the deg
