Enhanced Piezocatalytic Performance of BaTiO3 Nanosheets with Highly Exposed {001} Facets

Abstract: Piezocatalysis has gradually come into the limelight due to its great potential for solving energy shortages and environmental pollution problems. However, limited piezocatalytic efficiency is a severe bottleneck for its practical applications. Here, well-defined BaTiO 3 nanosheets with highly exposed {001} polar facets are successfully synthesized to enhance the piezocatalytic activity. The [001] piezoelectric polarization can drive the carriers to migrate to the surface along the out-of-plane direction. The … Show more

“…For example, BaTiO 3 nanosheets with highly exposed {001} polar facets exhibit enhanced piezocatalytic activity. 38 The {001} polar facet can drive the carriers to migrate to the surface along the out-of-plane direction. This polar surface provides abundant active sites for the piezocatalytic reaction.…”

“…Tang et al synthesized the BaTiO 3 nanosheets with highly exposed polar facets to enhance the piezocatalytic activity. Thanks to the obvious piezoelectric polarization of polar facets, the BaTiO 3 nanosheets displayed more outstanding piezocatalytic performance for pollutant degradation and H 2 production compared with BaTiO 3 nanoparticles [24] . The above researchers improved the piezoelectric catalytic performance of BaTiO 3 by regulating the morphology, but BaTiO 3 still exists the disadvantage of fast carrier recombination, which limits the further improvement of its performance.…”

“…Mesocrystals are highly ordered superstructures with a high degree of crystallinity and oriented subunit alignment. 20 For comparison, less transparent films were studied that consisted of aggregated small anatase polycrystals arranged without a preferred orientation (see Scheme 1b). The visible light photocatalytic performance of the three catalysts was evaluated for two model reactions, methanethiol (CH 3 SH) removal by catalytic oxidation and H 2 evolution by reducing water, which are two redox reactions.…”
