“…Due to the unique atomic-level spontaneous symmetry breaking, ferroelectric materials have been widely investigated in various fields, such as ferroelectric memory, 1 ultrasonic transducers, 2 pressure sensors 3 and catalysts. 4 In recent years, ferroelectric semiconductors have demonstrated great potential in photocatalytic solar energy to hydrogen conversion, 5,6 where the built-in electric field in materials could facilitate the separation and transport of the photogenerated carriers and thus high photocatalytic capacities. The wide band gap ferroelectric photocatalysts explored exhibit excellent photocatalytic performance under UV light irradiation, such as PbTiO 3 , 7 BaTiO 3 , 8 Na 0.5 Bi 0.5 TiO 3 , 9 and Bi 3 TiNbO 9 , 10,11 among which, PbTiO 3 is regarded as one of the most promising photocatalysts because of its high built-in electric field (∼3.6 kV cm −1 ), adjustable micromorphology and band gap (∼2.8 eV).…”

Exotic physical phenomena in solids emerge with changes of nonlinear responses (e.g., polarization hysteresis under an electric field) of order parameters to external stimuli. In epitaxial ferroelectric films, polar ordering states of electric dipole moments cooperate with local disorder originating from thicknessdependent mitigation of misfit strain inherently and/or chemical off-stoichiometry extrinsically. The mutual interaction of electric polarization with both intrinsic and extrinsic factors in ferroelectric thin films produces sizable modification of ferroelectric hysteretic characteristics. Herein, we demonstrate defect-induced manipulation of ferroelectric hysteresis in epitaxial Bi 1/2 (Na,K) 1/2 TiO 3 films. Notably, pinched hysteresis loops and linked double switching current behaviors are observed with the formation of screw dislocations on the surfaces of lead-free ferroelectric films grown at high temperatures. Plausibly, structural transitions of tetragonal phases to rhombohedral-like monoclinic symmetry driven by Na enrichment enable the appearance of ferroelastic domain variants, of which screw dislocations can be created to accommodate local stress at the boundaries. Polarization switching at the dislocation-mediated ferroelastic domain walls has been also limited and thereby, single ferroelectric hysteresis loops evolve to double-like hysteresis loops. Our result of defect-engineered ferroelectric hysteresis is of potential interest for designing advanced electronic devices such as functional energy storage and harvesters with high performance.

The conventional heterogeneous photo-Fenton systems suffer from limited surface active sites, sluggish Fe 3+ /Fe 2+ cycle, and low activation efficiency of hydrogen peroxide, thus limiting their applications. Herein a 0D/ 3D FeOOH/BaTiO 3 composite photo-Fenton catalyst system was proposed. The typical microstructure in which FeOOH nanoparticles uniformly anchored on the flower-like BaTiO 3 microsphere endows the composite catalysts with abundant active sites and intimate heterojunctions, which are conducive to charge carrier separation and transportation, as confirmed by the electrochemical and XPS characterization results. Benefiting from these advantages, the degradation rate of RhB with 1:4 FeOOH/BaTiO 3 was significantly increased to 0.23 min −1 , which was 40.5 and 7.9 times higher than that of BaTiO 3 and FeOOH when a trace amount of H 2 O 2 (6 mM) was present. In addition, the catalysts also showed superior degradation efficiency in decomposing the antibiotic TC and possessed high recycle stability. The triggered Fenton reactions give rise to abundant • OH, which was confirmed to be the dominated active species. According to the band structure analysis and control experiment results, it was believed the smooth photoelectron transfer from BaTiO 3 to FeOOH accelerated the Fe 3+ /Fe 2+ cycle, facilitated activation of H 2 O 2 , and boosted photo-Fenton reactions. This work provides a perspective on the design of high-performance photo-Fenton catalysts to tackle wastewater treatment.
