Crystal facet tailoring arts in perovskite oxides

摘要: Crystal facet engineering is an important strategy for fine-tuning the physical and chemical properties in many fields, which will provide effective route to fundamentally understand relationship between surface structure electron state. Many researchers have worked on technological performance improvement of noble metal nanoparticles simple oxides by tailoring their crystal facets. Perovskite are most prominent mixed-oxide materials field heterogeneous catalysis due acceptable catalytic activity thermal stability. However, utilization perovskite still limited comparison with catalysts because stable usually terminated non-catalytically active High-index may be improve catalysts. So far, only several been reported well-defined polyhedral shapes. Herein, we review recent progress arts oxides. This begins a general introduction related behavior potential facet-dependent applications. Then, principles growth discussed. The principle possible grown facets proposed. Various shape reviewed four parts: (i) tungsten molybdenum trioxide (A0B+6O3); (ii) niobate tantalite (A+1B+5O3); (iii) titanate zirconate (A+2B+4O3); (iv) ferrite, chromite manganite (A+3B+3O3), including mixed-valence state compounds. mechanism discussed next section. Finally, overview promising future dependent applications given as perspective outlook. Fundamental understanding expected open up strategies development highly efficient oxide materials.
