Normally, only noncentrosymmetric structure of the materials can potentially be piezoelectric. Thus, it is limited in the field of piezoelectricity for the centrosymmetric structure of the material. In this work, the performance of piezoelectricity is successfully achieved from centrosymmetric SrFeO3‐x by modulating oxygen vacancies, which have a surface piezoelectric potential up to 93 mV by using Kelvin‐probe force microscopy (KPFM). Moreover, the piezoelectric effects of SrFeO3‐x are also evaluated by piezoelectric catalytic effect and density functional theory calculations (DFT). The results show that the piezo‐catalytic degradation of tetracycline reaches 96% after 75 min by ultrasonic mechanical vibration and the production of H2O2 by SrFeO3‐x piezoelectric synthesis could reach 1821 µmol L−1. In addition, the DFT results indicate that the intrinsic effect of oxygen vacancies effectively promotes the adsorption and activation of O2 and H2O as well as intermediates and improves the piezoelectric catalytic activity. This work provides an effective basis for realizing the piezoelectricity of centrosymmetric materials and regulating the development of piezoelectric catalytic properties.

“…[2][3][4][5][6][7] For example, both theoretical and experimental studies have consistently demonstrated the piezoelectric properties of MoS 2 monolayer and h-BN. [8][9][10] Other 2D materials, such as TMDC, 11 group-IV monochalcogenides, 12 and group-III monochalcogenides, 13 have been predicted to possess intrinsic in-plane piezoelectric properties, albeit with relatively small piezoelectric coefficients. Research studies indicate that ferroelectric-based piezoelectric materials, as a significant category, exhibit high piezoelectric coefficients, ranging widely from around a dozen pC N À1 for Bi 3 TiNbO 9 14 to approximately 4100 pC N À1 for Sm-doped PMN-PT 15 single crystals.…”

Saturated hydrogenation of aromatic amines is a crucial methodology for synthesizing alicyclic amines. The dispersion of Ru atoms occurred after chemical reduction treatment, which was constrained to B and N coordination, further promoting the Ru species’ uniform distribution through interaction with the B–N bond of boron nitride. Moreover, the Ru coordinated with h-BN and further formed the stable catalytic active center. By virtue of its excellent stability, the hydrogenation of MDA executed in the fixed-bed reactor could run for more than 200 h. However, the density functional theory showed that the hydrogenation rate of the second benzene ring was comparatively slower because of the strong intermediate adsorption during the conversion from 4,4′-diaminodiphenylmethane to 4,4′-diaminodicyclohexylmethane. Furthermore, Ru/h-BN exhibited excellent performance in the hydrogenation of other aromatic amines, resulting in corresponding alicyclic amines. Therefore, this research offers a stable and effective catalyst for the green hydrogenation of aromatic amines leading to the production of alicyclic amines.
