| 3 | Oxalic acid functionalization of BaTiO_(3) nanobelts for promoting their piezo-degradation organic contaminants显示文摘Surface functionalization of piezoelectric greatly determines its piezo-catalytic activity and selectivity in that functional group affect specific reactants’surface adsorption and activation abilities.Herein,we propose chemical functionalization on the surface of nano-scaled BaTiO_(3) piezoelectric via a one-pot hydrothermal process using polyethylene glycol as surfactant,and evaluate its piezo-catalytic activity and selectivity by degrading model antibiotic and dye reactants under ultrasonic vibrations.Acetate or/and oxalic unidentate ligands on the surface of BaTiO_(3) nanobelts can be formed by controlling precursor and hydrothermal parameters.Particularly,oxalic acid functionalized BaTiO_(3) nanobelts presented a high piezo-catalytic rate constant of 0.068 min^(-1) for Rhodamine B solution and maintained>87%degradation efficiency within 30 min under the condition of ultrasonic bath with 40 kHz and 100 W,which was mainly ascribed to piezo-sensitization effect.This work provides references for the preparation of chemical functionalized catalysts and also contributes to the development of novel catalysts for special applications. | Shitao Gao Hongjie Xing Jingji Zhang Yapi Liu Huiwei Du Zejie Zhu Jiangying Wang Xu Li Suwei Zhang Yaxuan Yao Lingling Ren | 2021 | Journal of Materiomics2021，7，6： | 1 |
