Enhanced piezo-photocatalytic performance by piezoelectric and visible light photoexcitation coupling through piezoelectric Na0.5Bi0.5TiO3 micron crystals

“…[15][16][17][18][19][20][21][22][23][24][25][26][27] Aer the preliminary experiments showed an evolution of H 2 and O 2 by piezoelectric BaTiO 3 and ZnO through mechanically vibration, 18 piezocatalytic activities have been extensively demonstrated by various piezoelectric crystals. [15][16][17][18][19][20][21][22][23][24][25][26][27] In addition, coupling of piezocatalysis with photocatalysis processes, the catalytic performance can be improved when the piezoelectric materials were subjected to both mechanical vibration and light irradiation simultaneously. However, either ultraviolet (UV) or sun light was used in these reports due to the fact that all the related piezoelectric materials were wide band gap semiconductors.…”

“…[12][13][14][15][16][17] This piezoelectric eld can be directly acted as a natural driving force to promote electrochemical reactions, which could lead to performance gains for electrochemical catalysis, and thus a new concept called piezocatalysis has been developed. [15][16][17][18][19][20][21][22][23][24][25][26][27] Different from photocatalysis, the piezoelectric material has the ability to directly convert mechanical energy to chemical energy, which also can be used to mechanically driven water splitting and degradation of organic dye pollutants.

Magnetic-Electrospinning Synthesis of γ-Fe2O3 Nanoparticle–Embedded Flexible Nanofibrous Films for Electromagnetic Shielding

“…Electrospinning is undoubtedly the most widely used method for preparing nanofibrous films [30,31]. As-spun fibers with fascinating properties, such as large surface areas, high length-to-diameter ratios, flexible surface functionality, tunable surface morphologies, and superior mechanical performances, have recently attracted much attention and have a wide array of potential applications, including for thermal management [32,33], optoelectronics [34,35], sensors [36][37][38], catalysis [39,40], energy storage [41,42], tissue engineering [43], and drug delivery [44,45]. The increasing demand in recent years for the precise preparation of nanofibrous films has accelerated the development of new-concept electrospinning techniques.…”

Effect of poling on piezocatalytic removal of muti‐pollutants using BaTiO3

“…Some of the unexplored issues are quantitative role of piezoelectric nature, role of semiconductor nature, and effectiveness of piezocatalytic for degradation of various organic pollutant such as bacterial cell, dyes, pharmaceuticals etc 10‐12 . Most of the recent studies have reported piezocatalysis using BaTiO 3 , Sr 0.7 Ba 0.3 Nb 2 O 6 , Bi 4 Ti 3 O 12 , LiNbO 3 , K 0.5 Na 0.5 NbO 3 , Bi 0.5 Na 0.5 TiO 3, Pb(Zr,Ti)O 3 , Ba 0.85 Ca 0.85 Ti 0.90 Zr 0.10 O 3 (BCZTO), and ZnO 13‐21 . Among these, BaTiO 3 is the simplest, traditional, and important ferroelctric ceramics.…”
