BaTiO3 nanocubes/cuboids with selectively deposited Ag nanoparticles: Efficient piezocatalytic degradation and mechanism

Strain-Driven Polarized Electric Field-Promoted Photocatalytic Activity in Borate-Based CsCdBO3 Bulk Materials

“…To verify that the high stirring speed and the clockwise direction have a high impact on the degradation of the organic pollutant, we further choose the TC as the target molecule to confirm the above phenomenon. From Figure c, we can clearly observe that the material shows an enhanced photocatalytic activity and a degradation efficiency of 92% can be reached in 30 min and this value is higher than most of the results reported in the literature studies − in Table . The photocatalytic TC decomposition rates for CCBO are 7.71, 7.81, 7.87, and 8.05 × 10 –3 min –1 under different rotations of 200, 400, 600, and 800 rpm, respectively (Figure d).…”

Effect of ferroelectric polarization on piezo/photocatalysis in Ag nanoparticles loaded 0.5(Ba0.7Ca0.3)TiO3–0.5Ba(Zr0.1Ti0.9)O3 composites towards the degradation of organic pollutants

“…[38][39][40] The surface charge generated during the piezoelectric effect can be retained for more extended and finally participate in catalysis reactions. These piezocatalysis reactions can be described as follows 41 :…”

Study of Corrosion Mechanisms in Corrosive Media and Their Influence on the Absorption Capacity of Fe2O3/NdFeO3 Nanocomposites

“…In this regard, much attention has been paid in recent years to studies aimed at a comprehensive study of the resistance of nanostructures to degradation mechanisms and corrosion processes occurring in nanomaterials [11,12]. A number of studies have shown that the degradation of nanostructures in conditions of aggressive media proceeds according to the mechanisms of pitting corrosion with the formation of ulcerous inclusions or growths leading to partial destruction of nanostructures [13][14][15].…”
