Piezoelectric BaTiO3 with the milling treatment for highly efficient piezocatalysis under vibration

Remarkable Pyro-Catalysis of g-C3N4 Nanosheets for Dye Decoloration under Room-Temperature Cold–Hot Cycle Excitation

“…The pseudo first-order kinetics of RhB dye decoloration in the presence of 2D organic g-C 3 N 4 nanosheets is confirmed by making a linear plot of ln( C 0 / C ) vs. the cold–hot thermal cycle times, as shown in Figure 5 b. The kinetic equation can be expressed as the following Equation (2) [ 34 , 35 ], ln( C / C 0 ) = − k · t where t and k represent different cold–hot cycle times and the rate constant determined from the minus slope of ln( C 0 / C ) vs. the cold–hot cycle times, respectively. The rate constant of g-C 3 N 4 is determined from Equation (2) to be ~6.5 × 10 −2 time −1 , confirming the pseudo first-order kinetic characterization of RhB decoloration in the presence of 2D organic g-C 3 N 4 nanosheet catalyst.…”

Strongly enhanced piezocatalysis of BiFeO3/ZnO heterostructure nanomaterials

“…found that Ba(Zr 0.05 Ti 0.95 )O 3 particles synthesized through a conventional solid state method can degrade 65% Methyl Orange (MO) dye after being vibrated for 100 min. 14 In the previous work of our group, it has been indicated that these numerous piezoelectric materials like ZnO, [15][16][17] BaTiO 3 , 10,18,19 and NaNbO 3 , 20,21 demonstrate an obvious piezocatalytic dye decomposition performance. How to make further enhancement in the piezocatalytic dye decomposition ratio is quite urgent work for practical application.…”

Electron/hole piezocatalysis in chemical reactions

“…The hydrothermally synthesized BaTiO 3 NFs were prepared by Yao et al (2022). 167 In brief, Na 2 Ti 3 O 7 was first synthesized hydrothermally in an autoclave with the precursor TiO 2 in a sodium hydroxide solution. H 2 Ti 3 O 7 , which was obtained after soaking Na 2 Ti 3 O 7 in an acidic solution, was dispersed in a solution of Ba(OH) 2 ·8H 2 O and heated in an autoclave at 210 °C to obtain BaTiO 3 NFs.…”
