Piezoelectric effect enhanced plasmonic photocatalysis in the Pt/BaTiO3 heterojunctions

Harnessing ultrasound in photocatalysis: Synthesis and piezo-enhanced effect: A review

“…The construction of heterojunctions is the primary strategy to improve the piezoelectric effect. For instance, Meng et al [60] fabricated a heterojunction of Pt/BaTiO 3 for piezoelectric enhanced photocatalysis, showing a 1.32-fold increase of methyl orange photodegradation than that under normal light conditions, which confirmed the enhancement of piezoelectric effects on the photocatalytic activity. Liu et al [61] fabricated BaTiO 3 @ReS 2 Schottky heterostructure to facilitate electron transport, demonstrating a 2.44 times higher activity than conventional photocatalysis.…”

Future perspectives in green hydrogen production by catalyzed sono-photolysis of water

“…Furthermore, electronic jumps occur in the VB and CB of those materials providing additional electron-hole source for the flowing separation and transport 104 . Meng et al 105 reporting a variation of 1,7% (Tab.4) when the photocatalyst was sulfur-doped. Applying the corrected Stoke formula for the volume viscosity, 3% variations of the acoustic property absorption of the solution was calculated (Tab.4).…”

“…101 Furthermore, electronic jumps occur in the VB and CB of these materials providing additional electron–hole sources for the flow separation and transport. 104 Meng et al 105 showed 1.32-fold increase of methyl orange photodegradation by Pt/BaTiO 3 heterojunction fabrication for piezoelectric enhanced photocatalysis, and Liu et al 106 demonstrated 2.44 times higher photocatalysis activity due to the presence of the BaTiO 3 @ReS 2 Schottky heterostructure. Hydrogen production by piezoelectric-assisted sono-photocatalysis was investigated with the g-C 3 N 4 photocatalyst with a 50% H 2 production rate improvement from water sonolysis (12.16 vs. 8 μmol (g −1 h −1 )) and SynEf ∼ 0.32.…”

Ag Nanoparticles Deposited onto BaTiO3 Aerogel for Highly Efficient Photodegradation

“…The deposition of noble metals is frequently employed to effectively tackle the critical issue of high recombination rates of photoinduced charged species (electrons and holes). The nanostructured metals can act as electron traps, leading to improvement in the separation of electrons and holes, and consequently enhancing photocatalytic activity [ 23 , 24 ]. Liu et al [ 15 ] successfully prepared the flower-like BaTiO 3 nanotube arrays (NTAs) by a hydrothermal method using TiO 2 NTAs as precursors.…”
