Selective Ferroelectric BiOI/Bi4Ti3O12 Heterostructures for Visible Light-Driven Photocatalysis

Abstract: Ferroelectric-photocatalyst/photocatalyst heterojunctions have very attractive photocatalytic activities. Besides enhanced charge-carrier separation due to their internal electric fields, charge transfer could be even further enhanced by designing the heterojunction interface. In this work, the polarization–adsorption interaction that exists in ferroelectric materials was employed for successful deposition of BiOI on specific surfaces of Bi4Ti3O12 plates in the dark at room temperature, where the positively po… Show more

“…Recently, Bi 4 Ti 3 O 12 has been modified by doping with different metals (Cr, Fe, and V) as well as coupling with low band gap semiconductor materials (MoS 2 , CuS, BiOI, g‐C 3 N 4 , BiOBr and Bi 2 S 3 ) to improve its optical and photocatalytic activity. The modified analogues of Bi 4 Ti 3 O 12 have been studied as photocatalyst for degradation of industrial dyes, pharmaceutical contaminants and hydrogen evolution reaction …”

“…[ 38 ] Moreover, dangling bond free surfaces of 2D materials also enable the flexible construction of vdW heterostructures through vdW integration, [ 39,40 ] providing promising material platforms for developing new devices with advanced functions. [ 41–65 ] From the point of device application, band alignment between semiconductors is the key that dominates the device performances. [ 66–68 ] For example, both holes and electrons in type‐I heterostructures tend to transfer to the components with narrow bandgap, and the high efficient recombining rate originating from the fine carrier confinement further enables the light‐emitting applications.…”

“…For the sake of increasing the photocatalytic performance of BiOI, measures should be taken to decrease the recombination of photogenerated carriers and improving its reduction and oxidation ability. So far, many measures have been taken to enhance the photocatalytic performance of BiOI, such as regulating morphology [13][14][15][16], exposing special crystal face [17][18][19], doping [20][21][22][23], compositing with other semiconductor [24][25][26][27] and synthesizing other bismuth oxyiodides such as Bi 4 O 5 I 2 [12,28], Bi 5 O 7 I [29][30][31] and Bi 7 O 9 I 3 [32,33].…”
