Bi₂Fe₄O₉@ZnIn₂S₄ S-scheme laminated heterojunction photocatalyst towards optimized photocatalytic performance

Abstract

Bi2Fe4O9@ZnIn2S4 laminated heterojunction photocatalysts exhibit excellent photocatalytic performance, which is ascribed to the formation of S-scheme laminated heterojunctions and strong 2D/2D laminated interface interactions.

[116,117] Bi 2 MO 6 dominates Bi-containing multi-metal oxides because of its facile preparation, suitable band gap, strong oxidation ability, and physicochemical stability.…”

“…They have layered Aurivillius structures in which [Bi 2 O 2 ] 2+ layers are intercalated with metal oxide layers. To date, numerous Bi‐containing multi‐metal oxides are applied to fabricate S‐scheme heterojunctions, such as Bi 2 M O 6 ( M = W, Mo), [ 109–111 ] BiVO 4 , [ 112,113 ] Bi 3 NbO 7 , [ 114 ] Bi 2 Fe 4 O 9 , [ 115 ] Bi 4 Ti 3 O 12 , [ 87 ] and Bi m +1 Fe m −3 Ti 3 O 3 m +3 ( m = 4, 5, 6). [ 116,117 ] Bi 2 MO 6 dominates Bi‐containing multi‐metal oxides because of its facile preparation, suitable band gap, strong oxidation ability, and physicochemical stability.…”
