Controlled formation of a flower-like CdWO₄–BiOCl–Bi₂WO₆ ternary hybrid photocatalyst with enhanced photocatalytic activity through one-pot hydrothermal reaction

Abstract

Flower-like CdWO4–BiOCl–Bi2WO6 ternary hybrid photocatalyst shows enhanced photocatalytic activity due to dye sensitization and its cascade structure.

Direct electrospinning method for the construction of Z-scheme TiO2/g-C3N4/RGO ternary heterojunction photocatalysts with remarkably ameliorated photocatalytic performance

“…As demonstrated previously, ternary photocatalysts comprising TiO2, g-C3N4, and RGO have demonstrated the best photocatalytic activity in comparison with binary and single-component photocatalysts [47][48][49][50][51]. For example, Zhang et al [47] have successfully fabricated g-C3N4 and TiO2 co-hybridized three-dimensional graphene aerogel composites using the hydrothermal approach coupled with freeze drying; this process comprises the preparation of C3N4 and graphene oxide, a hydrothermal process at 180 °C for 24 h, further hydrothermal treatment in ammonia solution at 120 °C for 3 h, and subsequent freeze drying.…”

Bi2WO6–BiOCl heterostructure with enhanced photocatalytic activity for efficient degradation of oxytetracycline

“…As one of the simplest Aurivillius phases, bismuth tungstate (Bi 2 WO 6 ) has received a lot of attention due to its special chemistry structure and excellent visible-light response properties 17 – 19 . Bi 2 WO 6 has suitable band edges (E CB = 0.03 eV, E VB = 2.93 eV) 20 , and can match well with BiOCl (E CB = − 0.80 eV, E VB = 1.09 eV) to form a heterostructure 13 .…”
