The construction of type II heterojunction of Bi2WO6/BiOBr photocatalyst with improved photocatalytic performance

Water-driven boost in the visible light photocatalytic performance of Cs2AgBiBr6 double perovskite nanocrystals

“…[33][34][35] As is known, BiOBr can also show excellent photocatalytic performance in both the ultraviolet and visible regions. [36][37][38][39] If there is a heterojunction formed between Cs 2 AgBiBr 6 and BiOBr, the photocatalytic performance of Cs 2 -AgBiBr 6 may be boosted in a water-involved system, thus providing feasibility for the application of Bi-based perovskites in water. But corresponding research is currently lacking.…”

Ultrafast conversion of carcinogenic 4-nitrophenol into 4-aminophenol in the dark catalyzed by surface interaction on BiPO4/g-C3N4 nanostructures in the presence of NaBH4

“…In recent decades, the scientic community has addressed widely the application of bismuth based nanomaterials such as BiOBr, Bi 2 S 3 , BiPO 4 , BiVO 4 , Bi 2 WO 6 , Bi 2 O 2 CO 3 in different catalytic applications thanks to their appropriate physicochemical and photonic characteristics. [31][32][33][34][35][36] In particular, BiPO 4 as a new bismuth salt catalyst, which has been developed for the rst type by Zhu's group, has been revealed as promising candidate in semiconductor catalysis due to its highly photocatalytic efficiency under UV light which was found to be superior that TiO 2 (P25, Degussa) towards the oxidation of dyes. 37 However, the catalytic performance of BiPO 4 has been greatly restricted.…”

Photoreduction properties of novel Z-scheme structured Sr0.8La0.2(Ti1−δ4+Tiδ3+)O3/Bi2MoO6 composites for the removal of Cr(vi)

“… αhν = A ( hν − E g ) n /2 where α is the absorption coefficient, h is the Planck's constant, ν is the light frequency, A is the absorption coefficient, and n represents 1 or 4 for direct or indirect band gap SMs. 51 The intersection of the tangent with the x -axis of Tauc plots (Fig. S5(b) and (c) † ) can give a good approximation of E g values ( Table 2 ) of the samples.…”
