Enhanced Photocatalytic Activity of BiVO4/Bi2S3/SnS2 Heterojunction under Visible Light

Abstract: Heterojunction photocatalysts have attracted a significant amount of attention due to their advantages over a single photocatalyst and, particularly, their superior spatial charge separation. Herein, the BiVO4/Bi2S3/SnS2 heterojunction was synthesized via solvothermal synthesis with different ratios of BiVO4 to SnS2. The photodegradation rate of the 0.03 BiVO4/SnS2 sample for rhodamine B removal is 2.3 times or 2.9 times greater than that of a single SnS2 or BiVO4, respectively. The chemical bond between photo… Show more

“…The photoelectrodegradation rate constant (k) was used to compare the degradation rate among various photocatalysts, assuming that the pseudo-first-order reaction model ln(Co/C) = kt. 62 As shown in Fig. 11c, the kinetic model fits well with the data of the pristine WO defects in S-doped ZnO can act as active centers to capture photoinduced electrons and inhibit recombination of photoinduced carriers.…”

“…Furthermore, the photoelectrocatalytic efficiencies of RhB solution for the pristine WO 3 , SW-1, SW-2, and SW-3 are evaluated to 48, 74, 87, and 67%, respectively, after 50 min irradiation. The photoelectrodegradation rate constant (k) was used to compare the degradation rate among various photocatalysts, assuming that the pseudo-first-order reaction model ln(Co/C) = kt 62. As shown in Fig.11c, the kinetic model fits well with the data of the pristine WO 3 and SW series samples.…”

“…As can be seen, the RhB degradation in all processes without Bi2S3 are almost neglected. It can be observed that only the light irradiation has no significant contribution for the degradation of RhB using Bi2S3 nanorods, which has already been reported [24]. Once the valence band maximum of Bi2S3 has no potential to oxidize water molecules to produce hydroxyl radical ( .…”
