“…In the photocatalytic process, high specic surface areas can directly affect the photoactivities and adsorption abilities of the photocatalysts. 59,60 As shown in Fig. 6a, when Fig.…”

Reusable, Free‐Standing MoS2/rGO/Cu2O Ternary Composite Films for Fast and Highly Efficient Sunlight Driven Photocatalytic Degradation

“…The rate constant of MB dye degradation for ternary photocatalyst film (k=4.18) is greater than pure MoS 2 (k=2.18) and MoS 2 /rGO (k=2.88) photocatalysts which indicates the ternary film exhibits rapid degradation rate. The adsorption of MB dye molecules over Cu +1 sites is stronger and addition of rGO enhances the charge transfer rate due to synergistic effect of ternary composite structure with its π‐conjugated structure, which in turn reduces the recombination rate of photogenerated charge carriers . Furthermore, the stability and reusability are key factors for photocatalysts.…”

Facile Synthesis of Heterojunctioned ZnO/Bi2S3 Nanocomposites for Enhanced Photocatalytic Reduction of Aqueous Cr(VI) under Visible-Light Irradiation

“…Furthermore, it could be seen that some tiny nanocrystals marked by a red circle in Figure 3a were conglutinated tightly to the nanosheets. Figure 3b exhibits a lattice image from the (100) planes with the interplaner spacing d (100) = 0.280 nm of ZnO [33] and that from the (130) planes with the interplaner spacing d (130) = 0.360 nm of Bi 2 S 3 [34]. Moreover, intimate interface was clearly detected in Figure 3b and the heterojunction was somewhat preferably formed during the solvothermal fabrication of the 5%-ZnO/Bi 2 S 3 composite [35,36].…”
