MoS2@In2S3/Bi2S3 Core-shell dual Z-scheme tandem heterojunctions with Broad-spectrum response and enhanced Photothermal-photocatalytic performance

Hollow Nanoboxes Cu2‐xS@ZnIn2S4 Core‐Shell S‐Scheme Heterojunction with Broad‐Spectrum Response and Enhanced Photothermal‐Photocatalytic Performance

“…[11] Metal sulfides are key research hotspots among photocatalysts and have been widely exploited in many photocatalytic processes. [12][13][14] ZnIn 2 S 4 is a ternary metal-sulfide semiconductor that has been extensively studied by scientists due to its appropriate band gap (2.34-2.48 eV), excellent redox potential, and chemical stability for the reaction. [15][16][17] However, due to its inefficient photogenerated charge separation and low transferability, poor photoreduction ability, and low activity due to the quick complexation of photogenerated electrons and holes, the single ZnIn 2 S 4 still limits its use in photocatalysis.…”

Core–Shell Nanophotocatalysts: Review of Materials and Applications

“…This double-layered shell structure displayed enhanced PCA and stability compared to its individual-comprising materials and the single@single CS of ZnO@CdS . Additionally, MoS 2 @In 2 S 3 /Bi 2 S 3 core–dual-shell photocatalysts have been prepared via two hydrothermal steps endowed with enhanced stability and improved activity because of an enhanced interface area to offer suitable reactive locations for the reactants; the H 2 evolution and degradation efficiency with these CS nanocatalysts was almost 10 times greater than that of the original MoS 2 . Chen et al prepared a dual bimetallic CS material from Au–copper (Cu)@CeO 2 , which was assessed for the oxidation of benzyl alcohol; a composite with Au 1 Cu 9 @CeO 2 structure displayed the best activity, stability, and selectivity because of the effectual metal–support and metal–metal interaction in the structure among a variety of components and pristine materials.…”

The addition of Cu in the core is the key step to increase the activity because the creation of a Au−Cu alloy offered enhanced surface area, besides the generation of oxygen vacancies boosting the visible-light absorbance and the generation of new midlevel energy in association with CeO 2 acting as a trap, which leads to the promotion of charge transfer.…”

Na-doped g-C3N4/NiO 2D/2D laminated p–n heterojunction nanosheets toward optimized photocatalytic performance

“…3,4 More and more photocatalysts have been studied and applied, and the most studied are TiO 2 , [5][6][7] ZnO, 8-10 WO 3 , 11,12 etc., whose band gaps are ∼3.2, 3.4, and 3.2 eV, respectively, but their wide bandgap limits their photocatalytic applications. Materials such as CDs, 13 SnS 2 , 14,15 and Ni 2 P 16 possess narrow band gaps of ∼2.4, 1.7, and 1.0 eV, respectively, but they are volatile and toxic. Therefore, safe photocatalytic materials with suitable bandgap structures have become a hot research topic.…”
