Efficient Solar Light Harvesting CdS/Co9S8 Hollow Cubes for Z‐Scheme Photocatalytic Water Splitting

Abstract: Hollow structures with an efficient light harvesting and tunable interior component offer great advantages for constructing a Z‐scheme system. Controlled design of hollow cobalt sulfide (Co9S8) cubes embedded with cadmium sulfide quantum dots (QDs) is described, using hollow Co(OH)2 as the template and a one‐pot hydrothermal strategy. The hollow CdS/Co9S8 cubes utilize multiple reflections of light in the cubic structure to achieve enhanced photocatalytic activity. Importantly, the photoexcited charge carriers… Show more

“…The Z‐scheme largely relaxes the bandgap requirement of semiconductors, resulting in an expansion of candidates for various photocatalytic reactions. [20b,52] Very recently, the combination of Z‐scheme and hollow nanostructures composed of Co 9 S 8 and CdS was reported to achieve much better photocatalytic H 2 evolution performance compared with that of the solid counterpart (Figure c,d) . However, the mechanism understanding of the Z‐scheme system is still not fully understood and continuous efforts are required to achieve more efficient solar‐energy‐conversion systems.…”

“…Finally, the photocatalytic process occurs with the dye degradation or water molecules splitting on the surface of photocatalysts . So far, modifying traditional photocatalysts (e.g., TiO 2 , CdS, and BiWO 6 ) for enhanced activity or developing new type of photocatalysts (e.g., sulfides, oxides, and nitrides) have been regarded as two competitive strategies to meet the demand for solving energy and environmental problems. Among various new materials, layered Cu 2 MX 4 (M = Mo, W; X = S, Se), which is an important ternary transition metal chalcogenide (TTMC), has attracted much attention due to the outstanding properties with adjustable component, variable structure, diversified morphology, and unique electronic structure.…”
