Three-dimensional CuS hierarchical architectures as recyclable catalysts for dye decolorization

Abstract: In the current paper, we report the synthesis of three-dimensional (3D) copper sulfide (CuS) with novel tertiary hierarchical architectures prepared by a one-step solvothermal method through the reaction of sulfur powder and solid copper for the first time. In this work, porous copper foam is used as the template. In this material, the primary structure is the multi-structure interchange copper foam precursor, the secondary structure is 10-20 mm cubic solids, and the tertiary structure is interpenetrating flak… Show more

“…Compared to the MB + RhB degradation over the Au/InBi-3D sample, MB showed a better adsorptivity on the InBi-3D sample in the dark but a slower degradation after irradiation; no substantial adsorption or degradation of RhB appeared over the two photocatalysts. Taking into consideration of the two blank tests (without a photocatalyst and/or H 2 O 2 ), one can realize the importance of light and H 2 O 2 in the heterogeneous Fenton reaction [36], because the former could produce e -/h + pairs [24] and the latter could react with the photogenerated e -to yield highly reactive hydroxyl radicals that oxidize dye molecules into inorganic products (e.g., CO 2 , H 2 O, NO 3 − , NH 3 or N 2 ) [24,25]. Among all of the as-prepared samples, the 0.08 wt% Au/InBi-3D sample possessed the strongest mineralization ability for MB or RhB.…”

“…In the meanwhile, loading a trace amount of nanoscale noble metals could undoubtedly enable the 3DOM architecture to capture and transform light energy more effectively due to their plasmonic behaviors. As important industrial dyes that are resistant to biodegradation and direct photolysis, MB or RhB is the most used model pollutant [24][25][26][27]. Hence, we evaluate photocatalytic activities of xM/InBi-3D for the degradation of RhB, MB and RhB + MB.…”

“…These distinguishing features could be expected to be more advantageous rather than those of the powder samples, matching well with the principles of a highly efficient catalyst designs. [8][9][10][11] The hollow and 3D superstructures with different building blocks can be successfully synthesized by precisely controlling the nucleation and growth via a ''bottom-up'' selfassembly route. Many recent efforts have been employed to the synthesis of hollow architectures; however, most of the synthesized hollow architectures are spherical shaped and having polycrystalline shells.…”
