Facile Fabrication of Porous CuS Nanotubes Using Well-Aligned [Cu(tu)]Cl·1/2H₂O Nanowire Precursors as Self-Sacrificial Templates

Cobalt Sulfide/Graphene Composite Hydrogel as Electrode for High-Performance Pseudocapacitors

“…The peaks of CGH in the range 400–1000 cm −1 are in accord with pure CoS, confirming the presence of CoS in CGH. Moreover, the peaks at 536 and 628 cm −1 correspond to the vibrations of N-C-N and C = S in thiourea, while 453, 859, and 958 cm −1 correspond to N-C = S 28 29 . Compared to pure CoS, the slight shifts and broadening of these peaks indicated the possible formation of a covalent interaction after the in-situ deposition of CoS on graphene 30 .…”

Design and Synthesis of Cu@CuS Yolk–Shell Structures with Enhanced Photocatalytic Activity

“…In particular, copper sulfides (Cu x S with x = 1–2) are transition metal chalcogenides that have been found to be potentially useful materials for application in photocatalysis due to their low cost, high stability, and low cytotoxicity [ 7 ]. Recently, many varieties of copper sulfides micro-/nanostructures have been synthesized to improve their photocatalytic efficiency, including nanotubes [ 8 ], nanowires [ 9 ], nanorods [ 10 ], nanoplates [ 11 ], ball-flower [ 12 ], and hollow cages [ 13 ]. However, the photocatalytic activity of pure copper sulfides under visible light irradiation is not high enough for practical applications due to drawbacks associated with their narrow band gap, which results in the easy recombination of the photogenerated charges.…”

Surfactant free fabrication of copper sulphide (CuS–Cu 2 S) nanoparticles from single source precursor for photocatalytic applications

“…CuS (covellite) dispersed particles, Cu 7 S 4 -CuS hexagonal plates, Cu 9 S 5 (Digenite) octahedron, and Cu 2 S (chalcocite). In recent years CuS has been synthesized with different morphologies such as nanotubes [2], nanowires [3], nano plates [4], nano rods [5], ball-flower [6], nanoparticles [7], hollow cages [8] and hollow sphere [9] with biological sulphate reduction [10], chemical route [11], chemical vapour deposition [12], chemical vapour reaction (CVR) [13], hydrothermal method [3], electrospinning [14], sono-chemical method [15], solid state synthesis [16], liquid precipitation route [17], liquid-liquid interface [18], pressure leaching process [19], micro-emulsions [20] and self-sacrificial templates [21]. Covellite (CuS) proved to be a very fruitful nanomaterial for solar cell applications [22], photocatalytic degradation of dyes [23], as a cathode material in lithium ion rechargeable secondary batteries [24], gas sensing [25] etc.…”
