Coupling cobalt sulfide nanosheets with cadmium sulfide nanoparticles for highly efficient visible-light-driven photocatalysis

Constructing highly dispersed 0D Co3S4 quantum dots/2D g-C3N4 nanosheets nanocomposites for excellent photocatalytic performance

“…It can be observed that the metal products of Co belong to basic carbonates (Co(CO 3 )0.5(OH)Á0. [11,18,25,30]. No diffraction peaks of Co 3 S 4 among Co 3 S 4 /CNNS nanocomposites can be observed, which is due to the low load of Co 3 S 4 quantum dots and the relative low crystallinity [14,16].…”

“…Although some exciting results have been achieved, however, the agglomerated or large-sized cobalt sulfide nanoparticles significantly increase the migration distance of photogenerated carriers and reduce the reactive sites [20][21][22][23][24]. Furthermore, the irregular morphologies and random dispersion characteristics of cobalt sulfide result in the inability to fully utilize the 2D nanosheets of g-C 3 N 4 [25,26]. However, uniform 0D quantum dots have extremely small dimensions (<5 nm) and efficient photocarrier transport efficiency, besides, the tight interaction between 0D and 2D can improve the dispersion and stability of quantum dots [14,16,27,28].…”

Synthesis and characterization of mesoporous BiVO4 nanofibers with enhanced photocatalytic water oxidation performance

“…They found that most ZneCr LDHs exhibited photocatalytic activity. In addition, recent studies have confirmed that cobalt-based nanomaterials can reduce the activation energy, thereby can accelerate the reaction kinetics [26,27]. The synthesized Co x Ni 1−x LDHs, which have anisotropic morphology, were also applied as cocatalysts in water oxidation [28].…”

Selective Solid‐Liquid Interface Sulfidation Growth of Hierarchical Copper Sulfide and Its Hybrid Nanoflakes for Superior Lithium‐Ion Storage

“…Up to now, it is highly demanded yet remains challenging to develop a simple and facile strategy for production of high‐quality 2D metal sulfides in a controllable and scalable manner. On the other hand, regarding construction of hybrids, various co‐component and iso‐component metal sulfide hybrids have been successfully fabricated, including sheet Zn 0.76 Co 0.24 S, nanosheets of CdS/Co 3 S 4 , particle of Fe 3 O 4 @Cu 2‐x S and spherical Ni(OH) 2 @CuS, et al . While most of the co‐component metal sulfide hybrids could be fabricated within a single step and are 2D nanostructured, iso‐component metal sulfide hybrids relies on multi‐step synthesis in which the building blocks are constructed in‐sequence and hence usually resulted in hierarchical architectures.…”
