A multi‐nuclear copper sulfide CuxSy with micro‐snowflake structure derived from a known four‐core copper cluster C28H36Cl6Cu4N4O5 was fabricated by hydrothermal method in mild condition. The growing process of the snowflake structure experienced from particles, to sheets and flowers, which depended on the reaction time. The prepared materials of high‐nuclear copper sulfide in different shapes were taken as catalysts for methylene blue and rhodamine B degradation. The degradation degree of the methylene blue reached up to 97.7% after 13 minutes and it needed 16 minutes for that of the rhodamine B up to 98.2%, which demonstrated that the snowflakes‐like CuxSy exhibited excellent photo‐catalytic property. Moreover, the high stability of the catalysts was confirmed by cycle experiments and SEM images.

“…For example, polyaniline (PAN)-CuS hierarchical heterostructures are synthesized in situ on PAN fibers prepared by electrospinning through a simple hydrothermal sulfuration growth process, exhibiting a "flowering branches" morphology. [71] Zhang et al synthesized flexible indium-doped tin oxide (ITO)/CuS nanosheet network films by combining the electrospinning and sputtering techniques (Figure 7e). [72]…”

extensive interest, [1][2][3] such as SCs, [4] rechargeable ion batteries, [5] water splitting, [6] metal-air batteries, [7] and CO 2 RR. [8] However, the practical applications of SCs and rechargeable ion batteries are limited by low energy density and low power density, respectively. [9,10] The multiple-electron transfer reactions in water splitting have posed a significant challenge that limits the catalytic efficiency and cycle stability. [11] At present, the urgent issue of metal-air battery is to design high-performance bifunctional electrodes. [12] For CO 2 RR, the technical realization is limited by the activity and selectivity of the catalyst, and the selectivity of its product beyond that of CO. [13,14] In these electrochemical devices, electrodes represent the core component, which dictates the efficiency, energy and power density, as well as catalytic activity and durability.Since the birth of graphene, 2D materials have attracted great attention due to their unique electrochemical, mechanical, and optical properties and diverse applications, as manifested in over 3000 academic papers each year. [15,16] 2D materials possess some structural advantages over the 0D and 1D counterparts by interlayer gap bonding and weak out-of-plane Van der Waals interaction, which provides an interesting platform for energy storage and conversion research. [17,18] So far, the 2D material family mainly includes transition metal dichalcogenides, transition metal carbides, layered metal oxides, layered double hydroxides and other graphene-like materials, such as black phosphorus. Of these, copper-based materials have received extensive attention because of high natural abundance, low price, high strength, arc erosion resistance, easy preparation of various nanoshapes, wear resistance, etc. (Figure 1), [19,20] leading to excellent electrochemical performance and advancement of electrochemical energy storage and conversion (Figure 2). For example, with a large surface area and potential size effect, CuO nanostructures, a p-type semiconductor, have excellent physical and chemical properties for SCs, as well as interesting magnetic and superhydrophobic properties, as compared with other metal oxides, such as TiO 2 , ZnO, WO 3 , and SnO 2 . [21] Cu-S compounds are a promising lithium cathode with a high energy density and long cycling stability. [22] Cu-Se is also considered as a novel cathode 2D materials have shown great potential as electrode materials that determine the performance of a range of electrochemical energy technologies. Among these, 2D copper-based materials, such as Cu-O, Cu-S, Cu-Se, Cu-N, and Cu-P, have attracted tremendous research interest, because of the combination of remarkable properties, such as low cost, excellent chemical stability, facile fabrication, and significant electrochemical properties. Herein, the recent advances in the emerging 2D copper-based materials are summarized. A brief summary of the crystal structures and synthetic methods is started, and innovative strategies for improving electro...

“…For example, hierarchical 3D CuS structures have been prepared as efficient Fenton-like reagents for dye decolorization. 151,152 Our group has demonstrated that CuS nanoparticles can be decorated on the surface of electrospun PAN nanofibers via a hydrothermal reaction. 151 Owing to the small sized CuS nanoparticles, porous and freestanding characteristic of the CuS/PAN nanofibers membrane, they show a good Fenton-like property, which can catalytically degrade methylene blue (MB) in the presence of H 2 O 2 efficiently.…”
