“…Figure a shows the homogeneous morphology of NiCo 2 S 4 nanosheets, while the lattice stripe information on the typical (311) crystallographic planes of NiCo 2 S 4 nanosheets with a pitch of 0.271 nm can be observed by the high-resolution TEM (HRTEM) image in Figure b . Furthermore, the selected-area electron diffraction (SAED) image is illustrated in Figure c, clearly labeling the positions of the diffraction rings corresponding to the (311), (444), and (531) crystallographic planes of the NiCo 2 S 4 nanosheets. , Through the analysis of the elemental distribution of NiCo 2 S 4 nanosheets, the distribution of Ni, Co, and S elements can be precisely distinguished (as shown in Figure d–f). Further characterization was conducted by atomic force microscopy (AFM), as shown in Figure g,h.…”

Transition metal sulfides (TMS) exhibit unique attributes such as high electron mobility, excellent charge transfer ability, narrow band gap, and large surface area, which makes them particularly attractive for use in surface-enhanced Raman spectroscopy (SERS) and as catalysts applications. In this study, we prepared NiCo 2 S 4 TMS nanosheets through a hydrothermal process. These nanosheets display outstanding SERS activity, which is attributed to their exceptional charge transfer interactions with crystal violet (CV). In addition, NiCo 2 S 4 nanosheets display excellent laccase-like activity. Density functional theory (DFT) calculations further reveal that NiCo 2 S 4 −O 2 exhibits a low adsorption energy and pronounced laccase-like catalytic performance. Furthermore, the NiCo 2 S 4 nanosheets show great potential for the oxidation and detection of various catechin molecules. Consequently, the NiCo 2 S 4 nanosheets exhibit immense potential in various applications, including SERS analysis and detection, laccase-like antibacterial properties, and the degradation of environmental pollutants.

The traditional recycling methods of the spent lithium ion batteries (LIBs) involve the intricate and cumbersome steps. This work proposes a facile method of acid leaching followed by the sulfurization treatment to achieve the high Li leaching efficiency, and obtain high‐performance multi‐function electrocatalysts for oxygen reduction (ORR), oxygen evolution (OER), and methanol oxidation reactions (MOR) from the spent LIB ternary cathodes. By this method, the Li leaching efficiency from the spent LIB ternary cathode can reach 98.3%, and the transition metal sulfide heterostructures (LNMCO‐H‐450S) consisting MnS, NiS2, and NiCo2S4 phases can be obtained. LNMCO‐H‐450S shows the superior bifunctional oxygen catalytic activities with ORR half‐wave potential of 0.763 V and OER potential at 10 mA cm−2 of 1.561 V, surpassing most of the state‐of‐the‐art electrocatalysts. LNMCO‐H‐450S also demonstrates the superior MOR catalytic activity with the potential at 100 mA cm−2 being 1.37 V. Using LNMCO‐H‐450S as the oxygen catalyst, this work can construct the aqueous and solid‐state zinc‐air batteries with high power density of 309 and 257 mW cm−2, respectively. This work provides a promising strategy for the efficient recovery of Li, and reutilization of Ni, Co, and Mn from the spent LIB ternary cathodes.
