Green synthesis of 3D core–shell SnS2/SnS-Cd0.5Zn0.5S multi-heterojunction for efficient photocatalytic H2 evolution

“…1b, the main peaks of SnS 2 located at 14.98°, 28.30°, 32.20°, 41.99°, 50.10°, 52.62°, and 55.14° are assigned to (001), (100), (011), (012), (110), (111), and (103) facets, respectively, which indicated the hexagonal SnS 2 phase (JCPDS: 83-1705). 34,37 In the SS composite, except for the major characteristic peaks of SnS 2 , the diffraction peaks at 21.99°, 26.00°, 27.48°, 30.48°, 31.53°, 39.07°, and 42.49° are ascribed to (011), (012), (102), (110), (111), (113), and (021) crystal facets, respectively, matching with the orthorhombic SnS phase (JCPDS: 75-0925). 38 The co-presence of Sn 2+ and Sn 4+ in the SnS 2 –SnS (SS) composite is attributed to the oxidation of the Sn 2+ precursor to Sn 4+ during the preparation process.…”

“…36 In the above applications, the introduction of SnS 2 /SnS significantly improved the performance. 37 Inspired by the above results, we consider introducing SnS 2 /SnS into the CZS twin crystal to evaluate the photocatalytic hydrogen evolution performance under visible light irradiation.…”

Covalent Bond Hybrid Nanostructure of N-doped rGO and Ultrathin SnS2 with High Porosity for Lithium-Ion Batteries

“…48 There was no significant change in the grain size (Table S1) of SnS 2 after removing the PMMA template. The characteristics of Raman (Figure 2c) illustrated that the vibration of 310 cm −1 was the A 1g mode of fewer layer SnS 2 , and the adsorption peaks of 1342 and 1580 cm −1 belong to the D and G bands of graphene, 30,49 respectively. It is noteworthy that the intensity ratio I D /I G (∼1.24) of SnS 2 @ NRGO-3 is significantly higher than that of others (Table S2).…”

“…In recent years, the group IV elements, metal oxides, and metal sulfides have greatly attracted the interest of lithium-ion, − sodium-ion, and potassium-ion , battery researchers. Transition metal sulfides are the most promising anode electrode materials to replace graphite anodes for higher capacity through reversible desorption/intercalation with lithium ions by conversion and alloying. − The large interlayer spacing (0.59 nm) of two-dimensional layer material tin sulfide (SnS 2 ) provides a well-resistant carrier space that can accelerate the diffusion of lithium-ion to some extent. − However, the pure SnS 2 electrodes have poor electrical conductivity, and high volume change rates during the charging and discharging, leading to severe electrode fragmentation. − Therefore, the lithium storage performance of realistic SnS 2 is poor. Carbon materials play an important role in Li + batteries, not only as direct electrode materials but also as active materials loaded in the conductive networks and electrochemical reaction frameworks. , To solve the problem of volume expansion, hybrid carbon/noncarbon structures have been extensively investigated, including hierarchical structures, core–shell structures, , sandwich structures, nanoarray structures, and carbon cage structures .…”

Optimization Strategies Toward Functional Sodium‐Ion Batteries

“…The electronic/ionic conductivity of the SnS-SnS 2 @GO anode is increased due to the unique internal electric field in heterostructured SnS-SnS 2 p-n junctions and the GO modification. [72] Wang et al prepared Mxene-MoS 2 heterostructure by calcinating Mo, S source, and PVP-modified Mxene at 750 °C in an inert atmosphere. The MoS 2 nanosheets are anchored to the accordion-like Mxene with unique open interlayer.…”
