Abstract

A scalable, green method to prepare microporous carbon from sugarcane waste for superior lithium storage capability of Fe1−xS.

A Ternary Fe1−xS@Porous Carbon Nanowires/Reduced Graphene Oxide Hybrid Film Electrode with Superior Volumetric and Gravimetric Capacities for Flexible Sodium Ion Batteries

“…The O element can be ascribed to the residual oxygen functional groups attached to the surface of rGO NSs. [32][33][34][35] The Fe 2p spectrum (Figure 3f) shows two peaks located at 708.9 and 721.4 eV, which can be ascribed to Fe 2p 3/2 and Fe 2p 1/2 of Fe 2+ , respectively. [31] The high-resolution S 2p spectrum (Figure 3e) can be fitted to four peaks located at 161.4, 162.6, 163.9, and 165.1 eV.…”

“…As shown in the C 1s spectrum (Figure 3d), CO (epoxy or alkoxy) and CO (carbonyl or carboxyl) groups have been identified and their low peak intensity confirms the successful reduction of GO. [16,27,[32][33][34][35] The first two peaks correspond to S 2− , whereas the other two centered at higher binding energy belong to S n 2− , both of which are characteristics of iron sulfides.…”

Carbonaceous Anodes Derived from Sugarcane Bagasse for Sodium‐Ion Batteries

“…[25][26][27] Biomass sourcess uch as peat moss, cotton,b anana peels, kelp, shaddock peels, pistachios, mangosteen shells, and cherry petals have been used to fabricate HCs. [36,37] SB is aw aste agricultural product of the sugar industry.I th as little economic value and is usually burned in open air,p roducing greenhouse gases and air pollution.I ti s highly desirable to transform this biowaste into ah igh-value functional carbon for battery anodes. Sugarcane is oneo ft he most abundant types of biomass.…”

Synthesis of FeS Nanoparticles Embedded in MoS2/C Nanosheets as High‐Performance Anode Material for Lithium‐Ion Batteries

“…Figure S1, Supporting Information shows the X‐ray diffraction (XRD) patterns of the as‐synthesized FeS@MoS 2 /C and FeS@C composites. For both the samples, the strong diffraction peaks are well matched with the crystal structure of FeS (PDF no 65‐3356), indicating that pure hexagonal FeS was synthesized and highly crystallized by this method . The strong diffraction peak of FeS@MoS 2 /C at about 14.2° refers to the (002) crystal plane of pure MoS 2 (PDF no 37‐1492) with a S—Mo—S‐layered structure .…”
