Preparation and electrochemical properties of CoS2/carbon nanofiber composites

Sulfonic acid functionalized dendrimer-grafted cellulose as a solid acid catalyst for the high-yield and green production of 5-hydroxymethylfurfural

“…The deconvoluted C 1s spectrum confirms the presence of C–C/C–H, C–S, C–O/C–N, C–O–C, and CO at binding energies of 284.7, 285.8, 286.6, 287.4, and 288.2 eV, respectively. 36,37 In the case of O 1s, the peaks located at binding energies of 531.2, 532.1, 532.6, and 533.3 eV can be assigned to S–OH, SO, CO, and C–O–H/C–O–C, respectively. 36,38 The deconvoluted N 1s spectrum exhibits a peak with binding energy of 398.9 eV, which can be attributed to C–N–C.…”

Hollow CoS2 anchored on hierarchically porous carbon derived from Pien Tze Huang for high-performance supercapacitors

“…The microstructure, surface information, and defects degree of the materials were characterized by X-ray photoelectron spectroscopy (XPS, Thermo Scientific K-Alpha), Fourier transform infrared spectroscopy (FTIR, Nicolet is 10), and Raman spectroscopy (LabRam HR Evolution). [26][27][28] The Brunauer-Emmett-Teller method (BET, Gemini 2390 ISN#626) was used to characterize the specific surface area and porosity. Thermal decomposition behavior was analyzed using a Thermogravimetric Analyzer (TGA, Netsch TG209F1) at a temperature ranging from 30 to 800 °C with a heating rate of 10 °C min −1 .…”
