“…I D and I G are the strengths of D peaks and G peaks, respectively. The larger the I D / I G value, the more defects in the material and the higher the degree of disorder. − The Raman spectra and I D / I G values of the samples can be obtained from Figure b. As the amount of H 2 O 2 added increases, the I D / I G of the obtained porous carbon materials gradually increases, indicating that adding more H 2 O 2 will result in more carbon lattice defects.…”

Biomass-based porous carbon has attracted much attention of researchers due to its wide range of raw materials, low cost, and other advantages. It has been also widely used in energy storage devices such as lithium-ion batteries. The carbonization process and final morphology of biomass are indirectly affected by the surface modification and structure optimization of the original biomass. The focus of this study is to prepare porous carbon, which can be used as an electrode material of a lithium-ion battery by surface modification and structure regulation of biomass pretreatment. In this study, the method of H2O2-assisted hydrothermal treatment was used to prepare a kind of bagasse based porous carbon materials that can be used in lithium-ion batteries. The reaction process of H2O2 and bagasse under hydrothermal conditions was explored and described. The results showed that H2O2 promoted the hydrolysis and oxidation of lignocellulose in bagasse and the small molecules obtained from lignocellulose hydrolysis under hydrothermal conditions would be repolymerized to form carbon spheres. The prepared carbon material was applied to the lithium-ion battery. Under a current density of 0.1 A g–1, the specific capacity of 891 mAh g–1 in the first cycle was displayed, and a specific capacity of 453 mAh g–1 was maintained after 150 cycles. At the same time, it showed a good rate performance. After 10 cycles at current densities of 0.1, 0.2, 0.5, 1, 2, and 5 A g–1, the specific capacities of 545, 421, 307, 245, 195, and 133 mAh g–1 were obtained. All the raw materials and products used in this experiment are harmless to the environment, which has certain guiding significance for the structural regulation and green synthesis of lignocellulosic biomass-derived carbon materials.

A new ternary composite of 1T‐molybdenum disulfide, hexagonal tungsten trioxide, and reduced graphene oxide (M‐W‐rGO) is synthesized by using a one‐pot hydrothermal process. The synergetic effect of 1T‐MoS2 and hexa‐WO3 nanoflowers improves the electrochemical performance for supercapacitors by inducing additional active sites and hexagonal tunnels, respectively, which lead to high storage capacity and easy transfer of electrolyte ions. The ternary M‐W‐rGO composite has a high specific capacitance of 836 F g−1 at 1 A g−1, which is nearly twice that of binary composites of M‐rGO and W‐rGO with high capacitance retention of 86.35 % after 3000 cycles at a high current density of 5 A g−1. This study provides a new ternary composite that can be used as an electrode material for high‐performance supercapacitors.

Abstract. Compared with the traditional materials, carbon materials exhibit excellent physical, electrical, mechanical and chemical properties. Porous carbon is one of the structured carbon materials, with controlled large surface area, high surface activity, low density, superior chemicals, corrosion resistance and uniform pore features on micrometer and nanometer scales. It is explored as advanced material in lithium-ion batteries, Super capacitor, fuel cell, energy storage and conversion devices, and adsorption materials, because of its excellent property. The characterization methods were the traditional instruments, such as transmission electron microscopy, scanning electron microscopy, Raman spectrum, X-ray diffraction, X-ray photoelectron spectroscopy and infrared spectroscopy. This article demonstrated new method to character the porous carbon with coherent anti-stokes Raman microscopy.
