Synthesis and photoluminescence of graphdiyne
Publication date: December 2018Source: New Carbon Materials, Volume 33, Issue 6Author(s): Yong-ping Zheng, Qian Feng, Nu-jiang Tang, You-wei DuAbstractGraphdiyne was prepared by a cross coupling reaction and characterized by SEM, TEM, XRD, Raman spectroscopy and XPS. Its photoluminescence (PL) properties were investigated. It was found that the graphdiyne has a thickness of ca. 1 μm, a O/C atomic ratio of ca. 0.1741 and many oxygen-containing functional groups. It exhibits strong ultraviolet (UV) PL at 397 nm and optical absorption at ca. 280 nm. It is proposed that the oxygen-containing functional groups in the graphdiyn...

Sulfidation of iron confined in nitrogen-doped carbon nanotubes to prepare novel anode materials for lithium ion batteries
Publication date: December 2018Source: New Carbon Materials, Volume 33, Issue 6Author(s): Xin Pan, Yang Liu, Xu-zhen Wang, Zong-bin Zhao, Jie-shan QiuAbstractThe performance of lithium ion batteries (LIBs) is highly dependent on the properties of the anode materials. Developing new carbon materials and metal oxides/sulfides with high capacities has attracted growing attention due to the limited theoretical capacity of commercial graphite. Pyrite (FeS2) is environmental benign, inexpensive and has a high theoretical capacity of 894 mAh g−1 because of its four-electron reduction by lithium, which make it promising for use ...

Nanofibers with MoS2 nanosheets encapsulated in carbon as a binder-free anode for superior lithium storage
Publication date: December 2018Source: New Carbon Materials, Volume 33, Issue 6Author(s): Xiu Zhang, Ya-kai Deng, Yan-li Wang, Liang Zhan, Shu-bin Yang, Yan SongAbstractOne-dimensional MoS2/carbon nanofibers (MoS2-CNFs) were synthesized by electrospinning using exfoliated MoS2 nanosheets and polyacrylonitrile as the precursors. The exfoliated MoS2 nanosheets about 150 nm across were encapsulated in carbon, and the free-standing MoS2/CNF film was easily cut into a flexible tablet that could be directly used as a binder-free anode for lithium storage. The MoS2/CNFs showed a high reversible capacity of 700 mAh g−1 at 100 mA...

Preparation of an activated carbon from hazelnut shells and its hybrids with magnetic NiFe2O4 nanoparticles
Publication date: December 2018Source: New Carbon Materials, Volume 33, Issue 6Author(s): Milad Jamal Livani, Mohsen Ghorbani, Hassan MehdipourAbstractA low cost activated carbon was prepared from hazelnut shells by chemical activation with sodium hydroxide at 600 °C in a N2 atmosphere and then combined with magnetic NiFe2O4 nanoparticles by hydrothermal and co-precipitation methods. Samples were characterized by FESEM, TEM, XRD, FT-IR, nitrogen adsorption and magnetic measurements. Results indicated that the NiFe2O4 nanoparticles synthesized by the hydrothermal method had a higher saturation magnetization and smaller ave...

Almost total desulfurization of high-sulfur petroleum coke by Na2CO3-promoted calcination combined with ultrasonic-assisted chemical oxidation
Publication date: December 2018Source: New Carbon Materials, Volume 33, Issue 6Author(s): Pu-jie Zhao, Cheng Ma, Ji-tong Wang, Wen-ming Qiao, Li-cheng LingAbstractA two-stage desulfurization method for high-sulfur petroleum coke was developed using Na2CO3-promoted calcination, followed by ultrasonic-assisted chemical oxidation. Using a Na2CO3 to coke mass ratio of 1:4 and an average particle size of 80 µm for the coke, the desulfurization efficiency of the coke reached a maximum of 67.2% using Na2CO3-promoted calcination at 900 °C for 2 h with a heating rate of 1°C /min. The total desulfurization after the subsequent ul...

Effects of the ultrasound-assisted H3PO4 impregnation of sawdust on the properties of activated carbons produced from it
Publication date: October 2018Source: New Carbon Materials, Volume 33, Issue 5Author(s): Zong-bo Zhang, Xiao-yang Liu, Da-wei Li, Tian-tian Gao, Yu-qi Lei, Bao-gui Wu, Jia-wei Zhao, Yan-kui Wang, Ling WeiAbstractThe effects of the ultrasound-assisted H3PO4 impregnation of sawdust on the pore structure, morphology, surface functional groups, and adsorption capacities for iodine and methylene blue of activated carbons produced from it were investigated. Results showed that ultrasonic impregnation promoted the mass transfer and uptake of H3PO4, which simultaneously increased specific surface area, pore volumes of micropores, ...
