One-pot hydrothermal synthesis of reduced graphene oxide/carbon nanotube/α- Ni(OH)2 composites for high performance electrochemical supercapacitor
TL;DR: In this paper, the structural characterization of the composites by EDX, XRD, FT-IR, XPS, Raman, FESEM and TEM indicate that α-Ni(OH) 2 nanoparticles with the size around 5nm are randomly decorated onto three-dimensional (3D) hierarchical structure RGO/CNT.
Journal ArticleDOI

Wuxing Hua,Zhi Yang,Huagui Nie,Zhongyu Li,Jizhang Yang,Guo Zeqing,Ruan Chunping,Xi'an Chen,Shaoming Huang +8 more
TL;DR: This work introduced a concept involving the dithiothreitol (DTT) assisted scission of polysulfides into lithium-sulfur system, and found that employing this molecule scission principle offers a promising avenue to achieve high-performance lithium-Sulfur batteries.
Journal ArticleDOI
Sulfur-doped porous reduced graphene oxide hollow nanosphere frameworks as metal-free electrocatalysts for oxygen reduction reaction and as supercapacitor electrode materials
Xi'an Chen,Xi'an Chen,Xiaohua Chen,Xin Xu,Zhi Yang,Zheng Liu,Lijie Zhang,Xiangju Xu,Ying Chen,Shaoming Huang +9 more
TL;DR: The as-prepared S-PGHS has been demonstrated to be an efficient metal-free electrocatalyst for oxygen reduction reaction (ORR) with the activity comparable to that of commercial Pt/C and to be a supercapacitor electrode material with a high specific capacitance of 343 F g(-1), good rate capability and excellent cycling stability in aqueous electrolytes.
Journal ArticleDOI
Hydrothermal synthesis and photoluminescence properties of red phosphor BaSiF6:Mn4+ for LED applications
TL;DR: An efficient red phosphor, BaSiF6:Mn4+ free of manganese oxide impurities, has been synthesized by using a one-step hydrothermal method at 120 °C for 12 h as mentioned in this paper.
Journal ArticleDOI
The formation mechanism, improved photoluminescence and LED applications of red phosphor K2SiF6:Mn4+
TL;DR: In this paper, a red phosphor K2SiF6:Mn4+ has been prepared by etching of SiO2 in HF solution at a KMnO4 concentration as low as 0.08 mol L−1.
