In situ sol-gel synthesis of ultrafine ZnO nanocrystals anchored on graphene as anode material for lithium-ion batteries

Li, Haipeng; Wei, Yaqiong; Zhang, Yongguang; Zhang, Chengwei; Wang, Gongkai; Zhao, Yan; Yin, Fuxing; Bakenov, Zhumabay (Ceramics International, 2016-08-01)

Abstract Ultrafine ZnO nanocrystals anchored on graphene were synthesized by a facile and highly efficient in situ sol-gel method. Uniform ZnO nanocrystals with an average size of 9.3nm were well dispersed on graphene ...
Simple One-Pot Synthesis of Hexagonal ZnO Nanoplates as Anode Material for Lithium-Ion Batteries

Li, Haipeng; Wei, Yaqiong; Zhao, Yan; Zhang, Yongguang; Yin, Fuxing; Zhang, Chengwei; Bakenov, Zhumabay (Copyright © 2016 Haipeng Li et al., 2015-12-15)

Hexagonal ZnO nanoplates were synthesized via simple one-pot hydrothermal reaction of Zn(CH3COO)2 and CO(NH2)2. XRD, SEM, and HRTEM were used to investigate the composition and microstructure of the material. Together with ...
