Biaxially strained PtPb/Pt core/shell nanoplate boosts oxygen reduction catalysis
Lingzheng Bu,Nan Zhang,Shaojun Guo,Xu Zhang,Jing Li,Jianlin Yao,Tao Wu,Gang Lu,Jingyuan Ma,Dong Su,Xiaoqing Huang +10 more
TL;DR: A class of platinum-lead/platinum (PtPb/Pt) core/shell nanoplate catalysts that exhibit large biaxial strains appear to underlie the high endurance of these catalysts, which can undergo 50,000 voltage cycles with negligible activity decay and no apparent structure and composition changes.
Journal ArticleDOI
PdMo bimetallene for oxygen reduction catalysis
Mingchuan Luo,Zhonglong Zhao,Yelong Zhang,Yingjun Sun,Yi Xing,Fan Lv,Yang Yang,Xu Zhang,Sooyeon Hwang,Yingnan Qin,Jingyuan Ma,Fei Lin,Dong Su,Gang Lu,Shaojun Guo +14 more
TL;DR: PdMo bimetallene, a highly curved and sub-nanometre-thick nanosheet of a palladium–molybdenum alloy, is an efficient and stable electrocatalyst for the oxygen reduction and evolution reactions under alkaline conditions and is suggested that other metallene materials could show great promise in energy electrocatalysis.
Journal ArticleDOI
Co Nanoislands Rooted on Co-N-C Nanosheets as Efficient Oxygen Electrocatalyst for Zn-Air Batteries.
Peng Yu,Lei Wang,Fanfei Sun,Ying Xie,Xu Liu,Jingyuan Ma,Xiuwen Wang,Chungui Tian,Jinghong Li,Honggang Fu +9 more
TL;DR: The synthesis of Co nanoislands rooted on Co-N-C nanosheets supported by carbon felts (Co/Co-N/C) is reported, which leads to good bifuctional catalytic performances of Zn-air batteries.
Journal ArticleDOI
Synergistic Effects between Atomically Dispersed Fe−N−C and C−S−C for the Oxygen Reduction Reaction in Acidic Media
Hangjia Shen,Eduardo Gracia-Espino,Jingyuan Ma,Ketao Zang,Jun Luo,Le Wang,Sanshuang Gao,Xamxikamar Mamat,Guangzhi Hu,Guangzhi Hu,Thomas Wågberg,Shaojun Guo +11 more
TL;DR: This work has obtained a sulfur-doped Fe/N/C catalyst (denoted as Fe/SNC) that exhibits much better ORR activity than the sulfur-free variant (Fe/NC) in 0.5 m H2 SO4 in acidic solution.
Journal ArticleDOI
A Stable Bifunctional Catalyst for Rechargeable Zinc–Air Batteries: Iron–Cobalt Nanoparticles Embedded in a Nitrogen‐Doped 3D Carbon Matrix
TL;DR: A 3D catalyst, composed of nanoparticles of CoFe alloy embedded in N-doped carbon nanotubes tangled with reduced graphene oxide, was developed, which presents appreciable ORR/OER activity when applied in a Zn-air battery.
