Fe-MOF-Derived Efficient ORR/OER Bifunctional Electrocatalyst for Rechargeable Zinc-Air Batteries.
Yun-Wu Li,Wen-Jie Zhang,Jing Li,Huiyan Ma,Hong-Mei Du,Dacheng Li,Suna Wang,Jinsheng Zhao,Jianmin Dou,Liqiang Xu +9 more
TL;DR: The efficient ORR/OER bifunctional electrocatalytic activity and long-term durability of the obtained composite might be attributed to the characteristic honeycomb-like porous structure with sufficient accessible active sites, the synergistic effect of FeS and Fe3C, and the N,S co-doped porous carbon, which provides a promising application potential for portable electronic Zn-air battery related devices.

Robust Interface Ru Centers for High-Performance Acidic Oxygen Evolution.
Xiaoju Cui,Xiaoju Cui,Pengju Ren,Chao Ma,Jia Zhao,Ruixue Chen,Ruixue Chen,Shiming Chen,N. Pethan Rajan,Haobo Li,Liang Yu,Zhong-Qun Tian,Dehui Deng,Dehui Deng +13 more
TL;DR: Density functional theory (DFT) calculations reveal that the interface Ru centers between theRuO2 and the graphene can break the classic scaling relationships between the free energies of HOO* and HO* to reduce the limiting potential, rendering an enhancement in the intrinsic OER activity and the resistance to over-oxidation and corrosion for RuO2.
