Journal ArticleDOI
Single Atomic Iron Catalysts for Oxygen Reduction in Acidic Media: Particle Size Control and Thermal Activation.
Hanguang Zhang,Sooyeon Hwang,Maoyu Wang,Zhenxing Feng,Stavros Karakalos,Langli Luo,Zhi Qiao,Xiaohong Xie,Chongmin Wang,Dong Su,Yuyan Shao,Gang Wu +11 more
TL;DR: A high-performance atomic Fe catalyst derived from chemically Fe-doped zeolitic imidazolate frameworks (ZIFs) by directly bonding Fe ions to imidAZolate ligands within 3D frameworks holds great promise as a replacement for Pt in future PEMFCs.
Journal ArticleDOI
3D porous graphitic nanocarbon for enhancing the performance and durability of Pt catalysts: a balance between graphitization and hierarchical porosity
Zhi Qiao,Sooyeon Hwang,Xing Li,Xing Li,Chenyu Wang,Widitha Samarakoon,Stavros Karakalos,Dongguo Li,Mengjie Chen,Yanghua He,Maoyu Wang,Zhenyu Liu,Guofeng Wang,Hua Zhou,Zhenxing Feng,Dong Su,Jacob S. Spendelow,Gang Wu +17 more
TL;DR: In this paper, a porous graphitic carbon (PGC) was used in a proton exchange membrane fuel cells (PEMFCs) to provide high porosity at multiple scales, which is favorable for uniform Pt nanoparticle dispersion and enhanced corrosion resistance.
Journal ArticleDOI
Mn- and N- doped carbon as promising catalysts for oxygen reduction reaction: Theoretical prediction and experimental validation
Kexi Liu,Zhi Qiao,Sooyeon Hwang,Zhenyu Liu,Hanguang Zhang,Dong Su,Hui Xu,Gang Wu,Guofeng Wang +8 more
TL;DR: In this paper, the authors combined computational and experimental studies to investigate the mechanism, activity, and durability of Mn and N co-doped carbon (denoted as Mn-N-C) as promising catalysts for oxygen reduction reaction (ORR) in challenging acid medium.
Journal ArticleDOI
Platinum-group-metal catalysts for proton exchange membrane fuel cells: From catalyst design to electrode structure optimization
TL;DR: In this article, a review of state-of-the-art Pt-based catalysts, carbon supports, proton conductive ionomers, and their structure effects are discussed.
Journal ArticleDOI
Atomically dispersed single iron sites for promoting Pt and Pt3Co fuel cell catalysts: performance and durability improvements
Zhi Qiao,Chenyu Wang,Chenzhao Li,Yachao Zeng,Sooyeon Hwang,Boyang Li,Stavros Karakalos,Jaehyung Park,A. Jeremy Kropf,Evan C. Wegener,Qing Gong,Hui Xu,Guofeng Wang,Deborah J. Myers,Jian Xie,Jacob S. Spendelow,Gang Wu +16 more
TL;DR: In this paper, an effective strategy to boost PGM catalysts through integrating PGM-free atomically-dispersed single metal active sites in the carbon support toward the cathode oxygen reduction reaction (ORR) was reported.
