Journal ArticleDOI
Thermally Driven Structure and Performance Evolution of Atomically Dispersed FeN4 Sites for Oxygen Reduction
Jiazhan Li,Jiazhan Li,Hanguang Zhang,Widitha Samarakoon,Weitao Shan,David A. Cullen,Stavros Karakalos,Mengjie Chen,Daming Gu,Karren L. More,Guofeng Wang,Zhenxing Feng,Zhen-Bo Wang,Gang Wu +13 more
TL;DR: This approach is able to deconvolute Fe-N bond formation from complex carbonization and nitrogen doping, which correlates Fe-n bond properties with activity and stability of FeN 4 sites as a function of thermal activation temperatures.
Journal ArticleDOI
Single Cobalt Sites Dispersed in Hierarchically Porous Nanofiber Networks for Durable and High-Power PGM-Free Cathodes in Fuel Cells.
Yanghua He,Hui Guo,Sooyeon Hwang,Xiaoxuan Yang,Zizhou He,Jonathan Braaten,Stavros Karakalos,Weitao Shan,Maoyu Wang,Hua Zhou,Zhenxing Feng,Karren L. More,Guofeng Wang,Dong Su,David A. Cullen,Ling Fei,Shawn Litster,Gang Wu +17 more
TL;DR: The combination of the intrinsic activity and stability of single Co sites, along with unique catalyst architecture, provide new insight into designing efficient PGM-free electrodes with improved performance and durability.
Journal ArticleDOI

Journal ArticleDOI
Engineering Atomically Dispersed FeN4 Active Sites for CO2 Electroreduction
Nadia Mohd Adli,Weitao Shan,Sooyeon Hwang,Widitha Samarakoon,Stavros Karakalos,Yi Li,David A. Cullen,Dong Su,Zhenxing Feng,Guofeng Wang,Gang Wu +10 more
TL;DR: Using a Fe-N-C model catalyst derived from the ZIF-8, three key morphological and structural elements of FeN 4 sites are deconvoluted, including particle sizes of catalysts, Fe content, andFe-N bond structures, which elucidated the origin of intrinsic activity improvement associated with the optimal local strain on the Fe- N bond.
Journal ArticleDOI
Dynamically Unveiling Metal-Nitrogen Coordination during Thermal Activation to Design High-Efficient Atomically Dispersed CoN 4 Active Sites.
Yanghua He,Qiurong Shi,Weitao Shan,Xing Li,A. Jeremy Kropf,Evan C. Wegener,Joshua Wright,Stavros Karakalos,Dong Su,David A. Cullen,Guofeng Wang,Deborah J. Myers,Gang Wu +12 more
TL;DR: In this article, the structural evolution of CoN4 sites during thermal activation was investigated by developing a zeolitic imidazolate framework (ZIF)-8-derived carbon host as an ideal model for Co2+ ion adsorption.
