Yuan Pan,Yuan Pan,Kaian Sun,Shoujie Liu,Shoujie Liu,Xing Cao,Konglin Wu,Konglin Wu,Weng-Chon Cheong,Zheng Chen,Yu Wang,Yang Li,Yunqi Liu,Dingsheng Wang,Qing Peng,Chen Chen,Yadong Li +16 more
TL;DR: A novel hybrid nanostructure with CoP nanoparticles embedded in a N-doped carbon nanotube hollow polyhedron (NCNHP) through a pyrolysis-oxidation-phosphidation strategy derived from core-shell ZIF-8@ZIF-67 is reported, benefiting from the synergistic effects between highly active CoP NPs and NCNHP.
Journal ArticleDOI
Design of Single-Atom Co–N5 Catalytic Site: A Robust Electrocatalyst for CO2 Reduction with Nearly 100% CO Selectivity and Remarkable Stability
Yuan Pan,Rui Lin,Yinjuan Chen,Yinjuan Chen,Shoujie Liu,Shoujie Liu,Wei Zhu,Xing Cao,Wenxing Chen,Konglin Wu,Konglin Wu,Weng-Chon Cheong,Yu Wang,Lirong Zheng,Jun Luo,Yan Lin,Yunqi Liu,Chenguang Liu,Jun Li,Qi Lu,Xin Chen,Dingsheng Wang,Qing Peng,Chen Chen,Yadong Li +24 more
TL;DR: Experiments and density functional theory calculations demonstrate single-atom Co-N5 site is the dominating active center simultaneously for CO2 activation, the rapid formation of key intermediate COOH* as well as the desorption of CO.
Journal ArticleDOI

Shengjie Wei,Ang Li,Jin-Cheng Liu,Zhi Li,Wenxing Chen,Yue Gong,Qinghua Zhang,Weng-Chon Cheong,Yu Wang,Lirong Zheng,Hai Xiao,Chen Chen,Dingsheng Wang,Qing Peng,Lin Gu,Xiaodong Han,Jun Li,Yadong Li +17 more
TL;DR: An unexpected phenomenon that noble metal nanoparticles can be transformed to thermally stable single atoms (Pd, Pt, Au-NPs) above 900 °C in an inert atmosphere and exhibited even better activity and selectivity than nanoparticles for semi-hydrogenation of acetylene.
Journal ArticleDOI
Enhanced oxygen reduction with single-atomic-site iron catalysts for a zinc-air battery and hydrogen-air fuel cell
Yuanjun Chen,Shufang Ji,Shu Zhao,Wenxing Chen,Juncai Dong,Weng-Chon Cheong,Rongan Shen,Xiaodong Wen,Lirong Zheng,Alexandre I. Rykov,Shichang Cai,Haolin Tang,Zhongbin Zhuang,Chen Chen,Qing Peng,Dingsheng Wang,Yadong Li +16 more
TL;DR: Benefiting from structure functionalities and electronic control of a single-atom iron active center, the catalyst shows a remarkable performance with enhanced kinetics and activity for oxygen reduction in both alkaline and acid media and shows promise for substitution of expensive platinum to drive the cathodic oxygen reduction reaction in zinc-air batteries and hydrogen-air fuel cells.
