TL;DR: In this paper, the role of twins in electrochemical nitrogen reduction (NRR) was studied for the first time, and the Pd icosahedron achieved a high NH3 yield and FE, which were 17.56 μg h −1 cm−2 (43.9 μg h−1 mgcat.−1) and 31.98% respectively.
Journal ArticleDOI
Facet-controlled palladium nanocrystalline for enhanced nitrate reduction towards ammonia.
Yi Han,Xinyi Zhang,Wenwen Cai,Huan Zhao,Yanyun Zhang,Yuyao Sun,Zhiqiang Hu,Shaoxiang Li,Jianping Lai,Lei Wang +9 more
TL;DR: In this paper, the Pd nanocrystalline with a well-desired facet can act as a highly efficient NO3−RR electrocatalyst for ambient ammonia synthesis, which is considered an appealing way for producing ammonia (NH3) under ambient conditions and solving environmental problems caused by nitrate.
Journal ArticleDOI
Significantly enhanced electrocatalytic N2 reduction to NH3 by surface selenization with multiple functions
Wenwen Cai,Yi Han,Hongdong Li,Wenjing Qi,Jixiang Xu,Xueke Wu,Huan Zhao,Xinyi Zhang,Jianping Lai,Lei Wang +9 more
TL;DR: In this paper, the authors reported RuO2 nanoparticles with different degrees of surface selenation, which showed excellent NRR performance at low overpotential, achieving NH3 yield rate of 12.97 μg h−1 cm−2 and 26.01% at −0.1 V vs. RHE.
