Ionic Exchange of Metal–Organic Frameworks to Access Single Nickel Sites for Efficient Electroreduction of CO2
Changming Zhao,Xinyao Dai,Tao Yao,Wenxing Chen,Xiaoqian Wang,Jing Wang,Jian Yang,Shiqiang Wei,Yuen Wu,Yadong Li +9 more
TL;DR: This work adopts metal-organic frameworks (MOFs) to assist the preparation of a catalyst containing single Ni sites for efficient electroreduction of CO2 and presents some guidelines for the rational design and accurate modulation of nanostructured catalysts at the atomic scale.
Journal ArticleDOI
Atomically dispersed Fe3+ sites catalyze efficient CO2 electroreduction to CO.
TL;DR: Electrochemical data suggest that the Fe3+ sites derive their superior activity from faster CO2 adsorption and weaker CO absorption than that of conventional Fe2+ sites, whereas non–precious metal catalysts have shown low to modest activity.
Journal ArticleDOI
MOF-derived electrocatalysts for oxygen reduction, oxygen evolution and hydrogen evolution reactions
TL;DR: A wide range of applications based on these materials for ORR, OER, HER and multifunctional electrocatalysis are discussed, with an emphasis on the required features of MOF-derived carbon-based materials for the Electrocatalysis of corresponding reactions.
Journal ArticleDOI
Sintering of Catalytic Nanoparticles: Particle Migration or Ostwald Ripening?
TL;DR: In conclusion, the recent literature, especially on in situ studies, shows that OR is the dominant process causing the growth of nanoparticle size, and this could help to develop sinter-resistant catalysts, with the ultimate goal of designing catalysts that are self-healing.
