Single-Shell Carbon-Encapsulated Iron Nanoparticles: Synthesis and High Electrocatalytic Activity for Hydrogen Evolution Reaction
Mohammad Tavakkoli,Tanja Kallio,Olivier Reynaud,Albert G. Nasibulin,Albert G. Nasibulin,Christoffer Johans,Jani Sainio,Hua Jiang,Esko I. Kauppinen,Kari Laasonen +9 more
TL;DR: In SCEINs the single carbon layer does not prevent desired access of the reactants to the vicinity of the iron nanoparticles but protects the active metallic core from oxidation, which opens new avenues for utilizing active transition metals such as iron in a wide range of applications.
Journal ArticleDOI
Electrochemical Activation of Single-Walled Carbon Nanotubes with Pseudo-Atomic-Scale Platinum for the Hydrogen Evolution Reaction
Mohammad Tavakkoli,Nico Holmberg,Rasmus Kronberg,Hua Jiang,Jani Sainio,Esko I. Kauppinen,Tanja Kallio,Kari Laasonen +7 more
TL;DR: In this paper, the authors achieved pseudo-atomic-scale dispersion of Pt, i.e. individual atoms or subnanometer clusters, on the sidewalls of single-walled carbon nanotubes (SWNTs) with a simple and readily upscalable electroplating deposition method.
Journal ArticleDOI
Highly active nitrogen-doped few-layer graphene/carbon nanotube composite electrocatalyst for oxygen reduction reaction in alkaline media
Sander Ratso,Ivar Kruusenberg,Merilin Vikkisk,Urmas Joost,Eugene Shulga,Ilmar Kink,Tanja Kallio,Kaido Tammeveski +7 more
TL;DR: In this paper, the performance of nitrogen-doped few-layer graphene/multi-walled carbon nanotube (FLG/MWCNT) composite catalyst has been investigated.
Journal ArticleDOI
