Journal ArticleDOI
P-block single-metal-site tin/nitrogen-doped carbon fuel cell cathode catalyst for oxygen reduction reaction
Fang Luo,Aaron Roy,Luca Silvioli,David A. Cullen,Andrea Zitolo,Moulay Tahar Sougrati,Ismail Can Oğuz,Tzonka Mineva,Detre Teschner,Stephan Wagner,Ju Wen,Fabio Dionigi,Ulrike I. Kramm,Jan Rossmeisl,Frédéric Jaouen,Peter Strasser +15 more
TL;DR: The superior proton-exchange membrane fuel cell performance of SnNC cathode catalysts under realistic, hydrogen–air fuel cell conditions, particularly after NH3 activation treatment, makes them a promising alternative to today’s state-of-the-art Fe-based catalysts.
Journal ArticleDOI
Establishing reactivity descriptors for platinum group metal (PGM)-free Fe–N–C catalysts for PEM fuel cells
Mathias J.M. Primbs,Yanyan Sun,Aaron Roy,Daniel Malko,Asad Mehmood,Moulay Tahar Sougrati,Pierre-Yves Blanchard,Gaetano Granozzi,Tomasz Kosmala,Giorgia Daniel,Plamen Atanassov,Jonathan Sharman,Christian Durante,Anthony Kucernak,Deborah J. Jones,Frédéric Jaouen,Peter Strasser +16 more
TL;DR: In this article, the authors report a comprehensive analysis of the catalytic oxygen reduction reaction (ORR) reactivity of four of today's most active benchmark platinum group metal-free (PGM-free) iron/nitrogen doped carbon electrocatalysts (Fe-N-Cs) in PEMFC.
Journal ArticleDOI
Platinum group metal-free NiMo hydrogen oxidation catalysts: high performance and durability in alkaline exchange membrane fuel cells
Sadia Kabir,Kenneth Lemire,Kateryna Artyushkova,Aaron Roy,Madeleine Odgaard,Debbie Schlueter,Alexandr G. Oshchepkov,Antoine Bonnefont,Elena R. Savinova,Dinesh C. Sabarirajan,Pratiti Mandal,Ethan J. Crumlin,Iryna V. Zenyuk,Plamen Atanassov,Alexey Serov +14 more
TL;DR: In this article, a carbon-supported bimetallic nickel-molybdenum catalyst was synthesized by thermal reduction of transition metal precursors on the surface of a carbon support (KetjenBlack 600J).
Journal ArticleDOI
Anode Catalysts for Direct Hydrazine Fuel Cells: From Laboratory Test to an Electric Vehicle
Alexey Serov,Monica Padilla,Aaron Roy,Plamen Atanassov,Tomokazu Sakamoto,Koichiro Asazawa,Hirohisa Tanaka +6 more
TL;DR: Novel highly active electrocatalysts for hydrazine hydrate fuel cell application were developed, synthesized and integrated into an operation vehicle prototype and tests the world highest activity with peak current density.
Journal ArticleDOI
High loading of single atomic iron sites in Fe–NC oxygen reduction catalysts for proton exchange membrane fuel cells
Asad Ullah Mehmood,Meng Gong,Frédéric Jaouen,Aaron Roy,Andrea Zitolo,Anastassiya Khan,Moulay Tahar Sougrati,Mathias J.M. Primbs,A. Martinez Bonastre,Dash Fongalland,Goran Dražić,Peter Strasser,Anthony Kucernak +12 more
TL;DR: In this article , a carbon-nitrogen matrix using a sacrificial metal (Zn) in the initial synthesis step and then exchanging iron into this preformed matrix was used to achieve 7 wt% iron coordinated solely as single-atom Fe-N4 sites.
