Formation of active sites for oxygen reduction reactions by transformation of nitrogen functionalities in nitrogen-doped carbon nanotubes.

Tiva Sharifi, +3 more
- 08 Oct 2012 - 
TL;DR: This study concludes that quaternary nitrogen valley sites, N-Q(valley), are the most active sites for ORR in N-CNTs and proposes how to treat samples to maximize the catalytic efficiency of such samples.
Journal ArticleDOI

Synergistic Effects between Atomically Dispersed Fe−N−C and C−S−C for the Oxygen Reduction Reaction in Acidic Media

Hangjia Shen, +11 more
- 23 Oct 2017 - 
TL;DR: This work has obtained a sulfur-doped Fe/N/C catalyst (denoted as Fe/SNC) that exhibits much better ORR activity than the sulfur-free variant (Fe/NC) in 0.5 m H2 SO4 in acidic solution.
Journal ArticleDOI

Hierarchically Ordered Porous Carbon with Atomically Dispersed FeN 4 for Ultraefficient Oxygen Reduction Reaction in Proton-Exchange Membrane Fuel Cells

Mengfei Qiao, +9 more
- 10 Feb 2020 - 
TL;DR: In a real PEMFC, FeN 4 /HOPC-c-1000 exhibit significantly enhanced current density and power density compared to FeN4 /C without an optimized pore structure, implying an efficient utilization of the active sites and enhanced mass transfer to promote the oxygen reduction reaction (ORR).
Journal ArticleDOI

Atomically FeN2 moieties dispersed on mesoporous carbon: A new atomic catalyst for efficient oxygen reduction catalysis

Hangjia Shen, +8 more
- 01 May 2017 - 
TL;DR: In this paper, earth-abundant materials with Fe-N-C centers have been identified as promising catalysts for oxygen reduction reaction (ORR), but these alternatives for Pt catalysts are usually the porphyrin-like...
Journal ArticleDOI

Controlled Synthesis of CeO2/Graphene Nanocomposites with Highly Enhanced Optical and Catalytic Properties

Linhai Jiang, +12 more
- 18 May 2012 - 
TL;DR: In this article, the (200)-terminated surface/graphene sheet composites modified electrode showed much higher sensitivity and excellent selectivity in its catalytic performance compared to a CeO2 nanoparticle-modified electrode.
