Amine-functionalized holey graphene as a highly active metal-free catalyst for the oxygen reduction reaction
TL;DR: Amine functionalized holey graphene (AFHG) has been used as a metal-free catalyst for the oxygen reduction reaction (ORR) as discussed by the authors, which shows that AFHG is highly active for the ORR and exhibits higher electrocatalytic activity than graphene, nitrogen-doped graphene (NG) and amine functionalized graphene(AFG), which could be demonstrated from its higher current density and more positive half-wave and onset potentials for ORR.

High performance of a free-standing sulfonic acid functionalized holey graphene oxide paper as a proton conducting polymer electrolyte for air-breathing direct methanol fuel cells
TL;DR: In this paper, the SDBS-HGO membranes were used as proton exchange membranes for air-breathing direct methanol fuel cell applications, and the electrochemical results showed that the air-Breathing Direct Methanol Fuel Cell (DME) with SDBSs exhibit much higher performance and better stability than the Nafion® 112.
