TL;DR: A practical synthesis method to produce isolated single platinum atoms and clusters using the atomic layer deposition technique and indicates that the partially unoccupied density of states of the platinum atoms' 5d orbitals on the nitrogen-doped graphene are responsible for the excellent performance.

TL;DR: In this article, Nitrogen-doped graphene as a metal-free catalyst for oxygen reduction was synthesized by heat-treatment of graphene using ammonia and the optimum temperature was 900 °C.

TL;DR: It is proposed that tetrabutyl ammonium (TBA) cations most probably intercalate into the gaps and the defects during electrochemical cycling and break the tubes near the defects.

TL;DR: In this paper, the atomic layer deposition (ALD) technique was used to synthesize single Pt atoms anchored to graphene nanosheet using the ALD technique, and the single-atom catalysts exhibit significantly improved catalytic activity (up to 10 times) over that of the state-of-the-art commercial Pt/C catalyst.

TL;DR: In this article, the effect of nitrogen doping on the structure of graphene has been systematically investigated by various characterization techniques such as SEM, TEM, BET, Raman and XRD analysis were used to distinguish the difference of the microstructures; and FT-IR, XPS, especially XANES were performed to elucidate the bonding information such as C-N.
