Abstract

original image

Graphen light: Ein N-dotiertes 3D-Graphen wurde hergestellt, das die bisher niedrigste Dichte einer Graphen-Architektur aufweist [(2.1±0.3) mg cm−3; siehe Foto einer Probe auf einer Pusteblume]. Die Adsorptionskapazität des Materials für Öle und organische Lösungsmittel ist weit höher als die der besten Kohlenstoffsorbentien, und es ist außerdem ein vielversprechendes Elektrodenmaterial für Superkondensatoren (484 F g−1) und als metallfreier Katalysator für die Sauerstoffreduktionsreaktion.
