Abstract

original image

Einen einfachen Zugang zu B,N-dotiertem Graphen mit einstellbarer Zusammensetzung eröffnet das Tempern von Graphenoxid in Gegenwart von Borsäure und Ammoniak. Das gebildete BCN-Graphen (siehe Bild; C grau, H weiß, B rosa, N blau) ist bei der Sauerstoffreduktion in alkalischem Milieu ein aktiverer Katalysator als kommerzielle Pt/C-Elektrokatalysatoren.
