Borocarbonitrides, B_xC_yN_z: Synthesis, Characterization, and Properties with Potential Applications

Abstract

Borocarbonitrides, BCN, constitute a new family of layered two-dimensional materials and can be considered to be derived from graphene. They can be simple composites containing graphene and BN domains or more complex materials possessing B-C and C-N bonds besides B-N and C-C bonds. Properties of these materials depend on the composition, and the method of synthesis, wherein one can traverse from the insulating end (BN) to the conducting end (graphene). In this article, we present an up-to-date review of the various aspects of borocarbonitrides including synthesis, characterization and properties. Some of the properties have potential applications, typical of them being in gas adsorption and energy devices such as supercapacitors, fuel cells and batteries. Performance of borocarbonitrides as catalysts in the electrochemical hydrogen evolution reaction is impressive. It is noteworthy that with certain compositions on borocarbonitrides, field-effect transistors can be fabricated.

Metallfreie Bor‐haltige Heterogenkatalysatoren

“…B. wurde die chemische Funktionalisierung der h ‐BN‐Kante breit untersucht, indem z. B. Hydroxy‐, Alkoxy‐, Amino‐, Alkyl‐ und andere Gruppen addiert wurden, die hilfreich für die Optimierung der Katalyse sein könnten . Eine Kupplung mit einem Cokatalysator könnte die Gesamteffizienz ebenfalls erhöhen.…”

“…Eine hexagonale Grapheneinheit kann eine h ‐BN‐Einheit in Form eines eingebetteten Defekts ersetzen und als elektronenziehende Gruppe wirken, um die elektronischen und optischen Eigenschaften des Materials zu steuern und zugleich die Monolagenstruktur und deren besondere Eigenschaften zu bewahren. Dementsprechend wurde C‐dotiertes h ‐BN ausführlich für katalytische Anwendungen studiert …”
