Hydrogen Peroxide Production on a Carbon …

Photocatalytic production of hydrogen peroxide (H 2 O 2) from earth‐abundant water and O 2 is a desirable artificial photosynthesis for solar fuel production. A metal‐free hybrid photocatalyst consisting of pyromellitic diimide‐doped carbon nitride (g‐C 3 N 4 /PDI), boron nitride (BN), and reduced graphene oxide (rGO) was prepared. The g‐C 3 N 4 /PDI‐BN‐rGO catalyst, when ...

Graphene and Boron Nitride: Members of Two …

Graphene and monoatomic boron nitride as members of the new class of two dimensional materials are discussed in this thesis. Since the discovery of graphene in 2004, various aspects of this one atom thick material have been studied with previously unexpected results.

[2011.11895] Moiré Commensurability and the …

2020-11-24 · The quantum anomalous Hall (QAH) effect is sometimes observed in twisted bilayer graphene (tBG) when it is nearly aligned with an encapsulating hexagonal boron nitride (hBN) layer. We propose that the appearance or absence of the QAH effect in individual devices could be related to commensurability between the graphene/graphene and graphene/hBN moiré patterns. We identify a …

Fast pick up technique for high quality …

2014-7-7 · We present a fast method to fabricate high quality heterostructure devices by picking up crystals of arbitrary sizes. Bilayer graphene is encapsulated with hexagonal boron nitride to demonstrate this approach, showing good electronic quality with mobilities ranging from 17 000 cm 2 V −1 s −1 at room temperature to 49 000 cm 2 V −1 s −1 at 4.2 K, and entering the quantum Hall regime ...

Graphene/hexagonal boron nitride (h-BN) vertical heterostructures have recently revealed unusual physical properties and new phenomena, such as commensurate-incommensurate transition and fractional quantum hall states featured with Hofstadter's butterfly. Graphene-based devices on h …

Direct chemical conversion of graphene to boron- and ...

Graphene and hexagonal boron nitride are typical conductor and insulator, respectively, while their hybrids hexagonal boron carbonitride are promising as a semiconductor. Here we demonstrate a direct chemical conversion reaction, which systematically converts the hexagonal carbon lattice of graphene …

Synthesis of Boron Nitride Coating on Graphene

A method to synthesize boron nitride (BN) coating on the surface of graphene has been developed. BN coating was synthesized by the direct reaction of sodium borohydride and ammonium chloride at a ...

Interlayer shear of nanomaterials: …

Abstract. In this paper, the interlayer sliding between graphene and boron nitride (h-BN) is studied by molecular dynamics simulations. The interlayer shear force between h-BN/h-BN is found to be six times higher than that of graphene/graphene, while the interlayer shear between graphene/h-BN is approximate to that of graphene/graphene.
