Synthesis, characterization, surface properties and energy device characterstics of 2D borocarbonitrides, (BN)xC1−x, covalently cross-linked with sheets of other 2D materials
TL;DR: In this paper, the surface areas and CO2 and H2 adsorption properties of two borocarbonitride compositions, (BN)0.75C0.25 and (BN)-MoS2 0.3C 0.7, were determined.

Remarkable photochemical HER activity of semiconducting 2H $$\hbox {MoSe}_{{2}}$$ MoSe 2 and $$\hbox {MoS}_{{2}}$$ MoS 2 covalently linked to layers of 2D structures and of the stable metallic 1T phases prepared solvo- or hydro-thermally $$^{\S }$$ §
TL;DR: In this article, the authors showed the important role played by covalent cross-linking of layered compounds for enhancing the photochemical hydrogen evolution reaction (HER) activity significantly, by linking the layers of the dichalcogenide with layers of other 2D materials such as carbon-rich borocarbonitride (BCN), and showed that the 1T forms are generally superior to the covalently linked 2H forms.
