TL;DR: In this paper, a series of graphene-confined 3D transition metals (Mn, Fe, Co, Ni, and Cu) were screened, yet only single Fe atoms could catalyze the methane conversion, and they found that methane conversion proceeds on the O-FeN4-O active site along a radical pathway to produce CH3OH and CH3OOH first, and then the generated CH3HO can be further catalyzed to form HOCH2OOH and HCOOH at room temperature.

TL;DR: The confinement of mesopores played a key role in improving the thermal stabilities of silver nanoparticles (stable up to 773 K without any observable coarsening), which is essential to the further investigations on their chemical (e.g., catalytic) properties.

TL;DR: In this article, the authors reported that CO2 can dissociate at sulfur vacancies in MoS2 nanosheets to yield surface-bound CO and O at room temperature, thus enabling a highly efficient low-temperature hydrogenation of CO2 to methanol.

TL;DR: In this paper, a uniform single-crystal boehmite leaf-like nanosheets with high anisotropy (with a lateral size of (4.5 − 0.5μm) and a thickness of 60 − 90 nm) and flower-like superstructures consisting of singlecrystal petals were synthesized for the first time by a simple hydrothermal method.

TL;DR: In this article, different metal films (Co, Ni, Au, and Ag) were deposited on graphene and the interactions between these metals and graphene were studied by Raman spectroscopy.
