Surface chemistry and catalysis confined under two-dimensional materials
TL;DR: The confinement effect of the 2D cover leads to new chemistry in a small space, such as "catalysis under cover" and "electrochemistry under cover", which enable us to design advanced nanocatalysts encapsulated with 2D material shells which may present improved performance in many important processes of heterogeneous catalysis, electrochemistry, and energy conversion.

Simultaneous N-intercalation and N-doping of epitaxial graphene on 6H-SiC(0001) through thermal reactions with ammonia
TL;DR: In this paper, the surface functionalization of epitaxial graphene overlayers on 6H-SiC(0001) has been attempted through thermal reactions in NH3, which results in strong band bending at the SiC surface as well as decoupling of the overlayers from the substrate.

Surface free energies of solid metals: Estimation from liquid surface tension measurements
W.R. Tyson,W.A. Miller +1 more
TL;DR: In this paper, a semi-theoretical approach was proposed to estimate the surface energy of solids in the absence of direct experimental measurement. But this method was not suitable for the case of high-index surfaces.

The Structure of Catalytically Active Gold on Titania
Mingshu Chen,D. W. Goodman +1 more
TL;DR: Kinetic measurements for the catalytic oxidation of carbon monoxide show that the gold bilayer structure is significantly more active than the monolayer, thus eliminating particle shape and direct support effects.

Selective oxidation with dioxygen by gold nanoparticle catalysts derived from 55-atom clusters
Mark Turner,Vladimir B. Golovko,Vladimir B. Golovko,Owain P. H. Vaughan,Pavel Abdulkin,Ángel Berenguer-Murcia,Mintcho S. Tikhov,Brian F. G. Johnson,Richard M. Lambert +8 more
TL;DR: The observations suggest that catalytic activity arises from the altered electronic structure intrinsic to small gold nanoparticles, and that the use of 55-atom gold clusters may prove a viable route to the synthesis of robust gold catalysts suited to practical application.

CO2 Reforming of CH4
TL;DR: Although technological practice should minimize environmental impact, this is not always economically feasible as mentioned in this paper, and during the past decade, there has been increasing global concern over the environmental impact of technology.
