TL;DR: In this paper, the use of the ionic liquid 1-butyl-3methylimidazolium tetrafluoroborate ([bmim][BF4]) as reaction medium, and of iron (III) chloride hexahydrate as a catalyst is described for the efficient preparation of α,α′-bis(substituted benzylidene)cycloalkanones.

TL;DR: The oxidation of CO by molecular O2 on a single cobalt atom embedded in a hexagonal boron nitride monolayer is investigated using first-principles calculations with dispersion-correction and it is found that the single Co atom prefers to reside in a bor on vacancy and possesses great stability.
Abstract: A single metal atom stabilized on two dimensional materials (such as graphene and h-BN) exhibits extraordinary activity in the oxidation of CO. The oxidation of CO by molecular O2 on a single cobalt atom embedded in a hexagonal boron nitride monolayer (h-BN) is investigated using first-principles calculations with dispersion-correction. It is found that the single Co atom prefers to reside in a boron vacancy and possesses great stability. There are three mechanisms for CO oxidation: the traditional Eley-Rideal (ER) and Langmuir-Hinshelwood (LH) mechanisms and the termolecular Eley-Rideal (TER) mechanism proposed recently. Given the relatively small reaction barriers of the rate-limiting steps for the ER, LH and TER mechanisms (0.59, 0.55 and 0.41 eV, respectively), all three mechanisms are able to occur at low temperature. The current study may provide useful clues to develop low cost single atom catalysts.

TL;DR: Based on density functional theory, the characteristics of n- and p-type impurities are investigated firstly by means of group V and VII atoms substituting sulfur atoms in the SnS2 monolayer nanosheets and show that the formation energy and transition levels depend highly on the atomic size and electronegativity of the impurity atom.
Abstract: Based on density functional theory, the characteristics of n- and p-type impurities are investigated firstly by means of group V and VII atoms substituting sulfur atoms in the SnS2 monolayer nanosheets. Numerical results show that the formation energy and transition levels depend highly on the atomic size and electronegativity of the impurity atom. The formation energies increase with the increasing impurity atom size for each considered doping case. For group V atom-doped SnS2 monolayer nanosheet systems, the calculations of the transition level indicate that N, P or As doping is not effective for p-type conductivity. However, for group VII atom doping cases, F, Cl, Br and I impurities can offer effective n-type carriers in the SnS2 monolayer nanosheets.
