Journal ArticleDOI
Cobalt Fischer−Tropsch Catalysts Using Nickel Promoter as a Rhenium Substitute to Suppress Deactivation
TL;DR: In this article, the authors investigated the effect of nickel as a reduction and activity promoter on the performance of catalysts with cobalt as the Fischer−Tropsch (FT) metal and nickel and/or rhenium as promoters on alumina.
Journal ArticleDOI
Influence of hydrogen and halogen adsorption on the photocatalytic water splitting activity of C2N monolayer: A first-principles study
TL;DR: In this paper, the influence of molecular adsorbates such as H2, F2, Cl2, Br2, and I2 on the electronic properties and photocatalytic activity of the nitrogenated holey graphene (C2N) using hybrid density functional calculations including van der Waals interaction.
Journal ArticleDOI
In situ TEM observation of the Boudouard reaction: multi-layered graphene formation from CO on cobalt nanoparticles at atmospheric pressure
G. Marien Bremmer,Eirini Zacharaki,Anja Olafsen Sjåstad,Violeta Navarro,Joost W. M. Frenken,Patricia J. Kooyman +5 more
TL;DR: Using a MEMS nanoreactor in combination with a specially designed in situ Transmission Electron Microscope (TEM) holder and gas supply system, the formation of multiple layers of graphene encapsulating a cobalt nanoparticle was imaged live in a TEM during the Boudouard reaction.
Journal ArticleDOI
On the Thermal Stability and Structures of Layered Double Hydroxides Mg1–xAlx(OH)2(NO3)x·mH2O (0.18 ≤ x ≤ 0.38)
Anja Olafsen Sjåstad,Niels H. Andersen,Ponniah Vajeeston,Jayakumar Karthikeyan,Bjørnar Arstad,Arne Karlsson,Helmer Fjellvåg +6 more
TL;DR: In this article, the authors investigated the stability of layered double hydroxides with respect to humidity, dehydration and staging, nitrate group orientation, Al migration and crystal structure, and showed that flat-lying water and nitrate become tilted towards [1] at higher nitrate concentrations, accompanied by expansion along the c-axis.
Journal ArticleDOI
Stacking Faults and Polytypes for Layered Double Hydroxides: What Can We Learn from Simulated and Experimental X-ray Powder Diffraction Data?
TL;DR: This paper shows how X-ray powder diffraction (XRPD) can be used to reveal important features of the LDH crystal structure such as stacking faults, random interlayer shifts, anion-molecule orientation, crystal water content, distribution of interlayer distances, and also LDH slab thickness.
