Front Cover: Tracking the Mode of Carbon Deposition During Dry Reforming of Methane over Ni/γ-Al2O3 (ChemCatChem 8/2025)

Abstract

The Front Cover illustrates the dynamics of atomic-scale reactions using both models and real images. The nickel atoms, depicted in purple, represent active centers on the catalyst surface, while the red oxygen, black carbon, and white hydrogen atoms signify the reacting gas molecules. The blue-gray atoms in the background symbolize the alumina support. The real TEM image is in the background: the Octopus carbon formed over large Ni particles due to a favorable methane adsorption over metal, while CO₂ is preferentially adsorbed on the support. In their Research Article (DOI: 10.1002/cctc.202401856), D. Uner and co-workers report how they successfully characterized the carbon structures through SS ¹³C NMR spectroscopy and how intermittent pulses of CO₂ inhibited coke formation during steady-state reaction under CO₂/CH₄ = 1:1.
