Cover Picture: Preparation of Nickel Phosphide Hydrodesulfurization Catalysts Assisted by Supercritical Carbon Dioxide (ChemCatChem 21/2015)

The Front Cover shows a new preparation method to obtain Ni 2 P/SiO 2 catalysts assisted by scCO 2 . The upper part of the image is inspired by the Venus planet, known to be covered by scCO 2 , representing the reactor used for the catalyst design. In their Communication, B. Motos‐Pérez et al. describe the utilization of phosphorous precursors with different oxidation states to obtain highly active Ni 2 P NPs, well‐known as active HDS catalysts. Catalysts thus obtained are highly active in comparison with non‐supercritical references and as active as conventional promoted NiMoS/Al 2 O 3 . More details can be found in the Communication by D. Uzio, C. Aymonier et al. on page 3441 in Issue 21, 2015 (DOI: 10.1002/cctc.201500755).
