The Cover Feature illustrates the CO oxidation on the surface of integrated cobalt oxide based nanoarray catalysts. In their Full Paper, S. Mo et al. reported a facile strategy for the in situ growth of a Co 3 O 4 ‐based precursor with unique hierarchical architectures oriented perpendicular to Ni surfaces. They used in situ Raman spectroscopy to record the structural transformation of Co 3 O 4 directly during the reaction, which confirmed that CO oxidation on the surface of Co 3 O 4 can proceed through the Langmuir–Hinshelwood mechanism (< 200 °C) and the Mars–van Krevelen mechanism (> 200 °C). More information can be found in the Full Paper by S. Mo et al. on page 3012 in Issue 14, 2018 (DOI: 10.1002/cctc.201800363).
