The Cover Feature shows vanadium oxide species supported on a lamellar silica and the corresponding oxidation of methanol to formaldehyde on these active sites. In the Full Paper, Luiz H. Vieira et al. explain that surface speciation and active site‐support interactions in these materials play a substantial role in their reactivity. Isolated silanol groups were found to be more effective to disperse and stabilize vanadium oxides than increasing in surface area of the support. Differences in activation and the oxidation state dynamics behavior of active sites were then probed by methanol oxidation as a model reaction monitored by in situ spectroscopies (FTIR and XANES). More information can be found in the Full Paper by Luiz H. Vieira et al. on page 141 in Issue 1, 2020 (DOI: 10.1002/cctc.201901567).
