The Front Cover shows the catalyst system composed of homogeneous iron salt and heterogeneous Pd/C which are responsible for aqueous‐phase methane oxidation with oxygen in the presence of hydrogen even at low temperatures near 0 °C. In their Communication, Jongkyu Kang and Eun Duck Park reported the direct conversion of methane into methane oxygenates in an aqueous solution below room temperature using iron salts and Pd/C as catalysts and hydrogen peroxide as an oxidant. The hydrogen peroxide can be directly added or generated in situ from hydrogen and oxygen. The Pd/C catalyst greatly enhanced the reaction rate together with the iron salts. When hydrogen peroxide was directly added, the turnover frequency (TOF), defined as the moles of methane oxygenates per moles of Fe per unit time, at 293 K was 29 h ‐1 at pH = 2.3. The TOF at 293 K was 42 h ‐1 at pH = 1.3 with in situ generated hydrogen peroxide from hydrogen and oxygen. More information can be found in the Communication by Jongkyu Kang and Eun Duck Park on page 4247 in Issue 17, 2019 (DOI: 10.1002/cctc.201900919).
