The Front Cover shows the hydrogen evolution reaction (HER) driven by molybdenum sulfide‐based catalysts in different phases, namely the semiconducting 2H, metallic 1T, and amorphous MoS 2 . Whereas 2H‐MoS 2 has limited catalytic activity (mainly at the edges), both the 1T and amorphous phases exhibit extraordinarily high hydrogen evolution activity. Detailed bond structure analysis is performed on 1T and amorphous MoS 2 showing the presence of short Mo−S and Mo−Mo bonds in both phases. In comparison to the intrinsic short Mo−Mo and Mo−S bonds in amorphous MoS 2 , the distinct bond feature in the 1T phase is induced by Li intercalation and is therefore unstable under harsh HER conditions. More information can be found in the Communication by L. Wu et al. on page 4383 in Issue 19, 2019 (DOI: 10.1002/cssc.201901811).
