Front Cover: Effective Co_xS_y HER Electrocatalysts Fabricated by In‐Situ Sulfuration of a Metal‐Organic Framework (ChemElectroChem 23/2018)

Abstract

The Front Cover shows a sulfur‐ and nitrogen‐containing cobalt metal–organic framework (MOF). This MOF was chosen as a precursor to prepare cobalt sulfides through a phase‐control method and in situ sulfuration. These cobalt sulfides are promising as hydrogen evolution reaction (HER) electrocatalysts . The excellent HER performance of Co9S8/CoS1.097/rGO stems from the synergistic effect of Co9S8, CoS1.097, the high specific surface area, and the N, S‐doped carbon matrix.
