Electrochemical energy conversion and storage systems, including water electrolyzers, metal–air batteries, and solid-state batteries, are pivotal for the sustainable energy transition and future energy security. (1−3) Among diverse material candidates, transition-metal chalcogenides (TMDs), and molybdenum disulfide (MoS2) in particular, have become central due to earth abundance, tunable electronic structures, and remarkable catalytic activity for hydrogen evolution and other key reactions.
