· JVASP-155234· MnMo2S4

MnMo2S4 is a ternary sulfide compound combining manganese and molybdenum with sulfur, belonging to the layered transition metal dichalcogenide family. This material is primarily investigated in research contexts for electrochemical energy storage and catalysis applications, where its mixed-metal composition offers tunable electronic properties and active surface sites superior to single-metal sulfides. Its notable advantage lies in combining molybdenum's well-established catalytic activity with manganese doping to enhance electron transfer and reduce charge-transfer resistance, making it a promising candidate for hydrogen evolution reaction (HER) catalysts and alternative battery electrode materials where conventional precious-metal or pure MoS₂ systems may be cost-prohibitive or insufficient.
