General Formation of M-MoS3 (M = Co, Ni) Hollow Structures with Enhanced Electrocatalytic Activity for Hydrogen Evolution.

Complex molybdenum-based ternary or multinary sulfides hollow structures are developed via a fast precipitation process, together with a subsequent annealing treatment. Benefiting from the merits of high-curvature surfaces with excellent intrinsic catalytic activity, the obtained unique hollow structures exhibit enhanced performance as electrocatalysts for hydrogen production in acidic media.
