MoS2 hierarchical hollow cubic cages assembled by bilayers: one-step synthesis and their electrochemical hydrogen storage properties

Abstract

Micrometer scaled MoS₂ hierarchical hollow cubic cages assembled by bilayers can be synthesized via a one-step self-assembly coupled with intermediate crystal templating process without any surfactant, in which the intermediate K₂NaMoO₃F₃ crystal formed in-situ and then served as the self-sacrificed template based on the Kirkendall Effect; The MoS₂ hierarchical hollow cubic cages were employed for electrochemical hydrogen storage with a high capacity of 375 mAh g⁻¹ due to the more active edges exposing on the upright-standing nanoplates.
