The hydrothermal synthesis of 3D hierarchical porous MoS2 microspheres assembled by nanosheets with excellent gas sensing properties

Abstract

3D hierarchical porous MoS2 microspheres assembled by nanosheets were successfully fabricated via a facile yet efficient hydrothermal process using an assistance of CTAB as soft template which had significant effects on the final morphology of MoS2 products. The possible formation mechanism of the harvested porous MoS2 microspheres were preliminarily presented on the basis of the experimental results. Moreover, the gas sensing properties of the samples were investigated. The hierarchical porous MoS2 microspheres are found to exhibit an excellent gas response capability, good response-recovery properties, reproducibility and selectivity, which provides further evidence that assistance CTAB is critical for governing the morphology and properties of the MoS2.
