Uniform 3D flower-like MoS2nanostructures were successfully synthesized through a facile two-step hydrothermal method and had high supercapacitor and adsorption behaviors toward Rhodamine B.

Porous Co3O4 ultrathin nanosheets exhibited good sensitivity and low concentration selectivity to ethanol.

Co9S8/Ni3S2 nanoflakes have been successfully designed and constructed on nickel foam substrate via a simple one-pot hydrothermal synthesis and exhibit high performance as supercapacitor.
