3D Cd–MoS2 Porous Monolith Fabricated Through a Self-Assembly Between Cd2+ Cations and MoS2 Nanoflakes

Abstract

Three-dimensional (3D) Cd–MoS2 monolith was fabricated at room temperature using 2D MoS2 nanoflakes as precursor and Cd[Formula: see text] cations through an interaction between the S atoms on the surface of the MoS2 nanoflakes and the Cd[Formula: see text] cations. Then, the Cd–MoS2 was measured by various techniques. The measurement results show that, to some extent, the Cd–MoS2 structure is still amorphous like that of the MoS2 nanoflakes, and it is also a kind of mesoporous material with a mean diameter of 15.70[Formula: see text]nm and specific surface area of 22.01[Formula: see text]m2/g. The adsorption results of Rhodamine B and Cu[Formula: see text] solutions demonstrate that such material exhibits relatively strong adsorption behaviors and high adsorption capability, and also it can be reused for the adsorption after the adsorbates are taken out.
