Although two-dimensional layered materials exhibit great promise for capturing and removing noble metal ions due to highly exposed active sites, the laminar structure of two-dimensional materials with high specific surface energy readily induces the accumulation of nanosheets and structural damage during ion adsorption reactions, greatly impeding their practical application. Herein, for the first time we developed a one-pot synthetic strategy to construct hierarchical SnS micro/nanocrystals with three-dimensional (3D) and urchinlike architecture in which the SnS nanosheets generate on the surface of the SnS microcenter.

The hierarchical urchinlike SnS materials were applied to capture the precious metal ions. As expected, high selectivity and efficient capture were achieved with an order of Au3+ > Pd2+ > Pt4+. Specifically, the as-synthesized urchinlike SnS maintains high efficiency for the capture of Au3+, Pt4+, and Pd2+ under strong acid conditions. In addition, the excellent capture capacities for Au3+ (793.7 mg g-1) and high distribution coefficients (Kd) of 1.97 × 106 mL g-1 place the SnS at the top of the range of materials known for capture. Fast adsorption kinetics analysis displays a kinetic constant of 9.103 × 10-6 g mg-1 min-1 according to the second order kinetic reaction equation.
