摘要：1) Background: Hollow nanostructures have gained great attention due to their excellent performance and wide range of applications. In this paper, a hollow nanoreactant is fabricated for investigating the chemisorption of antimony in water. 2) Methods: We constructed the hierarchical LDH grown on hollow carbon spheres via the in-situ etching-growth from MOF precursor. The synthesized nanoreactant was evaluated with the adsorption of Sb, which shows ultra-smooth kinetics curves at various conditions, including five different initial concentrations and three different temperatures. Combining the characterizations of XPS, FT-IR and the results of adsorption, the chemisorption of antimony was illustrated that the inner-sphere complexation, hydrogen bonding and dehydration, as well as redox reaction may play important roles in the immobilization process of antimony. 3) Significant Findings: This material exhibits a steady interaction between the adsorbent and antimony species, which suggests the dominant chemisorption procedure. In addition, the as prepared HCSs@Mn/Co-LDH has high adsorption capacities, especially at low antimony concentrations. The excellent performance is benefited by the construction of the hollow structure and the synergistic interaction between the components of the composite.
