Abstract
This article demonstrates a versatile method to prepare the hollow PbS nanospheres via the template method. First, the latex poly (vinyl benzyl chloride) (PVBC) nanoparticles were synthesized by the radical polymerization, followed by the atom transfer reversible polymerization of lead (II) dimethacrylate (Pb (MA)2) on the surfaces of the latex nanoparticles. Then, the ethanethioamide was reacted with the nanoparticles to afford the PbS. By calcination at 600°C for 6 h, the template was removed to obtain the hollow PbS nanospheres. The structure, morphology and optical properties of the hollow PbS nanospheres were carefully investigated. The received hollow PbS nanospheres could be used for the controlled release of phenol after absorbing phenol solution.
Highlights
Semiconductor materials have been the focus in material science, due to their prominent optical and electronic properties and their potential applications for the preparation of optical signal processors and switches (Ridley et al 1999)
The PVBC latex nanoparticles were obtained by the radical polymerization of vinyl benzyl chloride (VBC) initiated by the AIBN in the presence of surfactants
The corresponding release behavior of phenol adsorbed by hollow PbS nanospheres was investigated
Summary
Semiconductor materials have been the focus in material science, due to their prominent optical and electronic properties and their potential applications for the preparation of optical signal processors and switches (Ridley et al 1999). The reaction mixture was stirred for additional 12 h, and the precipitation was isolated with centrifugation and washed with ethanol for 5 times. 100 mg of hollow PbS nanospheres was added into 20 mL phenol aqueous solution (0.01 M). The hollow PbS nanospheres were collected by centrifugation after incubation at room temperature for 24 h and washing by deionized water for 5 times. Hollow PbS nanospheres (100 mg) were heated to 300°C under nitrogen and added into 20 mL phenol aqueous solution (0.01 M) directly. Hollow PbS nanospheres (100 mg) were added into 20 mL phenol aqueous solution (0.01 M) and stirred for 3 h under vacuum at room temperature. The hollow PbS nanospheres embedded with phenol were added into dialysis bags, followed by the soaking in 50 mL deionized water under stirring. After 36 h, the data were collected and Polyether DBSA H2O VBC
