Oleylamine Passivated Hydrophobic Sulfur Quantum Dots as Highly Efficient Adsorbents for Gaseous Iodine Sequestration

Abstract

Oleylamine-passivated hydrophobic Sdots was developed as efficient and promising adsorbent. Sdots displayed excellent optical properties and exhibited remarkable iodine vapor adsorption capacity of 2676 mg/g, surpassing many conventional adsorbents. Efficient capture of iodine was driven by the combined contributions of sulfur- and nitrogen-rich sites and hydrophobic surface of Sdots.
