High Sulfur Content

The removal of lead ions from aqueous solutions was studied using a sulfur-impregnated adsorbent. Coal was mixed with K2S powder and then heated at 800°C for 30 min in nitrogen to produce a sulfur-impregnated adsorbent. The sulfur-impregnated adsorbent prepared had a high sulfur content and high specific surface area. The adsorbent showed a high removal ability for lead ions, and a high removal ratio for lead ions in binary Pb2+-Na+ and Pb2+-Mg2+ solutions. This characteristics were similar to unitary Pb2+ solutions. These results indicate that the sulfur-impregnated adsorbent has a high selective adsorption ability for lead ions in aqueous solutions.

Hierarchical Porous

High-entropy alloys (HEAs) present excellent mechanical properties. However, the exploitation of chemical properties of HEAs is far less than that of mechanical properties, which is mainly limited by the low specific surface area of HEAs synthesized by traditional methods. Thus, it is vital to develop new routes to fabricate HEAs with novel three-dimensional structures and a high specific surface area. Herein, we develop a facile approach to fabricate nanoporous noble metal quasi-HEA microspheres by melt-spinning and dealloying. The as-obtained nanoporous Cu30Au23Pt22Pd25 quasi-HEA microspheres present a hierarchical porous structure with a high specific surface area of 69.5 m2/g and a multiphase approximatively componential solid solution characteristic with a broad single-group face-centered cubic XRD pattern, which is different from the traditional single-phase or two-phase solid solution HEAs. To differentiate, these are named quasi-HEAs. The synthetic strategy proposed in this paper opens the door for the synthesis of porous quasi-HEAs related materials, and is expected to promote further applications of quasi-HEAs in various chemical fields.
