Iron Hexadecafluorophthalocyanine Nanoparticle/Porous Carbon Composites as Cathode Materials for Li-S Batteries / Xu, Zhanwei (Shaanxi University of Science and Technology) ; Niu, Hang (Shaanxi University of Science and Technology) ; Zhang, Ying (Shaanxi University of Science and Technology) ; Chen, Siyu (Institut Català de Nanociència i Nanotecnologia) ; et al Mostra tots els 8 autors
The shuttle behavior and sluggish conversion kinetics of polysulfides (LiPSs) significantly hinder sulfur utilization and cycle stability of lithium-sulfur (Li-S) batteries. Herein, iron hexadecafluorophthalocyanine (FePcF) nanoparticles were in situ tailored on oxidized apple pomace carbon (OAPC) with a 3D porous structure to construct a high-performance FePcF/OAPC sulfur host for advanced Li-S batteries.

Efficient nitrate-to-ammonia conversion for circular nitrogen economy / Costa, Gabriel F. (Institut Català de Nanociència i Nanotecnologia) ; Nagao, Raphael (Institut Català de Nanociència i Nanotecnologia)
The development of an economically feasible system for the electrochemical treatment of nitrate-rich wastewater is hampered by the complexity of the matrices. The use of membrane-free systems can be beneficial to avoid contamination by organic impurities and dissolved salts, but their implementation is challenging considering that ammonia is susceptible to anodic oxidation.
