Published: Feb. 21, 2025

Abstract The shuttle effect and sluggish reaction kinetics of soluble lithium polysulfides (LiPSs) significantly impede the practical application lithium‐sulfur (Li‐S) batteries. Topological semimetals (TSMs) offer a promising solution to these challenges due their unique topological surface states. This study synthesizes reduced graphene oxide (rGO)‐loaded Pd 3 Sn TSMs (Pd Sn@rGO) that are prepared by NaBH 4 reduction method. obtained Sn@rGO composite has notably stronger adsorption capability for LiPSs than pure rGO verified experiments density functional theory (DFT) calculations. states facilitate acceptance electrons from Li 2 S 6 during process, thereby enhancing accelerating redox reactions. Furthermore, deposition confirm effective catalytic role in nucleation process S. Consequently, Li‐S batteries with modified separators showcase exceptional rate performance across various current densities along impressive cycling stability (decay 0.0598% per cycle at 1C). work highlights catalyzing sulfur reactions underscores potential other TSM electrocatalysts

Graphitic Carbon Nitride Nanomaterials-Based Electrochemical Sensing Interfaces for Monitoring Heavy Metal Ions in Aqueous Environments

Nanomaterials, Journal Year: 2025, Volume and Issue: 15(7), P. 564 - 564

Published: April 7, 2025

The persistent threat of heavy metal ions (e.g., Pb2+, Hg2+, Cd2+) in aqueous environments to human health underscores an urgent need for advanced sensing platforms capable rapid and precise pollutant monitoring. Graphitic carbon nitride (g-C3N4), a metal-free polymeric semiconductor, has emerged as revolutionary material constructing next-generation environmental sensors due its exceptional physicochemical properties, including tunable electronic structure, high chemical/thermal stability, large surface area, unique optical characteristics. This review systematically explores the integration g-C3N4 with functional nanomaterials nanoparticles, oxide nanomaterials, carbonaceous materials, conduction polymer) engineer high-performance interfaces detection. structure-property relationship is critically analyzed, emphasizing how morphology engineering (nanofibers, nanosheets, mesoporous) functionalization strategies enhance sensitivity selectivity. Advanced detection mechanisms are elucidated, electrochemical signal amplification, photoinduced electron transfer processes enabled by g-C3N4’s tailored bandgap active sites. Furthermore, this addresses challenges real-world deployment, such scalable nanomaterial synthesis, matrix interference mitigation, long-term reliable work provides valuable insights advancing g-C3N4-based technologies toward sustainable monitoring intelligent pollution control systems.
