1. Sustainable mercury monitoring using graphitic carbon nitride as a 2D binding layer in diffusive gradient thin filmsDmitrii Deev, Raghuraj S.

In this study, we report the first application of graphitic carbon nitride (GCN) nanosheets as a metal-free and sustainable binding material for Hg²⁺ monitoring in DGT systems, addressing key limitations of current approaches. Few-layer GCN nanosheets were synthesized via thermal polymerization followed by protonation-assisted exfoliation and comprehensively characterized using X-ray diffraction (XRD), X-ray photoelectron spectroscopy (XPS), transmission electron microscopy (TEM), atomic force microscopy (AFM), Raman spectroscopy, and scanning electron microscopy (SEM). These analyses confirmed the formation of a structurally stable, nitrogen-rich framework with abundant coordination sites. The GCN–agarose (AG–GCN) composite binding layer demonstrated high mercury binding efficiency (>90%) at environmentally relevant concentrations (2.5–10 ng/mL) and near-neutral pH, attributed to strong coordination between Hg²⁺ ions and electron-donating nitrogen sites within the heptazine structure. Compared to conventional DGT binding phases, the proposed system offers enhanced sustainability, metal-free composition, and strong affinity toward mercury, highlighting its potential for next-generation passive environmental monitoring and advanced nanomaterial-based sensing platforms.
