Methylene blue (MB), a widely used industrial dye, is persistent pollutant with documented toxicity to aquatic organisms and potential health risks humans, even at ultra-trace levels. Conventional monitoring techniques such as UV–Vis spectroscopy fluorescence emission suffer from limited sensitivity, typically failing detect MB below ~10−7 M. In this study, we introduce surface-enhanced Raman (SERS) platform based on silver nanowire (AgNW) substrates that enables detection over an unprecedented dynamic range—from 1.5 × 10−4 M down 10−16 mapping confirmed the presence of individual signal hot spots lowest concentration, consistent theoretical number analyte molecules in probed area, thereby demonstrating near-single-molecule capability. The calculated enhancement factors reached up 1.90 1012, among highest reported for SERS-based platforms. A semi-quantitative calibration curve was established spanning twelve orders magnitude, successfully applied monitor degradation during two advanced oxidation processes (AOPs): TiO2 nanotube-mediated photocatalysis under UV irradiation atmospheric-pressure dielectric barrier discharge (DBD) plasma treatment. While rapidly lost sensitivity process, SERS continued characteristic peak ~1626 cm−1 throughout entire treatment duration. These signals revealed residual or partially degraded aromatic intermediates remained undetectable by conventional optical methods. results underscore ability AgNW-based provide ultra-sensitive, molecular-level insights into transformation pathways, enabling time-resolved tracking kinetics validating efficiency. This work highlights importance integrating AOPs powerful complementary strategy environmental water purification technologies. By delivering low-cost sensor (<USD 0.16 per test) promoting reagent-free methods, study directly advances SDG 6 (Clean Water Sanitation) 12 (Responsible Consumption Production).

Abstract Given the rising global energy demands and environmental concerns, developing efficient, non‐hazardous methods for producing electrocatalysts is crucial. The challenge lies not only in enhancing catalyst performance but also finding scalable, cost‐effective techniques large‐scale production. Plasma technologies, with their adaptability versatility conversion storage, have garnered significant attention. These chemical‐free provide precise control over material properties enable fabrication of high‐performance a single step. In this work, plasma technology leveraged to fabricate durable, NiMo electrocatalyst varying ratios (3:1, 3:2, 3:3) hydrogen evolution reaction (HER) using atmospheric spray. NiMo(3:3) composition demonstrates superior catalytic an overpotential 112 mV at current density 20 mA cm −2 . Further, Low‐pressure nitrogen treatment 15 minutes significantly reduces 78 mV, HER by altering surface boosting active site exposure. shows lower Tafel value 57.16 dec −1 high stability chronoamperometry under acidic conditions 30 hours, proving its sustainability harsh environments. This work provides solid evidence plasma's suitability as powerful sustainable approach fabricating advanced applications
