Although oxygen reduction reaction (ORR) as an effective signal amplification strategy has been extensively investigated for the improvement of sensitivity electrochemical sensors, their activity and stability are still a great challenge. Herein, single-atom Fe (FeSA) nanoparticles (FeNP) on nitrogen-doped carbon (FeSA/FeNP) catalysts demonstrate highly active stable ORR performance, thus achieving sensitive sensing organophosphorus pesticides (OPs). Experimental investigations indicate that FeNP in FeSA/FeNP can improve by adjusting electronic structure FeSA sites. Besides, owing to excellent catalase-like activity, rapidly consume situ generated H2O2 process avoid leakage sites, thereby improving ORR. Utilizing performance FeSA/FeNP, sensor OPs is established based thiocholine-induced poison demonstrating satisfactory stability. This work provides new insight into design high sensing.

Palladium (Pd), a rare and precious metal, is highly valued due to its non-renewable nature significant cost. Therefore, recovering palladium from industrial wastewater of great importance but remains challenge. Herein, composite aerogel adsorbent has been developed by linking bipyridine covalent organic framework, termed TpBpy, with chitosan (CS) through robust bonds. The resulting TpBpy/CS employed for the selective separation recovery at low concentrations in real wastewater. Experimental results reveal that maximum adsorption capacity Pd(ii) 274.4 mg g-1 pH 1. Additionally, even presence other coexisting ions 100 times higher than Pd(ii), efficiency above 99%. Mechanistic investigations indicate aerogels primarily occurs coordination between pyridine N as well electrostatic interaction protonated amino groups Pd(ii). Moreover, demonstrates exceptional reusability, maintaining an 99% after nine adsorption-desorption cycles. Overall, promising monolithic efficient acidic selectivity, demonstrating substantial potential practical applications.

This study utilized the Schiff base reaction as a chemical bonding method to successfully graft 2-aminopyridine onto oxidized sodium alginate, resulting in formation of modified alginate (OSM). Subsequently, OSM/polyacrylic acid (OSM/PAA) hydrogel was synthesized via thermally initiated free radical polymerization process and evaluated an adsorbent for removal heavy metal ions from wastewater. Comprehensive characterization prepared samples performed using FT-IR, SEM, TGA. The influence temperature, pH, dosage, contact time, ion concentration on adsorption capacity OSM/PAA simulated wastewater thoroughly investigated. Additionally, detailed analysis thermodynamics, kinetics, mechanisms conducted. Experimental results indicated that at 25 °C, pH 5.0, dosage 0.4 g/L, maximum capacities Cu(II), Zn(II), Ni(II) were 367.64 mg/g, 398.4 409.83 respectively. These findings suggest by is spontaneous, heterogeneous with significant potential practical applications treatment.
