In the developing nanotechnology world, numerous attempts have been made to prepare the nobel metallic nanoparticles (NPs), which can improve their applicability in diverse fields. In the present work, the biosynthesis of silver (Ag) NPs has been successfully achieved through the medicinal plant extract (PE) of G. resinifera and effectively used for the catalytic and antibacterial applications. The size dependant tuneable surface plasmon resonance (SPR) properties attained through altering precursor concentrations. The X-ray and selected area diffraction pattern for Ag NPs revealed the high crystalline nature of pure Ag NPs with dominant (111) phase. The high-resolution TEM images show the nonspherical shape of NPs shifting from spherical, hexagonal to triangular, with wide particle size distribution ranging from 13 to 44 nm. Accordingly, the dual-band SPR spectrum is situated in the UV-Vis spectra validating the non-spherical shape of Ag NPs. The functional group present on the Ag NPs surface was analysed by FT-IR confirms the capping and reducing ability of methanolic PE G. resinifera. Further, the mechanism of antimicrobial activity studied using electron microscope showed the morphological changes with destructed cell walls of E. coli NCIM 2931 and S. aureus NCIM 5021 cells, when they treated with Ag NPs. The Ag NPs were more effective against S. aureus and E. coli with MIC 128 mu g/ml as compared to P. aeruginosa NCIM 5029 with MIC 256 mu g/ml. Apart from this, the reduction of toxic organic pollutant 4-NP to 4-AP within 20 min reveals the excellent catalytic activity of Ag NPs with rate constant k = 15.69 s(-1). (C) 2020 Elsevier Ltd.

The search for effective catalysts in small molecule activation has intensified as industries seek efficient and costeffective solutions. Lithium (Li), known for its unique electronic properties, is of significant interest as a catalyst. However, its specific catalytic potential when anchored on graphene quantum dots (GQDs) has not been fully explored. This study investigates the catalytic potential of lithium (Li) adatoms on GQDs with various edge conformations (zigzag and armchair) and sizes (24 and 42 atoms). Using density functional theory (DFT), we examine the interactions of Li-decorated GQDs with small molecules such as H2, N2, CO, O2, and CO2. Our findings reveal that Li-GQD complexes exhibit optimal catalytic activity for all these molecules, based on binding energy, charge distribution, and bond length changes. The smallest GQD, coronene (24 carbon atoms), shows the most promising catalytic activity, providing experimental leads for synthesizing and testing efficient Li-anchored catalysts.

Fenton chemistry is a highly effective advanced oxidation processes (AOPs) for degrading organic pollutants in wastewater. However, conventional homogeneous Fenton systems face key drawbacks such as limited pH range, sludge formation, and poor recyclability. To address these challenges, iron oxide-based composites are used as efficient heterogeneous Fenton catalysts due to their strong redox activity and stability. In this work, Fe3O4-lignin nanocomposites were synthesized by a simple co-precipitation method and characterized using analytical techniques. The composites showed excellent performance, degrading 93% of MB far higher than pure Fe3O4 (48%). The enhanced activity stems from lignin's electron-donating and surface functional groups, which boost enhance Fe2+/Fe3+ cycling and promote center dot OH generation. A plausible degradation mechanism highlighting the synergistic role of lignin is proposed. The nanocomposites maintained high efficiency over five cycles, showing strong stability and magnetic recovery, making Fe3O4-lignin a promising and low-cost catalyst for wastewater treatment.
