The main antioxidants present in plant extracts—quercetin, ?-carotene, gallic acid, ascorbic hydroxybenzoic caffeic catechin and scopoletin—are able to synthesize silver nanoparticles when reacting with a Ag NO3 solution. UV-visible absorption spectrum recorded most of the shows characteristic surface plasmon resonance band nanoparticles. Nanoparticles synthesised ascorbic, hydroxybenzoic, caff...

This study considers the progress of our previous for hydrogen generation depends on highly ordered metal oxide/plasmonic materials. reports preparation Ag2O-Ag/Au Al2O3 template (Ag2O-Ag/Au/Al2O3) photocatalytic sewage water splitting and H2 gas production. Ni imprinting, followed by two-step anodization procedures, prepare template. Ag2O-Ag Au materials are prepared inside using electrochemic...

In this study, silver oxide nanoparticles (Ag2O-NPs) were synthesized from nitrate using green amaranth leaf extract as a reducing agent. The degradation of caffeine and inactivation Escherichia coli (E. coli) by Ag2O-NPs was studied under compact fluorescent lamp illumination irradiation. Apart that, the antibacterial antioxidant activities also examined. Synthesized shaped like monodispersed ...

Interfacial interactions between late transition metal/metal oxide nanoparticles and oxide supports impact catalytic activity and stability. Here, we report the use of isothermal titration calorimetry (ITC), electron microscopy and density functional theory (DFT) to explore periodic trends in the heats of nanoparticle-support interactions for late transition metal and metal oxide nanoparticles ...

Hybrid multi-functional nanomaterials comprising two or more disparate materials have become a powerful approach to obtain advanced materials for environmental remediation applications. In this work, an Ag-Ag2O/TiO2@polypyrrole (Ag/TiO2@PPy) heterojunction has been synthesized by assembling a self-stabilized Ag-Ag2O (p type) semiconductor (denoted as Ag) and polypyrrole (π-conjugated polymer) o...

The objective of this work was to prepare and characterize a new and highly efficient modified membrane by in situ interfacial polymerization on porous polysulfone supports. The process used m-phenylenediamine and trimesoyl chloride in hexane, incorporating silver oxide Ag2O nanoparticles of varied concentrations from 0.001 to 0.1 wt%. Ag2O nanoparticles were prepared at different sizes varying...

Figure S1a,b show the optical and field emission scanning electron microscope (FESEM) images of the RuO2 NMs. The nanomaterials exhibited nanosheet morphology with length >1 μm and the width <100 nm. The X-ray diffraction (XRD) spectrum (Figure S1c) showed the prominent peaks at the diffraction angle (2θ) 28.00, 34.93, 39.64 and 54.00, representing (110), (101), (200) and (211) set of latti...

The interfacial bonding utilizing Ag2O-derived silver nanoparticles was evaluated using TEM observation and molecular dynamics simulation. The TEM observation reveals that the crystal orientation of the sintered silver corresponded to that of the gold substrate. This is considered that the epitaxial layer of silver was formed through in-situ formation of silver nanoparticles from Ag2O paste, an...
