In this study, iron nanoparticles (FeNPs) were synthesized by green route under microwave irradiation. Terminalia arjuna bark extract was used for synthesis, which acts as reducing and stabilizing agent. The synthesized FeNPs were characterised by UV-Visible spectra, X-ray diffraction (XRD), scanning electron microscopy (SEM), Fourier transform infrared spectra (FT-IR), BET surface are...

The detection probability of visible light reconnaissance equipment is one of key indexes to assess the performance of the system. The detection probability is determined by many factors, such as atmospheric visibility, target-background contrast, target size and distance, solar elevation angle etc. Based on the detection probability model of the visible light reconnaissance equipment to gain t...

a novel zr,ce-tio2/sio2 nanocomposite thin film was successfully prepared with various amounts of zr4+ and ce4+ as codopant ions for self-cleaning applications. a thin film was coated on a tile substrate by dip-coating and porous zr,ce-tio2/sio2 was obtained after heat treatment for 2 hours at 500 °c. the sem images and xrd pattern showed that the optimum amount of doping ions in relation to ti...

A novel visible light-driven photocatalyst film, MoS₂/Ag/TiO₂, was synthesized on a glass-fiber membrane. The composite catalyst film had a multi-layer structure with Ag as nanoconjunctions between the MoS₂ and TiO₂ layers. The catalyst film performed well for both photocatalytic hydrogen production and organic degradation in a two-chamber photo-reactor under either solar or visible light. Hydr...

AM-6 with high intensity visible light absorption at 400-800 nm was synthesized via a hydrothermal route in the presence of F(-) ions. Structure characterization and DFT calculations indicate that the unusual optical properties originate from the connection of octahedral VO(6) wires with distorted tetrahedral VO(4) units, which are stabilized in the framework of AM-6.

We theoretically and experimentally demonstrate that carbon self-doping could induce intrinsic electronic and band structure change of g-C(3)N(4)via the formation of delocalized big π bonds to increase visible light absorption and electrical conductivity as well as surface area and thus enhance both photooxidation and photoreduction activities.

Visible-light-activated photochemical degradation against VOCs in indoor air using TiO 2 nanoparticles encapsulated crystal violet.

Recyclability is an important aspect for heterogeneous photo-catalysts. Ease of recovery and stability of the photo-catalyst in terms of efficiency over the number of cycles are highly desired and in fact it is ideal if the efficiency is constant and it should not decrease marginally with each cycle. Presented here is a seminal observation in which the photocatalytic activity is shown to improv...

The fabrication of functional metamaterials with extreme feature resolution finds a host of applications such as the broad area of surface/light interaction. Nonplanar features of such structures can significantly enhance their performance and tunability, but their facile generation remains a challenge. Here, we show that carefully designed out-of-plane nanopillars made of metal-dielectric comp...
