Industrial and other anthropogenic activities lead to increase in persistent organic pollutants (POPs) natural water bodies. POPs are harmful not only the aquatic ecosystem but also human health. Researchers around globe have been working develop efficient, cost-effective, environmentally-friendly methods for treatment of contaminated waters. The chapter basically focuses on removal by catalyti...

Diamond like carbon (DLC) film was grown by hot filament chemical vapor deposition (HFCVD)technique. In the present work, we investigated the quality of the DLC films groew on the substratesthat were coated with various metal nanocatalysts (Au and Ni). A combination of CH4/Ar/H2 rendersthe growth of carbon nanostructures technique (diamond like carbon). The utilized samples werecharacterized by...

Many applications of nanotubes and nanowires require controlled bottom-up engineering of these nanostructures. In catalytic chemical vapor deposition, the thermo-kinetic state of the nanocatalysts near the melting point is one of the factors ruling the morphology of the grown structures. We present theoretical and experimental evidence of a viscous state for nanoparticles near their melting poi...

Microbially generated or supported nanocatalysts have potential applications in green chemistry and environmental application. However, precious (and base) metals biorefined from wastes may be useful for making cheap, low-grade catalysts for clean energy production. The concept of bionanomaterials for energy applications is reviewed with respect to potential fuel cell applications, bio-catalyti...
