The work studies the structural and photoinduced properties of silicon nanoparticles (NanoSi) obtained by plasmachemical and electrolytic techniques and the nickel particles deposited on aluminum oxide film in ultra-high vacuum.
Phenols and the chlorinated and alkylated derivatives are classified as priority pollutants due to the health risk associated with their toxicity. Due to their constant presence in industrial waste and consequently their carcinogenic risk for [...]
2~10 nm sized metal nano-particles were uniformly loaded in porous activated carbon (AC) support and 10~100 nm sized metal nano-particles were completely covered on the surfaces of air flow channels of porous ceramic monolith. Metal [...]
Hydroprocessing is a refinery process of catalytic cracking and hydrogenation of petroleum in order to convert low value heavy hydrocarbons into high value light hydrocarbons and to remove sulphur, nitrogen, oxygen and metals to the [...]
Alkali titanates have been intensively investigated mostly because of their properties. And the interest for transition metal doping of 1D titanate nanostructures is enormous, especially copper. In the present work we report the synthesis of [...]
We have found that Au nanoparticles on Al2O3 (a popular commercially available support material) show surprisingly high activities for CO oxidation when properly prepared [6-11]. Our proprietary catalyst, Au deposited on a ferrite-modified alumina prepared [...]
Hydrogen as a renewable clean energy has attracted a lot attention because of its high heat conversion efficiency and zero carbon emission, while synthesizing highly efficient material for photocatalytic hydrogen production under solar light remains [...]

Recently, studies revealed that noble metal (Au, Ag, Pd) nanoparticles can improve the photoresponse property of TiO2 in the visible region based on the localized surface plasmon resonance (LSPR) effect, and thus enhance the activity [...]
In this paper three-dimensional (3D) titania nanostructures assembled with rutile nanorods have been fabricated via a hydrothermal reaction route. The effects of preparation parameters including the reaction temperatures and the reactant concentrations, on the microstructure, [...]
Amorphous nanoporous chalcogenides (chalcogels) represent a novel class of materials with promising properties for applications as catalysts, gas separation, and heavy metal environmental remediation. In the present work, first-principles molecular dynamics (FPMD) simulations are first [...]
One of the attractive hydride compounds is the borohydride which exhibits high hydrogen content in NaBH4 form (~10.6 wt%). Thus, significant number of experimental research have been devoted to investigate its applicability as a hydrogen [...]
Enzymes are well established as catalysts for various bio-transformations. However, it is difficult to remove the expensive enzymes from the reaction mixtures. Hence, immobilization of enzymes on solid support is a very important step for [...]
SBA-15 has been successfully applied as a support to prepare supported metal catalysts. Nevertheless, Conventional impregnation method cannot assure the incorporation of active species into SBA-15 mesopores. The modification of silica support using ethylene glycol [...]
