Nanoporous thin film fabrication via magnetron sputtering and O2 plasma ashing process

Han S.H., Jang S.W., Hwang S., Hwang S.H., Hwang S., Hwang S.H., Korea Institute of Science and Technology, KR

We report a new method of fabricating nanoporous catalytic thin films. In the first step, metal–carbon thin films were prepared by reactive magnetron sputtering, using various metallic targets (Au, Ag, Pt, Cu, Ni, Ti) as [...]

Computational study of structural dependence of catalytic properties of Pt-Ru nanoalloy catalysts

Prasai B., Petkov V., Central Michigan University, US

Metal nanoparticles (NPs), composed of single-type metals and multiple-type metals, have attracted a great deal of interest in the research community since such NPs are key components in many useful applications such as catalytic, magnetic [...]

Catalytic Performance Enhancement by Low Temperature Plasma Treatment

Miley G.H., Srivastava S.N., Chen G., UiUC/NPL Associates, US

Polymer Electrolyte Membrane (PEM) fuel cell electrocatalysts are composed of noble metals (e.g. platinum), which are scarce and expensive. A simple plasma-surface modification method is described to increase the performance of PEM fuel cell catalytic [...]

Development of a hydroprocessing catalyst containing Boron and Nano-boron compounds

Yonel-Gumruk E., Meric Kartal Berker A., Özcan O., Nilgün Akin A., Turkish Petroleum Refineries Corporation, US

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 [...]

Uniformly Distributed Metal Nano-particles in Various Sized Porous Catalytic Supports by NPP Process

Lee C., Lee J-H., Lee C., Lee J-H., Kang B.K., Kaji H., Hayashi M., Koh S.K., GL Materials, KR

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 [...]

Ammonia Decomposition on Carbon Supported Cobalt Catalyst

Zhang H., Alhamed Y.A., Petrov L., Kojima Y., King Abdulaziz University, SA

Liquid ammonia has both high energy density and high hydrogen storage capacity which makes it suitable for on-board generation of COx free hydrogen by catalytic ammonia decomposition (AD). Cheap catalysts based on cobalt were considered [...]

From Biogas To Syngas Over Ni Incorporated Ca and Mg Based Hydrotalcite-Like Catalysts

Yasyerli S., Topaloglu G., Dogu G., Gazi University, TR

Catalytic transformation of methane-carbon dioxide mixture, produced through anaerobic digestion of organic waste, to syngas is a promising route for the production of chemicals and fuels from biogas. Dry reforming of methane is expected to [...]
