Catalytic activities of sputtered p-type Cu2O electrode in connection with TiO2 thin film for dye degradation

Wu K.R., Hung C.H., Yeh C.W., Sun J.C., Hsu C.J., National Kaohsiung Marine University, TW
In this study, a p/n-type photoelectrocatalytic (PEC) cell was used to enhance the photocatalytic (PC) and PEC activities towards the degradation of methylene blue (MB) solution under ultraviolet (UV) irradiation. The PEC cell consists of [...]

Novel supported catalytic materials based on multiwalls carbon nanotubes

Koltypin Y., Savilov S.V., Gedanken A., Landau M.V., Bar-Ilan University, IL
We present a method that allows proper control of the nanoscale curvature of the external surface in multiwall carbon nanotubes (MWCNT) and shown its effect on the properties of Ni/MWCNT catalyst. After removal of residual [...]

Natural Gas in Syngas Conversion Over Nanosize Catalysts

Neiva L.S., Simões A.N., Oliveira J.B.L., Andrade H.M.C., Gama L., Federal University of Campina Grande, BR
This work has as aim the development of Ni catalysts supported in α-Al2O3/ZnO, Al2O3/Fe2O3 and Al2O3/ZrO2 to be applied in to catalytic reaction of the steam reforming of the methane. The Al2O3/ZnO, Al2O3/Fe2O3 and Al2O3/ZrO2 [...]

Palladium Quantum Dots Sensitized TiO2 Nanotube Arrays for Enhancing Photoelectrocatalytic Hydrogen Generation

Gong J.J., Lin C.J., Xiamen University, CN
In order to further enhance photoeletrocatalytic reactivity, it is desirable to develop a facile and effective technique to obtain high quality Pd@TNTAs with homogeneous dispersion and small enough particle size down to few of nm [...]

Oxygen Reduction Reaction Enhancement of PdCo/C Electrocatalysts Driven by Oxidation Treatment

Wang K-W, National Central University, TW
One of the key issues for polymer electrolyte membrane fuel cells (PEMFCs) is to reduce or replace expensive Pt cathode catalysts. Although the development of non-Pt, such as Pd-Co catalysts for the oxygen reduction reaction [...]

Pt-Au Core/Shell Nanorods: Preparation and Applications as Electrocatalysts for Oxygen Reduction Reaction

Liu C-W, National Central University, TW
Nanostructured materials have been studied intensively due to their board potential applications in the energy field. A great deal of effort has been devoted to developing high efficient nanocatalysts for oxygen reduction reaction (ORR). In [...]

Thermo Catalytic decomposition of methane on Ni/SiO2 catalyst into pure hydrogen and carbon nanotubes

Sarashwat S., Pant K.K., IIT Delhi, IN
The current methods of producing hydrogen are based on steam methane reforming (SMR), coal gasification, electrolysis, biomass gasification and thermochemical processes A comparison between the cost of hydrogen production from renewable energy, and fossil sources, [...]

Design and Application of Novel Nano Drilling Fluids to Mitigate Circulation Loss Problems during Oil Well Drilling Operations

Mostafavi V., Ferdous M.Z., Hareland G., Husein M., University of Calgary, CA
Nano-fluids have recently attracted attention in the petroleum industry as potential solutions to several shortcomings of conventional drilling fluids. Drilling fluid is in charge of numerous functions during the drilling operation including transport of cuttings [...]

The Separation of Hydrocarbons from Sand Using Ionic Liquids

Painter P., Miller B., Lupinsky A., Williams P., Penn State University, US
The problem that this work addresses involves the separation of oil, bitumen or tar from sand or other types of mineral matter. The processes presently used to separate or extract hydrocarbons from sand are expensive, [...]

Next Gen Large Area Lighting: HIDs, Robotics and Energy Efficiency

Davis G., Lumetric, US
Lumetric has reinvented lighting for large areas, combining advanced energy control features with high output lamps to create the brightest, most energy-efficient lighting solution, generations ahead of the alternatives. Simple to install and easy to [...]
