Controlled Synthesis of Subnano Pd Cluster Catalysts by Fine Tuning of Dendrimers

Mizugaki T., Kibata T., Maeno Z., Mitsudome T., Jitsukawa K., Kaneda K., Osaka University, JP
We recently succeeded in the fine control of the Pd cluster sizes in wide range using the fifth generation poly(propylene imine) (PPI) dendrimers. Preorganization of Pd ions within the PPI dendrimer with butanediamine core(G5-C4) and [...]

Peptide Nanoparticle Catalysis

Heller M.J., Cheung M., Takahashi T., University of California San Diego, US
Improved catalysis for more efficient chemical processing, biomass conversions and water oxidation-hydrogen production will be important for achieving new clean technologies. Our research work involves a novel approach to produce catalytic mechanistic properties in synthetic [...]

Novel Hierarchically Ordered Porous Vanado-Silicate Nanocomposites for the Application in Industrial Catalysis

Howard M., Whittle J., Zhang F., Zhao D., Sen T., University of Central Lancashire, UK
A novel hierarchically ordered porous vanado-silicate nanocompsoites were fabricated with isolated vanadium species with well dispersed state in the porous martrix for the oxidation of bulkier organic molecules i.e cyclooctene for the selective production of [...]

Advances (and limits) in photocatalytic building materials

Diamanti M.V., Politecnico di Milano, IT
Titanium dioxide has often been indicated as emerging technique for environment depollution, specially in urban environments. It can be easily added to building materials, such as concrete or mortar elements, or as coating to any [...]

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 [...]
