A Review of the Center for Fluorinated Functional Materials

Sun H., University of South Dakota, US

Center for Fluorinated Functional Materials was established in July 2017 with a significant effort from the State of South Dakota. The mission of this center is to build a self-sustained discovery-based research center that boosts [...]

Graphene decorated metal nanoclusters as an effective novel catalyst for improving the hydrogen storage behaviour of MgH2

Ramesh A., Sterlin Leo Hudson M., Takahashi K., Central University of Tamil Nadu, IN

Abstract: High volumetric and gravimetric hydrogen density in MgH2 motivates significant research attention over the recent years to make it as a viable hydrogen storage material for fuel cell applications. However, the high thermodynamic stability [...]

Optimization of Catalyst Nano-structures through Alloying and De-alloying Process—Research on Ag-Co catalyst for Catalytic Oxygen Reduction in Alkaline Media

Jiang R., U.S. Army Research Laboratory, US

Optimization of particle size and particle’s nano-structure at the atomic level can precisely and effectively tune catalytic properties of materials, and enabling enhancement in both catalytic activity and stability. We synthesized a highly active and [...]

CO2 reforming of CH4 by the combination of dielectric barrier discharge plasmas and zeolite catalysts

Kim K.S., Nguyen H.H., Kangwon National University, KR

Dry reforming of two green-house gases (CH4 and CO2) to convert to syngas (mixture of CO and H2) has gained deep research interests lately. Several technologies were proposed to convert the CO2 and CH4, such [...]

Synthesis and characterization of carbon nanotubes by catalytic decomposition of acetylene with Fe/Co/MgO, Co/Zn/Al and (C5H7O2)3Mn/Al as catalysts

Dikio E.D., Vaal University of Technology, ZA

We report our studies on the effect of various catalysts in the synthesis of carbon nanomaterials. The as-prepared carbon nanomaterials were characterized by Raman spectroscopy, high resolution transmission electron microscopy and X-ray diffraction. The catalysts [...]

Advanced Catalysts for Fuel-Flexible Fuel Cells

Breit J., Fleckner K., Grant Norton M., Ha S., Marin-Flores O., Neylon M.K., Washington State University, US

In commercial aviation, a concept called the more electric airplane (MEA) will allow greater fuel efficiency by substituting hydraulically and pneumatically driven systems by those based on electrical energy. The increased electrical power demand in [...]

NanoZeolites – small particles, small pore, big impact! Porous nanoparticles for environmental applications

Daniell W., Kohl A., Sauer J., NanoScape AG, DE

NanoScape has developed hydrothermal synthesis techniques which allow nanocrystalline, porous aluminosilicates (NanoZeolites) to be manufactured, currently on a 100kg p.a. scale. A range of NanoZeolites are available with pore sizes ranging from 3A to 100A. [...]

Two-nozzle flame synthesis of Pt/Ba/Al2O3 for NOx storage

Baiker A., Büchel R., Pratsinis S.E., Strobel R., ETH Zürich, CH

A novel two-nozzle flame spray pyrolysis (FSP) process is presented for one-step preparation of Pt/Ba/Al2O3 particles for NOx storage-reduction (NSR) catalysts. These storage catalysts are of particular interest for mobile engines operating under lean conditions [...]
