Synthesis of Visible light Nanocomposites for H2 Production

Hussein A.M., Shende R.V., South Dakota School of Mines & Technology, US

Visible light active nanocomposites were synthesized by the sol-gel method using non-ionic surfactant as a template. Cr-doped ZrO2-modified coupled ZnO/TiO2 composite was thoroughly characterized for surface area, crystal phase, microstructure, elemental identification and band gap [...]

A hierarchical carbon nanofiber-In2S3 photocatalyst with well controlled nanostructures for highly efficient hydrogen production under visible light

Gao P., Li A., Liu Z., Tai M., Liu Z., Sun D.D., Nanyang Technological University, SG

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 [...]

Synthesis and Characterization of a Novel Palladium Nanostructured Ensemble Supported in Anodized Alumina Membranes for Hydrogen Sensing Applications

Méndez-Colberg H.G., Martínez-Iñesta M.M., University of Puerto Rico, Mayaguez Campus, US

A Pd/Anodic alumina membrane (AAM) ensemble was formed by using Solid State Reduction. The ensemble consisted of Pd thin films on both sides of the AAM with connecting nanowires as evidenced with Scanning Electron Microscopy [...]

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 [...]

Physical properties of multilayer thin films of Ti-V and their hydrides studied by ion beam analysis methods

Drogowska K., Flege S., Becker H.-W., Tarnawski Z., Zakrzewska K., Balogh A.G., AGH University of Science and Technology, PL

A wide variety of characterization techniques were used to determine the properties of titanium, titanium oxides and vanadium oxide thin film multilayers with different thicknesses, for the as-deposited state as well as under different levels [...]

BioGenerator – a Novel Bio-Technology for the Conversion of Hydrogen to Electricity

Karamanev D., University of Western Ontario, CA

One of the promising applications of the H2-to-electricity converters is in the field of power smoothing and storage. The technologies currently considered for smoothing and storage have certain problems. The use of hydrogen as a [...]

Properties of nonpremixed ammonia-substituted hydrogen-air flames

Joo J.M., Um D.H., Kwon O.C., Sungkyunkwan University, KR

The effects of ammonia (NH3) substitution on the extinction and nitrogen oxide (NOx) emissions of nonpremixed hydrogen (H2)-air flames at normal temperature and pressure were experimentally studied to evaluate the potential of partial NH3 substitution [...]
