Hydrogen generation by ammonia decomposition using Co supported on Mg/La mixed oxide: Effect of calcination atmosphere of support

Podila S., Driss H., Alhamed Y.A., Al-Zahrani A., Petrov L.A., King Abdulaziz University, SA

Generation of COx free hydrogen by ammonia decomposition (AD) is more attractive from practical and economical perspectives compared to other process. Previous studies showed that Ru supported on multi wall carbon nanotubes (MWCNTs) is the [...]

Ammonia Decomposition over Ni Supported on Multi-Wall Carbon Nanotubes: Effect of Surface Functional Groups

Zhang H., Alhamed Y., Kojima Y., Al-Zahrani A., Idriss H., Petrov L., Daous M., King Abdulaziz University, SA

Functional groups on the Multi-Wall Carbon Nanotubes (MWCNTs) surfaces play an important role in anchoring metal ions. Transition metals such as Fe, Co, Ni supported on MWCNTs with surface carboxyl groups have demonstrated an excellent [...]

Carcinogenicity Assessment Using Biosensors: Mitomycin-C As A Case Study

Alhadrami H.A., King Abdulaziz University, SA

This study enabled an empirical assessment of a model carcinogen borne in soil and its potency on human receptors. SOS-lux biosensors had numerous practical advantages over the traditional assays including procedural simplicity, ease of measurement [...]

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 [...]

XRD and SEM studies on annealed nanocrystalline titanium dioxide powder

Babkair S.S., Ansari A.A., Al-Qurashi N.N., King Abdulaziz University, SA

Anatase phase of nanocrystalline (nC) titanium dioxide in photo-catalysis, photo-splitting of water to produce hydrogen and as electrode material in Dye Sensitized Solar Cells (DSSCs)is mostly used due to its higher band gap. However, recent [...]
