The synthesis and properties of an oxygen reduction catalyst based on a unique 3-dimensional (3D) nitrogen doped (N-doped) carbon composite are described. The composite material is synthesised via a two-step hydrothermal and pyrolysis method using bio-source low-cost materials of galactose and melamine. Firstly, the use of iron salts and galactose to hydrothermally produceiron oxide (Fe₂O₃) mag...

The first efficient and non-precious nanoparticle catalyst for alkene hydrosilylation with commercially relevant tertiary silanes has been developed. The nickel nanoparticle catalyst was prepared in situ from a simple nickel alkoxide precatalyst Ni(O(t) Bu)2 ⋅x KCl. The catalyst exhibits high activity for anti-Markovnikov hydrosilylation of unactivated terminal alkenes and isomerizing hydrosily...

Nanostructured carbon-based materials, such as nitrogen-doped carbon nanotube arrays, Co3O4/nitrogen-doped graphene hybrids and carbon nanotube-graphene complexes have shown respectable oxygen reduction reaction activity in alkaline media. Although certainly promising, the performance of these materials does not yet warrant implementation in the energy conversion/storage devices utilizing basic...

Direct formation of iron phosphate nanoparticles on solid substrates with a narrow size distribution (average diameter = 2.2 nm) has been achieved by a simple spontaneous reaction of ferric chloride and phosphoric acid on hydroxyl-terminated SiO2/Si substrates. Single-walled carbon nanotubes (SWNTs) are grown in high yield from the synthesized iron phosphate nanoparticles by thermal chemical va...

Nanoparticles are being intensively investigated because of their unique optical, electrical and catalytic properties which make them a potential material for utilization in the field of medicine electronic and environmental issues. This paper is concerned with the removing a heavy metal, Chromium, from its aqueous solution by Iron oxide nanoparticle filtration. Solutions of varying chromium co...
