Oxidative dehydrogenation of n-butene to buta-1,3-diene with novel iron oxide-based catalyst: Effect of iron oxide crystalline structure

Gold-Iron Oxide Catalyst for CO Oxidation: Effect of Support Structure

Gold-iron oxide (Au/FeOx) is one of the highly active catalysts for CO oxidation, and is also a typical system for the study of the chemistry of gold catalysis. In this work, two different types of iron oxide supports, i.e., hydroxylated (Fe_OH) and dehydrated iron oxide (Fe_O), have been used for the deposition of gold via a deposition-precipitation (DP) method. The structure of iron oxide has...

Catalytic oxidative dehydration of glycerol over a catalyst with iron oxide domains embedded in an iron orthovanadate phase.

An embedded catalyst for the oxidative dehydration of glycerol, featuring iron oxide (FeO(x)) domains on the surface of an iron orthovanadate (FeVO₄) phase, is developed. Catalytic reactions are conducted in a fixed-bed reactor at 300 °C with a feed composition N₂/O₂/H₂O/glycerol=66.6:1.7:30.3:1.5. Catalytic results show that the catalyst exhibits a better performance than an FeO(x) catalyst pr...

Chemical Dynamics of Monodispersed Iron Oxide Nanoparticles

This study is comprised of the synthesis and characterization of uniform fine particles of iron oxide in different shapes and sizes. Varying amounts of iron (III) chloride and sodium dihydrogen phosphate was heated at 98 oC for various periods, following the forced hydrolysis method. Scanning electron microscopic analysis showed that the shape and size of the precipitated particl...

Improve Synthesis of Iron Oxide Nanorode with Hydrothermal Method

Maghemite and magnetite nanoparticles and nanorode are now losing interests in the field of nanobiotechnology and pharmaceutical for their applications. This paper reports on a hydrothermal process for the synthesis of Fe2 O3 in the γ-phases nanorodes, when the hydrothermal temperature was 100 ̊ C. The uniqueness of the method lies in the use of ferrous ammonium sulphate, hexamine was added as t...
