Influence of the preparation history of α-Fe2O3 on its reactivity for hydrogen reduction

Autocatalytic Reduction of Hematite with Hydrogen under Conditions of Surface Control: A Vacancy-Based Mechanism

“…In view of the results of earlier workers (24)(25)(26), ferric and lower iron oxides. The issue also bears on the the increase in conductivity was attributed to an increase use of ferric oxide in catalysis (11,12) and on its potential in the density of oxygen vacancies which results from the as a thermistor (13), a gas sensor (14), and as a photoanode reduction reaction. The results are confined to the lowin solar energy conversion devices (15).…”

<I>In-Situ</I> Kinetic Study of Hydrogen Reduction of Fe<SUB>2</SUB>O<SUB>3</SUB> for the Production of Fe Nanopowder

“…Earlier investigations also reported on the occurrence of simultaneous reduction process of iron oxide. [20][21][22] In subsequent reaction to the completion of reduction, the Fe 3 O 4 ! Fe reduction can be taken as a major reaction leading the whole reduction process.…”

Co-Production of Electricity and Hydrogen Using a Novel Iron-based Catalyst

“…Several other researchers have also investigated the addition of promoters to iron oxide catalysts to enhance its stability and hydrogen productivity. Shimokawabe et al (1979) showed that doping iron oxides with other metals (Cu, Mn, Co and Ni) reduced the iron oxide reduction temperature and increased hydrogen production yields. Urasaki (2005) investigated the influence of Pd and Zr on the redox properties of iron oxide and showed both promoters increased the activity of the iron oxides for hydrogen production (Urasaki et al, 2005).…”
