The mechanism of reduction of iron oxide by hydrogen
TL;DR: In this paper, temperature-programmed reduction was used to characterize precipitated iron oxide samples and two-stage reduction was observed: Fe2O3 was reduced to Fe3O4 and then reduced to metallic Fe.

Influence of metal loading on the reducibility and hydrogenation activity of cobalt/alumina catalysts
Wei Jye Wang,Yu Wen Chen +1 more
TL;DR: In this article, a series of Co/Al2O3 catalysts with various metal loadings were prepared by incipient-wetness impregnation and the reducibility of cobalt oxide in these samples was investigated by the temperature-programmed reduction technique.

The mechanism of reduction of cobalt by hydrogen
Hsin Yu Lin,Yu Wen Chen +1 more
TL;DR: In this paper, temperature-programmed reduction (TPR) was used for two-stage reduction of cobalt catalysts supported on silica, and the activation energies for the two reduction steps were 94.43 and 82.97 kJ−mol −1, respectively.
