The present invention relates to catalysts of iron and chromium with a platinum promoter for use in water-gas shift reactions, both at low temperatures (LTS) and at high temperatures (HTS). Their characteristics of higher activity due to the addition of Pt compared to the conventional catalysts make them superior to the commercial catalysts in the same operating conditions. Because precursors of the active phase (Fe.sub.3O.sub.4) are obtained in greater quantity per unit area, it was possible to prepare catalysts that are more promising with a smaller surface area.

An electrically conductive member of the present disclosure includes a base member containing chromium (Cr), and a first layer provided on a surface of the base member and containing chromium(III) oxide (Cr.sub.2O.sub.3). The first layer also contains titanium (Ti).

The present invention relates to a method for preparing uniform metal oxide nanoparticles. According to the preparation method of the present invention, it is possible to maintain the temperature and pressure inside the reactor in a stable and constant manner by removing water generated in the reaction step for forming metal oxide nanoparticles. Thus, the uniformity of nanoparticles formed is increased, and the reproducibility between batches can be increased even in a repeated process and and a large-scale reaction. Therefore, the preparation method of the present invention can be used to synthesize uniform nanoparticles reproducibly in large quantities.
