TL;DR: In this article, it was concluded that copper-ammine complexes held on the surface of the zirconia support exist in three different states, viz., isolated and clustered copper(II) ions and tetraamminecopper (II) nitrate.

TL;DR: In this paper, the influence of the preparation history of α-Fe2O3 on its reactivity has been investigated in the context of hydrogen reduction of the metal ion Cu2+, Ni2+, and Ti4+ in a stream of oxygen, air or nitrogen at temperatures of 500-1200°C for one hour.

TL;DR: In this article, the authors used Ni/MgO catalysts prepared by impregnation under various conditions were used for methanation of carbon dioxide, and were characterized by UV/VIS diffuse reflectance spectroscopy and temperature-programmed reduction.

TL;DR: In this paper, a surface phase diagram of the catalyst was tentatively presented as a function of copper loading and calcination temperature, based on the results of ion exchange between the hydroxyl hydrogens on a silica surface and tetraimmine copper (II) ions.

TL;DR: In this paper, a steam reforming of methanol CH 3 OH + H 2 O = CO 2 + 3H 2 was carried out over a variety of catalysts which contained various amounts of copper loaded on silica.
