TL;DR: In this paper, a three-stage mechanism for the reduction of various iron oxides in hydrogen and carbon monoxide atmospheres has been investigated by temperature programmed reduction (TPR H2 and TPR CO ), thermo-gravimetric and differential temperature analysis (TG-DTA-MS), and conventional and in situ XRD methods.

TL;DR: In this article, the influence of silver and gold addition on the activity and physicochemical properties of supported Cu/CrAl3O6 catalysts was investigated. And the most active was 20.5 wt.% for support CrAl 3O6 alone, supported copper and gold and silver promoted copper supported catalysts.

TL;DR: In this article, the authors focused on the physico-chemical and catalytic properties of Co/SiO 2 catalysts and showed that those catalysts in which cobalt was chemically bonded with silica show worse reducibility as a result of strongly bonded Co-O-Si species formed during high temperature oxidation.

TL;DR: In this paper, the physicochemical properties of ZnO, Al 2 O 3, ZnAl 2 O 4, AlO 2.5, and Zn 2 AlO 3.5 were determined for methanol synthesis.

TL;DR: In this paper, the influence of the preparation procedure and Ni content on partial oxidation of methane to synthesis gas was investigated, and two different Ni-containing zeolite catalysts were prepared by two different methods: a conventional wet impregnation method (NixAlBEA series), in which Ni ions were introduced mainly in the extra framework position and a two-step postsynthesis method, which allowed incorporating Ni ions into the Zeolite framework.
