Enter just an element symbol to show the common and uncommon oxidation states of the element. 元素中的第一个字符使用大写字母,第二个字符使用小写字母。例子:Fe, Au, Co, Br, C, O, N, F。 你可以用小括号()或括号[ ]。 What is an oxidation state? The oxidation state or oxidation number ...
During primary oxidation, the alloy developed an inner layer of Ni(Al, Cr)2O4 spinel and the outer scale contained discrete particles of NiO and Cr2O3. When steady-state conditions were established, the inner spinel was replaced by a yttrium-modified layer of α-Al2O3. Under steady-state...
5a and b. In each stage, the iron-based OC underwent a shift in oxidation state as the reaction performed changed according to the following sequence: CLC (Fe3+→Fe2+), dry reforming of methane (Fe2+→Fe0), steam splitting (Fe0→Fe3O4), and air oxidation (Fe3O4→Fe3+). Their ...
into several layers,from outer to inner the layers are composed by TiO2 enriched layer,TiO2 and Al2O3 enriched layer,TiO2,Al2O3 and pores enriched layer,and Al2O3 enriched layer.Generally the oxide scale is grown by the outward diffusion of Al3+ and Ti4+ and the inward diffusion of ...
Kinetic modeling of the total oxidation of propane over CuO-CeO2/γ-Al2O3 The total oxidation of propane is studied by means of steady-state experiments over a CuO–CeO 2/γ-Al 2O 3 catalyst at propane inlet partial pressures of ... MP Heynderickx,JW Thybaut,H Poelman,... - 《App...
Chemically, it is a gas-to-gas reaction, meaning that the fuel has to be in the gaseous state in order to react with the oxidizer, which is already in the gaseous state. This is a very important concept because liquids and solids do not burn in an open flame, only their vapors do....
