Web31 Jan 2011 · The oxidation of tin layers deposited onto alumina substrates is investigated with the aim to identify the different steps of the process and obtain information on the sample homogeneity, phase segregation, and degree of oxidation. WebAbstract: In the present study, redox (CeO 2, SnO 2, Pr 6 O 11 and Mn 3 O 4) and non-redox (Gd 2 O 3, La 2 O 3 ZrO 2 and HfO 2) metal oxides were successfully synthesised using the EDTA–citrate complexing method and tested for soot oxidation activity.The characterization of the metal oxides is carried out using FTIR, XRD, BET surface area, pore volume …

Web9 Oct 2024 · In summary, XRD, BET, STEM-EDXS, and CO-chemisorption confirm the successful preparation of Pd-decorated SnO 2 nanoparticles. These particles consist of Pd clusters that are in close contact and well-dispersed on Sn in an oxidized state, and between 3–6 nm mean Pd cluster sizes by CO-chemisorption for all Pd loadings. 3.2. Sensing Web1 day ago · The effect of the vacuum repressing temperature on the Ag-SnO 2 material containing CuO additive was systematically investigated under a constant pressure of 200 MPa. The results showed that the relative density of the material repressed at 800 °C for 10 min can be increased to as high as 99.75%. WebThe mass current density of PdSn/SnO x reached 3.2 A mg Pd−1 at 0.85 V vs. RHE in 1 M KOH solution, which is 3.2 times higher than that of the commercial Pd catalyst. More importantly, these PdSn/SnO x core/shell nanoparticles exhibit enhanced stability compared with the commercial Pd catalyst. maleficent game app
