Cycling runs of MO decolourisation using 1.50 mol% Fe-doped CeO2film at pH 5 of MO solution. Full size image PL spectra of CeO2at differrent amounts of iron doping level. Full size image Fluorescence spectra of a TA–OH·solution generated by 1.50 mol% Fe-doped CeO2under visi...
In this study, the early stage sintering mechanisms of undoped and Fe-doped CeO2 were investigated, based on two sintering models. We confirm that pure CeO2 exhibits volume-diffusion controlled sintering, while a viscous flow mechanism dominates the early stage sintering of Fe-doped CeO2. 展开 ...

Fe/CeO2metamitronsol-gelGd3+-doped titania nanoparticles have been synthesized via acidic hydrolysis of Gd3+ and Ti4+ organic precursors. The resulting products were characterized by X-ray diffraction, transmition electron microscopy and diffuse reflection spectra. Experimental results indicated that Gd3+...
The Sm‐doped Fe2O3/CeO2 is desirable for chemical looping hydrogen generation (CLHG) owing to its satisfactory oxygen ion conductivity, and the reactivity of Fe2O3/Ce0.8Sm0.2O1.9 (FSDC20) is the highest among the Sm‐doped Fe2O3/CeO2 oxygen carriers with different Sm‐doping amounts....
In this work, Fe3+ doped CeO2 nanoparticles were initially prepared and tested for catalytic activity towards CH4 combustion. Systematic sample characterizations indicate that our nanoparticles were exposed by highly energetic facets (200), which yielded an excellent catalytic performance and thermal ...
