Influence of the thermal processing and doping on LaMnO3 and La0.8A0.2MnO3 (A = Ca, Sr, Ba) perovskites prepared by auto-combustion for removal of VOCs
(MDPI, 2022)
Single-phase oxygen stoichiometric LaMnO3 and doped La0.8A0.2MnO3 (A = Ca, Sr, Ba) perovskites have been prepared by a simple one-step auto-combustion method. Cation-deficient LaMnO3+ and La0.8A0.2MnO3+ were obtained by ...

(ELSEVIER, 2006-09-25)
A simple microwave-assisted extraction and partitioning method (MAEP) using water-acetonitrile and n-hexane for desorption and simultaneous partitioning, respectively, together with gas chromatography (GC) was studied to ...
Bulk and Surface Structures of V2 O5 /ZrO2 Systems and Their Relevance for o -Xylene Oxidation
(American Chemical Society, 2002-04)
Zirconia-supported vanadium oxide systems, with V2O5 loadings ranging from V/Zr ) 0.033-0.270 atom ratios (0.2-2 monolayers), were prepared by impregnation of a porous ZrO2 substrate with ammonium metavanadate solutions. ...
