Formation of #x03B1;-MoO3 (010) micropalettes for nanoarchitecture

摘要

α-MoO3 micropalettes with high-quality surface have been formed by annealing of intermediate molybdenum oxide at T = 650°C in air. The intermediate molybdenum oxide was prepared by thermal decomposition of molybdenum formate at T = 450°C under oxygen deficiency. The chemical composition, structure and micromorphology of intermediate products and α-MoO3 micropalettes have been examined with XRD, SEM, AFM, TG/DSC and IR spectroscopy. The results indicate the formation of α-MoO3 micropalettes with ∼50 μm length, ∼10 μm width and ∼600 nm thickness, developed (010) crystal plane and high-quality flat surface.
