سنتز و شناسایی نانوذرات اکسید مولیبدن (vi)

in solvo-hydrothermal method, xrd pattern was indicated presence of intermediate of ammonium octatmolybdate and ammonium tetramolybdate, which were changed to stble phase of ?-moo3 annealing. sem images were indicated nanoparticle with semispheical morphology and tem image was demonstrated nanoparticles with a diameter size of 25nm. also in impregnate method. the xrd pattern was shown high crystalline moo3 phase.tem image was shown hexagonal array of uniform cahnnels of al-sba-15 with a diameter of 7nm tath were ratained after impregnate and calcination. the n2 adsorption -desorption isotherms. were shown decrease of surfce area and pore size after immobiliztion. infrared spactra were indicated change in peaks ntensity and crate of new vibration at support when mo introdec. the molybdenum loading were obtained %17.15 on sba-15 and %11.5 on al-sba-15 supports using icp analysis.
