Metal oxide nanoparticles MoO2 with tremella-like morphology have been synthesized and characterized. The solvothermal synthesis method is a new procedure starting from MoO3 mixed with ethylenediamine and hydroquinone as reducing and assisting agents, respectively. Characterization by powder XRD and TEM microscopy made possible to estimate that the nanosheets have ca. 12nm and aggregate to form tremella-like...
Nano-sized crystals of maghemite iron oxide (γ-Fe 2 O 3 ) were synthesized onto the surface of NaY-zeolite crystals by immobilizing a polynuclear iron complex [Fe 4 O 2 (O 2 CCH 3 ) 7 (bpy) 2 ](ClO 4 ) (bpy=2,2′-bipyridine) and subsequent calcination of the material in oxygen. Superparamagnetic γ-Fe 2 O 3 particles...
