The thermal decomposition of platinum acetylacetonate and platinum nanoparticles forming upon the decomposition are studied in-situ via X-ray diffraction (XRD) and Raman spectroscopy, termal gravimetric analisys, scanning (SEM) and transmition electronic microscopy (TEM). The experiments are made at the rates of heatings of 1 and 5 K/min. The comprehensive analysis of SEM, TEM and XRD data evidences the formation of coarse Pt particles upon the thermal decomposition, whose sizes vary as ~60--160 nm, and which are in turn composed of nanoparticles with dimensions of 1.9 and 4.1 nm for 1- K/min- and 5 K/min-rates of heating, respectively. This means that the desirable average size of nanoparticles during theirs synthesis can be achieved through a simple tuning of the rate of heating of acetylacetate thermal decomposition.
