Abstract:
A new microwave-assisted gel-combustion synthesis in self-propagating mode was developed for the deposition of adhesive metal nanoparticles on ceramic substrates. Pt particles with diameters less than 10 nm uniformly distributed on corundum foams were prepared by the fast and reliable combustion method with no additional calcination or reduction steps. The results are rationalized in terms of the exothermic combustion of the glycerol-chelated metal precursor and subsequent in situ reduction assisted by the formed amorphous carbon absorbing microwave radiation.
