The deposition-precipitation of platinum was investigated using two different platinum precursors chloroplatinic acid and ammonium tetrachloroplatinate. While H2PtCl6 did not allow a deposition-precipitation of platinum, a high deposition of platinum could be obtained using (NH4)2PtCl4 in defined conditions. 

Solubility tests in absence of Ti02 were first performed with a lO M solution of platinum prepared from an ammonium tetrachloroplatinate salt. However, upon mixing NaOH and lO M (NH4)2PtCl4 no precipitation was initially observed. At room temperature, the formation of a precipitate becomes nonetheless detectable after 24 h stirring. After 48 h precipitate was still forming. In m effort to obtain a complete precipitation in a reasonable time, an attempt was made to hydrolyze at 60°C. At this temperature, precipitate formation... 

Tsang et al. [26] described the use of Ft nanoparticles (average size 5nm) encapsulated in porous silica aerogel coating (5% of metal), and then deposited on conventional y-alumina as a composite catalyst for butane oxidation (Fig. 5.6). Preparation of the material was carried out from a microemulsion obtained by using ammonium tetrachloroplatinate(ll), cetyltrimethylamonium bromide in a toluene/water mixture, and then the reduction of platinum anion was accom-...
