Platinum containing chalcogenides seem to have bright potential due to the special electrical and catalytic properties stemming from platinum combined with the semiconductor ones of chalcogenides. In this work, a set of synthesis were designed in order to know the influence of different reaction parameters such as temperature, amount of reactants and also different kinds of capping agents on the growth or formation of such nanostructures. The characterization results suggest that a ternary nanostructured chalcogenide system containing two noble metals (Platinum and Silver) was successfully synthesised by using OlAm as capping agent at 120ºC by means of cation exchange reactions. Furthermore, the composition of this ternary is assumed to be Ag3PtSe2. As described through this work, the variation on the previously mentioned reaction parameters allows modifying the morphology and composition of this ternary system. Additionally, the possibility of synthesizing nanostructured binary platinum selenide has also been explored
