| description | Organosol logam aurum dan platinum telah disintesis secara in-situ dengan kehadiran ENR-50 melalui kaedah penurunan kimia menggunakan 2-propanol sebagai agen penurun. Organosol yang setara juga telah disediakan melalui teknik pemindahan fasa dari air ke toluena bagi partikel yang telah terbentuk dalam pelarut akueus melalui penurunan ion logam oleh natrium borohidrida (NaBH4).
Gold and platinum metal organosols were synthesized in-situ in the presence of ENR-50 via chemical reduction method by employing 2-propanol as the reducing agent. A similar organosols was also prepared via water to toluene phase transfer technique of the preformed particles in aqueous solution by sodium borohydride (NaBH4) reduction of metal ions. For the in-situ preparation, the finest gold and
platinum nanoparticles in terms of size, dispersability and stability can be obtained by varying the metal ions concentrations and reaction temperatures.
