Abstract:
1. A method of manufacturing a nano-platinum (Pt) catalyst on nano-sized silicon dioxide (SiO 2 ), comprising steps of: (a) adding a powder of SiO (b) processing ultrasonic vibration and high speed agitation to obtain a paste of SiO (c) adding a solution of EG having an electro-catalyst precursor into said paste of SiO (d) processing high speed agitation to obtain a mixed solution; (e) heating said mixed solution at a temperature of 160±10° C. to remove hydrogen and chlorine in said electro-catalyst precursor and to adhere metal catalyst particles in said electro-catalyst precursor to SiO (f) hot-drying said powder of SiO (g) washing said powder of SiO (h) hot-drying said powder of SiO
