Patent ID: 8168558

Claim:
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 2 into a solution of ethylene glycol (EG), wherein said powder of SiO 2 is a powder of SiO 2 having a scale of nanometers; (b) processing ultrasonic vibration and high speed agitation to obtain a paste of SiO 2 ; (c) adding a solution of EG having an electro-catalyst precursor into said paste of SiO 2 ; (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 2 and thus to obtain a powder of SiO 2 ; (f) hot-drying said powder of SiO 2 in vacuum with EG being removed; (g) washing said powder of SiO 2 by using de-ionized water with remained EG being removed; and (h) hot-drying said powder of SiO 2 in vacuum with de-ionized water being removed.
