Abstract
Methods of sol-gel processing for the preparation of mixed gels and nanoparticles are described. Further, mixed gels and nanoparticles obtained by the method are also disclosed. More specifically, a process for mixture of NiO nanoparticles and Yttria stabilized Zirconia nanoparticles obtained by only one sol-gel process is described.
Claims16
A method of sol-gel processing for the preparation of nanoparticles, comprises the steps of:
- a) preparing a first aqueous solution comprising at least two inorganic metal salts and a doping agent, and preparing a second aqueous solution comprising pectin and mono or disaccharides;
- b) mixing the first and second solutions to form a third solution, at a temperature from about 100-110° C.;
- c) incubating the third solution at an elevated temperature of about 100 to 110° C. for sufficient time in order to gelatinize the third solution to a gelatinized material;
- d) thermal treatment of the gelatinized material from step c) at a temperature of from 500 to 1200° C., in order to obtain a powder of nanoparticles.
