Abstract
This disclosure relates to solvothermal synthesis-based method for nanoparticles production. In conventional methods, precursor loading is limited to below the solubility limit of the precursor and results in low throughput and low yield. The disclosed method increases metal precursor loading up to the solubility limit of the metal precursor solution. The method includes pouring the pH modifier dropwise into the metal precursor solution with vigorous stirring, resulting in formation of metal hydroxide solution. The concentration of metal precursor solution is maintained in range of 0.025 M to 2 M, pH in range of 9 to 12, and stirring speed of 800-1200 rpm. The metal hydroxide solution is heated and temperature of the reaction in the range of 25° C. to 400° C. is maintained with aging time in the range of 6 to 24 hours to obtain the nanoparticle slurry resulting production of high yield and high throughput nanoparticles.
