发明人：STROUSE GEOFFREY FIELDING; GERBEC JEFFREY A; MAGANA DONNY
权利人:UNIV CALIFORNIA
摘要:A method for synthesis of high quality colloidal nanoparticles using comprises a high heating rate process. Irradiation of single mode, high power, microwave is a particularly well suited technique to realize high quality semiconductor nanoparticles. The use of microwave radiation effectively automates the synthesis, and more importantly, permits the use of a continuous flow microwave reactor for commercial preparation of the high quality colloidal nanoparticles.

摘要:The present disclosure relates to a seed-growth based method for the synthesis of metal nanoparticles of controlled shape (cubes, cuboids, octahedrons) and size in an aqueous environment, without the use of shape directing agents. The method involves a first step of preparing a solution comprising water, metal seed growth nanoparticles, a metal salt comprising the same metal as the metal seed growth nanoparticles, and a reducing agent; and a second step of heating the solution to between 9 and 130° C. at a rate of between 1° C./min and 5° C./min and at a pressure of between 1 and 5 atm. The method may also be carried out in a reduced oxygen atmosphere and the concentration of oxygen disclosed in the solution may be less than the concentration of oxygen in an oxygen saturated solution.

摘要:Selective gas-reducing methods for making shape-defined metal-based nanoparticles. By avoiding the use of solid or liquid reducing reagents, the gas reducing reagent can be used to make shape well-defined metal- and metal alloy-based nanoparticles without producing contaminates in solution. Therefore, the post-synthesis process including surface treatment become simple or unnecessary. Weak capping reagents can be used for preventing nanoparticles from aggregation, which makes the further removing the capping reagents easier. The selective gas-reducing technique represents a new concept for shape control of nanoparticles, which is based on the concepts of tuning the reducing rate of the different facets. This technique can be used to produce morphology-controlled nanoparticles from nanometer- to submicron- to micron-sized scale. The Pt-based nanoparticles show improved catalytic properties (e.g., activity and durability).
