Abstract
Described herein is the controlled room temperature acousticmicrofluidic-based one-step template-free fabrication of porous multimetallic nanocrystals containing one or more 3d transition metals with tunable size, shape, and composition.
Claims20
A method for the synthesis of porous multimetallic nanocrystals comprising at least one 3d transition metal wherein the method comprises the following steps:
- a) mixing the at least one 3d transition metal precursor and the at least one metal catalyst precursor in an aqueous solution of a non-ionic copolymer or surfactant and optionally adding a reducing agent to form a mixture;
- b) continuously irradiating the mixture with acoustic waves at room temperature for no more than about 30 seconds to afford the porous multimetallic nanocrystals;
- and
- c) isolating and purifying the porous multimetallic nanocrystals.
