Abstract
A nanoparticle includes a metal-based core, a first coating layer substantially covering the metal-based core to generate a coated metal-based core, and a second coating layer at least partially covering the coated metal-based core, wherein the metal-based core comprises at least one transition metal, and wherein the metal-based core comprises the at least one transition metal substantially in a state of zero oxidation.
Claims26
A nanoparticle comprising:
- a metal-based core,
- a first coating layer substantially covering the metal-based core to generate a coated metal-based core, and
- a second coating layer at least partially covering the coated metal-based core, wherein the metal-based core comprises at least one transition metal, and wherein the metal-based core comprises the at least one transition metal substantially in a state of zero oxidation.
A method for synthesizing a nanoparticle, the method comprising the steps of:
- (i) preparing a metal oxide nanoparticle comprising a metal oxide with a chemical structure represented as MnOmH2O,
- wherein M is a transition metal, n is an integer between 1 and 5, m is an integer between 1 and 10, and b is an integer between 0 and 20,
- (ii) coating the metal oxide nanoparticle with a first coating layer substantially covering the metal oxide nanoparticle with a layer comprising a first compound to generate a coated metal oxide nanoparticle,
- (iii) reducing the coated metal oxide nanoparticle with a suitable reducing agent, wherein the reducing agent causes the metal oxide of the coated metal oxide nanoparticle to reduce to a state of zero oxidation to generate a coated metal-based core nanoparticle, and
- (iv) coating the coated metal-based core nanoparticle with a second coating layer partially covering the coated metal-based core nanoparticle with a compound comprising at least one moiety to obtain a double-coated metal-based core nanoparticle.
