| titleOfInvention | Metal selenide coats the two-step method synthetic method of noble metal nanocrystalline |
| abstract | The invention discloses a kind of metal selenide cladding noble metal nanocrystalline and its two-step method synthetic methods.In some embodiments, metal selenide cladding noble metal nanocrystalline includes the metal selenide shell of the noble metal nano particles and the cladding noble metal nano particles as kernel.In some embodiments, which includes：After selenium source is added into the aqueous dispersion of noble metal nano particles, reducing agent is added at 25~45 DEG C again and is stirred to react 10~20min, the reaction system for coating noble metal nano particles intermediate containing selenium is made, source metal is added later and reacts 3~10h, obtains target product.The present invention provides the methods that a kind of two-step method synthesis metal selenide coats noble metal nanocrystalline, its mild condition, preparation process is simple, it is simple to operation, condition is easy to control, and product morphology is controllable, it may be implemented using noble metal nano particles as kernel, large-scale production of the different metal selenides as the composite nano materials of shell. |
