Fenton reagent improved cyanation and usage thereof

摘要

This disclosure provides a facial green method for metal cyanides preparation, including the following steps: 1) supported metal nanoparticles and Fenton's reagent are mixed with nitrile and then stirred to obtain suspension, wherein metal nanoparticles are selected from a nano metal, nano metal oxide and nano metal salt; 2) centrifuging the suspension to obtain a product and drying the product after stirring to obtain the metal cyanides. As prepared metal cyanides have broad application prospects in the fields of sensor, battery, medicine, electroplating and catalysis. This Fenton-improved cyanation (FIC) method may effectively exclude the toxicity from free cyanide anions and get rid of UV-light, being more energy-saving and more feasible for large-scale industrial production of MCs.

主权项

1. A method of preparation of metal cyanides, the method comprising:
1) mixing supported metal nanoparticles, Fenton's reagent, and nitrile to obtain suspension and stirring the suspension, the supported metal nanoparticles comprising carriers loading one or more compositions comprising at least one of a nano metal, a nano metal oxide and a nano metal salt; 2) centrifuging the suspension to obtain a product and drying the product to obtain the metal cyanides.
