Abstract
Official abstract text for this publication.
The invention provides a method of converting nitrogen into ammonia. The method comprises contacting an electrocatalyst with an aqueous solution of dissolved nitrogen gas. The electrocatalyst comprises carbon nanospikes doped with nitrogen.
First claim
Opening claim text (preview).
What is claimed is: 1. A method of converting nitrogen into ammonia, the method comprising contacting an electrocatalyst with an aqueous solution of dissolved nitrogen gas, said electrocatalyst is electrically powered as a cathode and is in electrical communication with a counter electrode electrically powered as an anode, wherein a voltage across said cathode and said anode is within a range of 2 to 4 volts, to convert said dissolved nitrogen gas into ammonia; wherein said electrocatalyst comprises carbon nanospikes doped with nitrogen. 2. The method of claim 1 , wherein said electrocatalyst is housed in a first compartment of an electrochemical cell, wherein said first compartment contains said aqueous solution in contact with said electrocatalyst; said counter electrode is housed in a second compartment of said electrochemical cell, wherein said second compartment also contains said aqueous solution. 3. The method of claim 1 , wherein said carbon nanospikes contain layers of puckered carbon. 4. The method of claim 1 , wherein at least a portion of the carbon nanospikes contain a straight or curled tip. 5. The method of claim 4 , wherein said straight or curled tip has a width ranging from 0.5 nm to 3 nm. 6. The method of claim 1 , wherein said carbon nanospikes have a length ranging from 20 nm to 100 nm.
