An electrocatalyst comprising (i) carbon nanospikes and (ii) copper alloy nanoparticles containing copper and at least one noble metal and residing on and/or between the carbon nanospikes. Also disclosed herein is a method of producing the electrocatalyst. Also described herein is a method for converting carbon dioxide into hydrocarbons by use of the above-described electrocatalyst. The method for producing hydrocarbons more specifically involves contacting the electrocatalyst with an aqueous solution of a bicarbonate salt while the aqueous solution is in contact with a source of carbon dioxide, and electrically powering the electrocatalyst as a cathode at negative potential condition while the cathode is in electrical communication with a counter electrode electrically powered as an anode, to convert the carbon dioxide into hydrocarbons containing at least four carbon atoms and composed of only carbon and hydrogen.

Alloy based electrochemical catalyst for conversion of carbon dioxide to hydrocarbons

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.

Electrochemical catalyst for conversion of nitrogen gas to ammonia

The invention is directed to a method for producing metal-containing (e.g., non-oxide, oxide, or elemental) nano-objects, which may be nanoparticles or nanowires, the method comprising contacting an aqueous solution comprising a metal salt and water with an electrically powered electrode to form said metal-containing nano-objects dislodged from the electrode, wherein said electrode possesses a nanotextured surface that functions to confine the particle growth process to form said metal-containing nano-objects. The invention is also directed to the resulting metal-containing compositions as well as devices in which they are incorporated.
