An apparatus and a method for producing carbon, oxygen and optionally nitrogen from treated flue gases are provided. The apparatus provides a thermo-dielectric-electric field that splits molecules of carbon dioxide and carbon monoxide into carbon and oxygen and nitrogen oxides into nitrogen and oxygen. The carbon is recovered in a variety of solid forms, and oxygen and nitrogen are recovered as gases.

A controllable preparation method for a plasmonic nanonail structure is provided. A size of a nanomaterial can be controlled at sub-wavelength. The nanomaterial has good localized surface plasmon resonance effect, and the optical, electrical and mechanical properties of the nanometer material all can be regulated. The plasmonic nanonail is composed of two parts, i.e., a silver nanorod, a gold nanorod or a silver-gold-silver alloy nanorod and an approximate equilateral triangular nano-silver plate growing on the nanorod. A length of the nanorod is controlled within 20-30 nanometers, a diameter of the nanorod is controlled within 10-200 nanometers, a side length of the triangular nano-silver plate is controlled within 20 nanometers to 2 microns, and a size of the triangular plate is less than or equal to the length of the nanorod.
