MICROWAVE-ASSISTED SYNTHESIS OF CARBON AND CARBON-METAL COMPOSITES FROM LIGNIN, TANNIN AND ASPHALT DERIVATIVES AND APPLICATIONS OF SAME

摘要

A plurality of carbon-metal nanocomposites. In one embodiment, the plurality of carbon-metal nanocomposites includes a plurality of carbons with a molecular structure that shows a first peak in the range of 1585 to 1565 cm⁻¹ in a corresponding Raman spectrum, and a second peak in the range of 1325 to 1355 cm⁻¹ in the corresponding Raman spectrum, wherein the first peak represents carbons with a graphitic nature and the second peak represents nanodiamonds, and wherein the plurality of carbon-metal nanocomposites is made from a metal derivative or metal chelated derivative of a carbon-containing precursor in solid form that is subjected to microwave radiation at a frequency in the range of 900 MHz to 5.8 GHz, for a period of time effective to allow the plurality of carbon-metal nanocomposites to be formed.
