NOVELTY - Synthesizing at least one carbon nanomaterial, by: selecting raw material; ball milling, dried pieces of the material; sonicating, the powdered form of the material to form resultant powder; transferring, after the sonicating, the resultant powder to reactor after dispersing the material in powdered form into preselected quantity of distilled water (DI), performing, over the resultant powder, hydrothermal process in vacuum furnace in the reactor to form liquid; washing the liquid, with the DI water and ethanol followed by filtering with a filter paper to form resultant liquid; and washing, the resultant liquid with dichloromethane (DCM), followed by exposure of the resultant liquid in UV light, where the DCM results in leftover solid mass of the resultant liquid, and the exposure of the resultant liquid allows synthesis of at least one resultant carbon nano particle and the leftover resultant solid mass is also processed to form the resultant carbon nanomaterials. USE - The method is useful for synthesizing at least one carbon nanomaterial. ADVANTAGE - The method: provides bulk production with improved quality; and is cost-effective, consume less time and high efficiency. DETAILED DESCRIPTION - Synthesizing at least one carbon nanomaterial, by: selecting, a raw material, where the raw material is pre-processed and is selected in a predefined size; ball milling, dried pieces of the raw material for a predefined time, for obtaining the raw material in a powdered form; sonicating, the powdered form of the raw material for a predefined time for obtaining a resultant powder; transferring, after the sonicating, the resultant powder to a reactor after dispersing the raw material in powdered form into a preselected quantity of distilled water (DI), performing, over the resultant powder, a hydrothermal process for a predefined time in a vacuum furnace in the reactor, at a predefined temperature, for obtaining a liquid; washing the liquid, with the DI water and ethanol followed by filtering with a filter paper for obtaining a resultant liquid; and washing, the resultant liquid with dichloromethane (DCM), followed by exposure of the resultant liquid in UV light, where the DCM results in leftover solid mass of the resultant liquid, and the exposure of the resultant liquid allows synthesis of at least one resultant carbon nano particle and the leftover resultant solid mass is also processed for obtaining the resultant carbon nanomaterials.
