Methods of producing carbon nanoparticles

Research Field: Material/Carbon nanostructure

Content of research: 

    Typically, the palm fronds can be carbonized at around 400 C, then ball milled for several hours, then dispersing the milled powder in a liquid to form a suspension; sonicating the suspension to form the ultra-fine carbon nanoparticles; and collecting the carbon nanoparticles. Activation can be done chemically by using NaOH or physically using CO2 or steam.Six products can be produced, which are:

- Carbonized date palms powder micro size powder (simple grinding).

- Ball milled powder (Ball milling for 8-12 h to get a mixture of sub micro and nanosized particles).

- Ball milled-sonicated powder (Ball milling for 8-12 h and sonicated for 2-3 h to get Ultrafine nanoparticles).

- Activated carbon of carbonized micro size powder (Chemically activated by NaOH, or physically by CO2 or steam).

- Activated carbon of ball milled carbonized nanoparticle powder (Chemically activated by NaOH, or physically by CO2 or steam)..

- Activated ultrafine carbon nanoparticles (Chemically activated by NaOH, or physically by CO2 or steam).
