05/05/2019 During the ball milling procedure, solid raw materials are caught between dynamic impacting balls, such that sizes of particles are decreased, shapes are changed, chemical bonding is broken and new surfaces are gradually produced at room temperature by kinetic energies of the balls [25,26]. In comparison with solvothermal synthesis, ball milling is potentially a scalable, energy

Efficient removal of volatile organic compound by ball

Increasing the surface area by ball milling is conducive to the diffusion of hydrophobic VOCs molecules such as toluene to the adsorption sites in the biochar. However, for hydrophilic VOCs such as acetone, higher oxygen functional groups were the main reason for the enhanced adsorption by ball milling. Therefore, ball-milled biochar can be used as a potential adsorbent material in VOCs treatment.
