  • Method of fabricating macroporous carbon capsules from pollen grains
    Patent number: 9346678
    Abstract: A method of producing macroporous carbon capsules includes providing pollen grains from date palm (Phoenix dactylifera L.) males, drying the pollen grains, heating the dried pollen grains to a temperature of at least 500° C. under an atmosphere of N2 gas to produce macroporous carbon capsules. The macroporous carbon capsules produced from the above method can have an oval shape with a diameter in the range of about 18 ?m to about 20 ?m. The macroporous carbon capsules have a mean pore diameter in the range of about 50 nm to about 450 nm. The pores are three-dimensionally interconnected via nanoscopic carbon walls. The carbon walls have a thickness of about 4 ?m.
