  • Method of producing organoselenium-based nanocomposite
    Patent number: 12115524
    Abstract: A method of producing an organoselenium-based nanocomposite includes acid-treating a mixture containing multi-walled carbon nanotubes (MWCNT) and palm waste with phosphoric acid to form an acid-treated mixture; carbonizing the acid-treated mixture to form a MWCNT/biochar; mixing the MWCNT-biochar with TiO2 nanoparticles to form a TiO2-MWCNT/biochar; chlorinating acyl groups present on the TiO2-MWCNT/biochar to form a chlorinated TiO2-MWCNT/biochar; reacting the chlorinated TiO2-MWCNT/biochar with an organoselenium compound to form a Se—TiO2-MWCNT/biochar.
