1. A method of producing an organoselenium-based nanocomposite, comprising:
acid treating a mixture comprising 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; and
reacting the chlorinated TiO2-MWCNT/Biochar with an organoselenium compound and an aliphatic amine to form a Se—TiO2-MWCNT/Biochar;
wherein the organoselenium compound is selected from the group consisting of
