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.

A method of treating a palm waste to form 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, wherein the chlorinating includes refluxing the TiO2-MWCNT/Biochar with an excess of oxalyl chloride in an ultrasonic bath;
- 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
