Abstract
A method of producing a Se/Biochar-Au—Bi2O3/TiO2 catalyst includes acid treatment of a palm waste with phosphoric acid to form an acid-treated palm waste, carbonizing the acid-treated palm waste to form an acid-treated biochar, and chlorinating acyl groups present on the acid-treated biochar with oxalyl chloride to form a chlorinated biochar. The method may include reacting the chlorinated biochar with an organoselenium compound to form an organoselenium-functionalized biochar and mixing the organoselenium-functionalized biochar with Au-doped Bi2O3/TiO2 particles to form the Se/Biochar-Au—Bi2O3/TiO2 catalyst.
