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.

Abstract: The present invention belongs to the field of new material technology and relates to a bismuth/bismuth titanate heterojunction hollow nanospheres and methods for preparing the same and applications thereof. The bismuth/bismuth titanate heterojunction hollow nanospheres is obtained by adding a bismuth salt and tetrabutyl titanate into an organic solvent, mixing evenly, adding an inorganic alkali solution to generate a precipitation, then sequentially adding an organic amine and an organic acid, performing a solvothermal treatment to obtain bismuth titanate hollow nanospheres, and then thermally reducing the bismuth titanate hollow nanospheres with a borohydride under an inert atmosphere. The bismuth/bismuth titanate heterojunction hollow nanospheres provided not only exhibit significant photocatalytic activity in degrading tetracycline hydrochloride but also enable a tighter binding of the metal to the photocatalytic material, thus offering superior structural stability.
