Hollow macroporous CeO2/β-Bi2O3 heterostructure sphere via one-step spray solution combustion synthesis for efficient photocatalysis

Construction of a novel S-type γ-Bi2O3/CeO2 heterojunction for highly efficient photocatalytic degradation of antibiotics

“…32 The CeO 2 /β-Bi 2 O 3 could remove the dyes, antibiotics, and NO, while the improvement quantities were lower than 20%. 33–37 In the above studies, the α-Bi 2 O 3 and β-Bi 2 O 3 constituted a II-type and a direct Z-type heterojunction with CeO 2 to enhance the photocatalytic performance. For the II-type heterojunction, the electrons transfer on the conduction band (CB) of the two semiconductors and the holes migrate on their valence band (VB).…”
