In this paper, a novel heterostructure of 0D/3D-CdSe/Bi[Formula: see text]TiO[Formula: see text] pyramidal photocatalyst was synthesized and characterized. It exhibited significantly photocatalytic efficiency in photocatalytic degradation of the tetracycline than pure Bi[Formula: see text]TiO2 and CdSe and showed high stability. The enhanced photocatalytic activity might be attributed to the formation of heterostructure between CdSe QDs and 3D Bi[Formula: see text]TiO[Formula: see text], in which CdSe QDs served as electron trapper to improve the separation of photodegradation electron–hole pairs, and provided a number of active adsorption sites for the photogenerated of pollutants. The photocatalytic mechanism of 0D/3D-CdSe/Bi[Formula: see text]TiO[Formula: see text] pyramidal heterostructure was also proposed.
