As depicted in Figure 7a, an increase in catalyst dosage from 0.005 g to 0.015 g resulted in a significant improvement in degradation efficiency (83% within 40 min).…”

“…The key factor in photocatalysis technology lies in the choice of photocatalyst. Currently, commonly used semiconductor photocatalysts for degrading organic pollutants include TiO 2 [6][7][8], CdS [9][10][11][12], ZnO [13][14][15][16], and Bi 2 O 3 [17][18][19][20], among others. However, the electrons and holes in this kind of photocatalyst are easy to recombine, resulting in low photocatalytic performance.…”
