摘要：

The binary TiO2-ZrO2 particles were better alternative to TiO2 particles as photocatalyst to reduce humic acid fouling in photocatalytic membrane reactor. The structure of the TiO2-ZrO2 particles was strongly dependent upon the content of zirconium as an additive. A composition of 50% TiO2 with 50% ZrO2 was optimal in terms of physicochemical properties. The effect of TiO2-ZrO2 particles on the reduction of humic acid fouling was further improved by the presence of divalent cations such as calcium. Nevertheless, the stability of polymeric membranes in longer-term operation using a hybrid photocatalytic membrane reactor for water treatment applications may remain a challenge.
