Developing effective and stable photocatalysts for organic pollutants degradation are still a big challenge in practical water treatment now. In this work, la doped zno–tio2composite(la/zno–tio2) were successfully fabricated by using PVP modified ZIF-8/tio2as template via the absorption and pyrolysis routes. All as-fabricated materials were analyzed by XRD, SEM, TEM, BET, XPS, UV–vis absorption spectra and ESR spectra. PVP modified ZIF-8/tio2was fully transferred into zno–tio2after being pyrolyzed at high temperature under air *** doping of la can make zno–tio2exhibiting red-shifted, which is attributed to the capture of photo-generated electrons by la, leading to the effective separation between photo-generated electrons and holes. Furthermore,the photocatalytic performance of all as-fabricated materials were explored by degradation of tetracycline(TC)solution under UV light irradiation. la/zno–tio2exhibits excellent stability. And the photocatalytic degradation rate of la/zno–tio2is 99.2%, which is even higher than zno(87.4%), zno–tio2(87.4%), P25(tio2)(92.7%).More than that, the effect of catalyst’s dose, effect of TC concentration and effect of pH for TC degradation have been well explored. The excellent photocatalytic performance of la/zno–tio2makes it possible to be applied for degradation of organic pollutants in practice.
