The direct discharge of raw bathroom greywater has increased the concentrations of various pollutants in the water bodies. Typically, greywater contains large quantities of xenobiotic organic compounds (XOCs) owing to an increase in consumption of personal care and bath products. Therefore, it urges for a suitable technology to eliminate these compounds from contaminated waters. Photocatalytic degradation using Zinc Oxide nanoparticles (ZnO NPs) has the potentiality to eliminate various XOCs. However, ZnO NPs have high tendency to aggregate, which may lower the photocatalytic degradation rate. Therefore, there is an urgency to modify ZnO NPs to overcome the limitation. The present review was conducted to determine a suitable method for the modification ZnO NPs. Besides, the potential of the modified ZnO NPs in degrading XOCs in greywater as a photocatalyst was also discussed.

氧化锌纳米粒子对中水中异源生物有机化合物的光催化作用

浴室灰水的直接排放增加了水体中各种污染物的浓度。通常，由于个人护理和洗浴产品的消耗增加，灰水含有大量的异种生物有机化合物（XOC）。因此，它呼吁采用合适的技术从受污染的水中消除这些化合物。使用氧化锌纳米颗粒（ZnO NPs）进行光催化降解具有消除各种XOC的潜力。然而，ZnO NPs具有高聚集趋势，这可能降低光催化降解速率。因此，迫切需要修饰ZnO NP以克服该限制。进行本综述以确定用于修饰ZnO NP的合适方法。除了，
