Zerovalent iron (ZVI) catalysts have recently been evaluated for wastewater remediation applications because of their highly efficient catalytic properties and its low cost, which results from its natural abundance and easy production; although passivation, agglomeration, and corrosion may significantly reduce their activity, limiting their photocatalytic efficiency. ZVI has been combined or doped with different materials to overcome these drawbacks. This review thoroughly presents and integratedly analyzes the most recent and innovative results of ZVI-combining photocatalysts applied to the treatment of contaminants of emerging concern. These newly doped or combined catalysts have addressed a high activity and hold a great potential of application in photocatalysis in the closest future. Further research on ZVI catalysts must be focused on the assessment of its performance applied to the treatment of a wider range of target polluting substances and the scaling up of high-efficient processes to a feasible industrial level.

零价铁（ZVI）催化剂由于其天然的丰度和易于生产而具有高效的催化性能和低成本，因此最近已被评估用于废水修复。尽管钝化，结块和腐蚀可能会大大降低它们的活性，从而限制了它们的光催化效率。ZVI已被组合或掺杂了不同的材料，以克服这些缺点。这篇综述全面介绍并综合分析了用于处理新出现的污染物的ZVI组合光催化剂的最新成果和创新成果。这些新掺杂或组合的催化剂已经解决了高活性，并且在不久的将来具有在光催化中的巨大应用潜力。
