The excessive uses of pharmaceuticals and personal care products (PPCPs) have led to the presence of trace amount of PPCPs in water bodies. Photocatalysis can be an efficient technology for the challenging PPCPs remediation in the environment. A nontoxic and stable compound, α-Fe₂O₃, possesses a lower band gap and magnetism and can be a potential catalyst for photocatalytic and photochemical degradation of PPCPs. However, the application of α-Fe₂O₃ in photocatalysis is limited due to the faster recombination of electron–hole pairs. In recent years, numerous studies on α-Fe₂O₃ modification to improve its photocatalytic efficiency have been published. This article provides a brief summary and progress on α-Fe₂O₃-based nanomaterials for the degradation of various PPCPs by photocatalysis and photochemical oxidation.

药物和个人护理产品（PPCP）的过度使用导致水体中存在痕量的PPCP。对于在环境中具有挑战性的PPCP修复，光催化可以是一种有效的技术。无毒的和稳定的化合物，的α-Fe ₂ ö ₃，具有低的能带隙和磁性并且可用于的PPCPs的光催化和光化学降解的电位催化剂。然而，α-Fe的应用₂ Ó ₃在光催化作用由于电子-空穴对的重组更快限制。近年来，在大量研究的α-Fe ₂ Ø ₃已经公开了改进其光催化效率的修饰。本文提供了一个简要概述，并且进展上的α-Fe ₂ ö ₃用于通过光催化和光化学氧化各种的PPCPs的降解基于纳米材料。
