Hormuz Red Soil (HRS), as a naturally hematite-containing mineral was used to enhance the catalytic ozonation process (COP) of Acetaminophen (ACT) elimination. The surface properties and particle size of HRS mainly composed of ɑ-Fe₂O₃ were modified via calcination (C-HRS) demonstrating notable catalytic activity. The catalytic activity of C-HRS was evaluated for the ozonation of ACT under various conditions. Complete degradation of 50 mg L⁻¹ ACT was obtained within 10 min at natural conditions with 1.0 g L⁻¹ of C-HRS which was > 10 times faster than single ozonation process (SOP). The C-HRS accelerated the decomposition of ozone to hydroxyl radical on the catalyst’s surface. Moreover, the C-HRS efficiently catalyzed the peroxone reaction for the degradation and mineralization of ACT. The C-HRS exhibited high stability and reusability in consecutive catalytic cycles. This work offers a new, effective, and low-cost catalyst for accelerating of ozone decomposition that can be used in oxidation of pollutants.

霍尔木兹红土 (HRS)，作为一种天然含赤铁矿的矿物，用于增强对乙酰氨基酚 (ACT) 消除的催化臭氧化过程 (COP)。主要由ɑ -Fe ₂ O ₃组成的 HRS 的表面性质和粒径通过煅烧 (C-HRS) 进行改性，显示出显着的催化活性。在各种条件下评估了 C-HRS 对 ACT 臭氧化的催化活性。在自然条件下，1.0 g L ^-1 50 mg L ^-1 ACT 在 10 分钟内完全降解C-HRS 比单一臭氧化过程 (SOP) 快 10 倍以上。C-HRS 加速了臭氧分解为催化剂表面的羟基自由基。此外，C-HRS 有效地催化过氧酮反应以降解和矿化 ACT。C-HRS 在连续催化循环中表现出高稳定性和可重复使用性。这项工作为加速臭氧分解提供了一种新的、有效的、低成本的催化剂，可用于污染物的氧化。
