Metal–organic frameworks (MOFs) derived metal oxides/carbon catalysts have attracted a lot of attention in the field of environmental remediation, but the agglomeration of MOFs derived metal oxides remains a challenge. Herein, low-cost and readily accessible pomelo peel (PP) was chosen as a high-quality carrier for MOFs (ZIF-67). In situ growth of ZIF-67 on PP cores was followed by one-step pyrolysis of the PP/ZIF-67 material to yield the derivative composite material (Co₃O₄/C-PC). The degradation of CIP in water by Co₃O₄/C-PC activated peroxymonosulfate (PMS) was investigated. The results reveal that the CIP degradation efficiency in the Co₃O₄/C-PC/PMS system can reach 93.3 %, and the system has good durability and anti-interference ability, and can be applied to a wide pH range of 5–11. The effects of various experimental parameters were investigated. The radical pathway (SO₄⁻ and OH) and the nonradical pathway (¹O₂) both contributed to the degradation of CIP. This work proposes new ideas for the preparation of low-cost biomass/MOFs derived catalysts for the application of water treatment.

金属有机框架（MOFs）衍生的金属氧化物/碳催化剂在环境修复领域引起了广泛的关注，但MOFs衍生的金属氧化物的团聚仍然是一个挑战。在此，低成本且易于获取的柚子皮 (PP) 被选为 MOF (ZIF-67) 的高质量载体。ZIF-67 在 PP 芯上的原位生长，随后 PP/ZIF-67 材料的一步热解产生衍生复合材料 (Co ₃ O ₄ /C-PC)。_{研究了Co 3} O ₄ /C-PC活化过一硫酸盐(PMS)对水中CIP的降解作用。结果表明，CIP 降解效率在 Co ₃ O ₄/C-PC/PMS体系可达93.3%，体系具有良好的耐久性和抗干扰能力，可适用于5-11的宽pH范围。研究了各种实验参数的影响。自由基途径（SO ₄ ^-和OH）和非自由基途径（¹ O ₂）均有助于 CIP 的降解。这项工作为制备用于水处理应用的低成本生物质/MOFs衍生催化剂提出了新思路。
