Abstract

Heterogeneous persulfate activation is promising for water treatment due to its low energy consumption, easy catalyst recovery, and wide pH applicability. However, the performance of conventional metal‑based catalysts requires further improvement. Here, the high‑entropy alloy sulfide (MoFeMnNiCo)S_1.33 was synthesized via ball milling and evaluated as a persulfate activator. The as-prepared catalyst was systematically characterized by methods such as X-ray diffraction (XRD), scanning electron microscopy (SEM), transmission electron microscopy (TEM), and X-ray photoelectron spectroscopy (XPS). The effectiveness of (MoFeMnNiCo)S_1.33 activated persulfate in degrading organic pollutants was investigated, and the influence of various factors on the catalytic activity of the system was explored. Under the activation of persulfate by (MoFeMnNiCo)S_1.33, the degradation rate constant of AP is 0.2566 min⁻¹ (catalyst dosage = 0.2 g/L, PMS dosage = 0.3 g/L, AP = 20 mg/L, 25 ℃), which is 6.24 times that of CoS₂.

高熵硫化合金降解对乙酰氨基酚的高效活化剂

非均相过硫酸盐活化法具有能耗低、催化剂回收容易、pH适用范围广等优点，在水处理中具有广阔的应用前景。然而，传统金属基催化剂的性能需要进一步改进。本文采用球磨法合成了高熵硫化合金（MoFeMnNiCo）S1.33，并对其作为过硫酸盐活化剂进行了评价。采用x射线衍射（XRD）、扫描电子显微镜（SEM）、透射电子显微镜（TEM）、x射线光电子能谱（XPS）等方法对催化剂进行了系统表征。考察了（MoFeMnNiCo）S1.33活化过硫酸盐降解有机污染物的效果，并探讨了各因素对该体系催化活性的影响。在（MoFeMnNiCo）S1.33过硫酸盐活化下，AP的降解速率常数为0.2566 min−1（催化剂用量为0.2 g/L， PMS用量为0.3 g/L, AP = 20 mg/L, 25℃），是CoS2的6.24倍。

期刊介绍： Water, Air, & Soil Pollution is an international, interdisciplinary journal on all aspects of pollution and solutions to pollution in the biosphere. This includes chemical, physical and biological processes affecting flora, fauna, water, air and soil in relation to environmental pollution. Because of its scope, the subject areas are diverse and include all aspects of pollution sources, transport, deposition, accumulation, acid precipitation, atmospheric pollution, metals, aquatic pollution including marine pollution and ground water, waste water, pesticides, soil pollution, sewage, sediment pollution, forestry pollution, effects of pollutants on humans, vegetation, fish, aquatic species, micro-organisms, and animals, environmental and molecular toxicology applied to pollution research, biosensors, global and climate change, ecological implications of pollution and pollution models. Water, Air, & Soil Pollution also publishes manuscripts on novel methods used in the study of environmental pollutants, environmental toxicology, environmental biology, novel environmental engineering related to pollution, biodiversity as influenced by pollution, novel environmental biotechnology as applied to pollution (e.g. bioremediation), environmental modelling and biorestoration of polluted environments. Articles should not be submitted that are of local interest only and do not advance international knowledge in environmental pollution and solutions to pollution. Articles that simply replicate known knowledge or techniques while researching a local pollution problem will normally be rejected without review. Submitted articles must have up-to-date references, employ the correct experimental replication and statistical analysis, where needed and contain a significant contribution to new knowledge. The publishing and editorial team sincerely appreciate your cooperation. Water, Air, & Soil Pollution publishes research papers; review articles; mini-reviews; and book reviews.
