与传统负载型钴催化剂不同，本文提出了一种可在单位质量基础上最大化钴活性位点的多级中空氢硅酸钴纳米球(CSH-80)的溶解再生策略。由于独特的设计和精心的纳米结构，钴活性中心可以均匀地分散到结构催化剂中，实现钴中心最大限度的暴露在反应中。在活化过氧单硫酸盐(PMS)降解有机污染物过程中，CSH-80表现出优异的催化性能、良好的物理化学稳定性和长期耐用性，比传统负载型钴催化剂的效率提高1.9 ~ 3.1倍。CSH-80在有机氧化中的周转频率比传统负载型钴催化剂高出2.0 ~ 3.2倍。系统地考察了反应参数对污染物降解的影响。通过淬火试验、电子顺磁共振和光致发光等研究进一步阐明了催化氧化的机理。本研究的设计理念将为今后发展高性能钴基多相催化剂在环境修复中的应用提供新的机遇。\n

Unlike traditional supported cobalt catalysts, this paper proposes a dissolution regeneration strategy for multi-stage hollow cobalt hydrosilicate nanospheres (CSH-80) that can maximize cobalt active sites on a unit mass basis. Due to its unique design and carefully crafted nanostructure, cobalt active centers can be uniformly dispersed into the structural catalyst, achieving maximum exposure of cobalt centers in the reaction. In the process of activating peroxymonosulfate (PMS) to degrade organic pollutants, CSH-80 exhibits excellent catalytic performance, good physical and chemical stability, and long-term durability, with an efficiency increase of 1.9 to 3.1 times compared to traditional supported cobalt catalysts. The turnover frequency of CSH-80 in organic oxidation is 2.0 to 3.2 times higher than that of traditional supported cobalt catalysts. Systematically investigated the influence of reaction parameters on pollutant degradation. The mechanism of catalytic oxidation was further elucidated through quenching experiments, electron paramagnetic resonance, and photoluminescence studies. The design concept of this study will provide new opportunities for the future development of high-performance cobalt based multiphase catalysts in environmental remediation.\n
