Sub-nanometer catalysts have drawn great attention based on their superior catalytic activity and extensive application in advanced oxidation processes(AOPs). Nonetheless, the precise regulation of the coordination environment and exploration of the peroxymonosulfate(PMS) activation mechanism remain the focus of ***, we report the preparation of Fe catalysts with diverse sizes, including single atoms(SAs), double atoms(DAs), and nanoparticles(NPs) via adjusting the precursor. Sub-nanometric Fe catalysts exhibit a higher catalytic activity for Bisphenol A(BPA) degradation. It is confirmed that the catalytic activity of the Fe diatomic catalysts(Fe2–N/C) is 2.5 times that of the Fe single-atom catalysts(Fe1–N/C) and 8.3 times that of the Fe-nanoparticleloaded catalysts(FeNP–N/C). Broad pH adaptation ranges and reusability have also been proved. Based on experimental verification and density functional theory, non-free radical pathways dominate the degradation process of BPA, while free radical pathways are in an auxiliary position, accompanied by electron transfer *** is found that the synergistic effect of Fe2–N6sites and pyridinic N adsorption centers contribute to the ultra-high catalytic activity of Fe2–N/C. This work opens up an efficient way for single atom catalysts-based advanced oxidation processes for the efficient removal of refractory organic pollutants.

With the development of medical sensors and IoT, personalized service assisted elder and patient living is a critical service in IoT-based healthcare application. However, the scale and complexity of personalized service is increasing because of ubiquitous deployment of various kinds of medical sensors, which cause response time increase and resource waste. Therefore, leveraging the advantage of complex event processing(CEP) in data stream processing, we propose a hierarchical fog-cloud computing CEP architecture for personalized service to accelerate response time and reduce resource waste. Firstly, we introduce the proposed architecture, which includes sensor layer, fog layer and cloud layer. Secondly, we propose a series of optimizations for the architecture, there are a partitioning and clustering approach and a communication and parallel processing policy to optimize the fog and cloud computing. Finally, we implement a prototype system based on the architecture named Fog Cep Care. experimental result shows that Fog Cep Care is superior to the traditional IoT-based healthcare application.
