Photovoltaic (PV) power forecasting is challenged by its inherent variability. Pure data-driven models struggle with generalization under data scarcity and

Single-atom catalysts exhibit exceptional catalytic efficiency and stability for water treatment. However, the catalyst recovery during continuous-flow treatment process and low mass transfer efficiency restricts its wildly application. Under this circumstance, this study developed a confined catalytic ceramic membrane through in-situ anchoring of Co-N4 single atoms onto the inner walls of ceramic membrane pores, enabling efficient peroxymonosulfate activation for tetracycline degradation. Results shows that the CoSA@CM/PMS system delivers >99% TC removal with an apparent rate constant of 0.33 min-1. Remarkably, at an ultra-short hydraulic retention time of merely 2 s, TC removal reaches approximately 75%. Subsequently, the Damköhler number analysis (Da = 0.011–0.055) demonstrates that nanoconfinement reduces diffusion distances to the nanometer scale and locally concentrates reactants, yielding apparent kinetics that far exceed bulk-phase predictions. Moreover, quenching experiments and ESR test confirm the 1O2-dominated non-radical pathway with synergistic contributions from ·OH, SO4-·, and O2-·. The membrane retains >92% TC removal over five consecutive cycles and six hours of continuous operation, with cobalt leaching below 0.01 mg/L and a stable permeate flux. Finally, The QSAR toxicity prediction verified that the catalytic system could effectively eliminate the bioaccumulation potential, developmental toxicity and mutagenicity of TC, realizing the safe and harmless transformation of pollutants. This work resolves key limitations of powder catalysts and establishes a viable platform for efficient, robust, and scalable wastewater treatment process with catalytic ceramic membrane filtration under high efficiency confined reaction.
