Biochar has been widely employed for the promotion of advanced oxidation processes (AOPs) and when combined with nitrogen doping for charge distribution mediation, N-doped biochar (NBC) can serve as a highly effective catalyst for the degradation of persistent organic pollutants. However, due to the variety of doping and preparation methods, the intrinsic active sites for AOP catalysis have not been clearly identified. Furthermore, the complex relationships between preparation method, material properties, and catalytic degradation pathways remain unclear, impeding the widespread practical application of NBC. Herein, machine learning (ML) was implemented to predict the degradation pathway and identify the vital properties of N-doping required for the acceleration of AOPs. During the process of model training, an innovative method of data set splitting was applied, comparing the results generated from multiple models to enhance model interpretability. We elucidated the correlation between the primary features and nonradical pathway, focusing on the contribution of N species and the regulatory role of pyrolysis temperature. Detailed insights were further provided to enhance the ratio design of NBC for nonradical mediation. Overall, this study offers novel insights into NBC-mediated AOPs for pollution control, underscoring the significant potential of ML for accelerating catalyst applications.

“…The oxidation-reduction potential, environmental friendliness, and selectivity for removing refractory organic pollutants attributed to the redox properties of PS make it possible for a viable alternative to replace H 2 O 2 [10,11]. However, the oxidation property of PS itself is not prominent, and the performance could be strengthened by means of activation [12]. SO 4 • − could be generated efficiently by activating peroxide bonds in PS using external energy (heat, ultrasound, UV irradiation, or microwave), metallic materials (mostly transition metals), and non-metallic materials (carbon-based material materials, quinones, or strong alkaline) [13].…”

BiOCl/graphene aerogel graphene (BGA) was successfully obtained by in situ hydrothermal synthesis, and the chemical, structural, morphological, and photocatalytic properties were systematically characterized. BGA with the doping amount of BiOCl at 20% (BGA-4) exhibited the optimal activation efficiency for persulfate (PDS) on the degradation of methyl orange (MO) under simulated sunlight (SSL) illumination as compared to the pure graphene (GA) and aerogel composites with different BiOCl content. The influence of various reaction parameters on the MO removal efficiency, such as the reaction system, catalyst activator dose, PDS concentration, BiOCl doping amount, and the initial pH of the solution, was investigated. Under optimum conditions, the catalytic efficiency of BiOCl-doped GA with the mass ratio of 20% (BGA-4) was 5.61 times that of GA. The strengthening effect of BGA-4 benefited from the synergistic effect of 1O2, O2·− and the generation and rapid electron transfer of photo-induced electron (e−) in the BGA-4/SSL/PDS system. Considering the superior stability and recyclability of BGA-4, the BGA-4/SSL/PDS system exhibits great potential in actual wastewater treatment.
