AI Technical Summary
Traditional heterogeneous catalysts suffer from problems such as low atom utilization, insufficient exposure of active sites, and easy precipitation of metal ions when treating recalcitrant organic pollutants, resulting in low catalytic efficiency and easy secondary pollution. High-temperature pyrolysis preparation methods are also prone to metal atom aggregation and support structure collapse.
A non-high-temperature pyrolysis metal single-atom catalyst was prepared under low-temperature conditions using a solvothermal method. Amide solvents were used as dispersants, reducing agents, and nitrogen sources, combined with graphene oxide and transition metal compounds to form a three-dimensional porous non-high-temperature pyrolysis metal single-atom catalyst, thus avoiding metal atom aggregation and support structure collapse caused by high-temperature pyrolysis.
This catalyst achieves high atom utilization and good stability, exhibits high efficiency in catalyzing the degradation of organic pollutants by persulfate, and avoids high energy consumption and secondary pollution. It also features a three-dimensional porous structure that provides abundant mass transfer channels and high catalytic activity.
