1：Experimental Design and Method Selection:

The study involved the synthesis of oxidized black phosphorus (oBP) nanosheets coupled with reduced graphene oxide (rGO) to form a hybrid material. The methodology included controlled ozonation, vacuum filtration, and thermal treatment to achieve the desired material properties.

2：Sample Selection and Data Sources:

The samples were characterized using SEM, HR-TEM, STEM, XRD, FTIR, Raman spectroscopy, XPS, and solid-state 31P NMR spectroscopy. Electrochemical measurements were conducted to evaluate the performance of the hybrid material.

3：List of Experimental Equipment and Materials:

Equipment included a Philips SEM 535M, JEM-3010 HRTEM, Titan G2 60-300 unit, Rigaku D/max IIIC XRD, JASCO FT/IR-4700 spectrometer, Thermo MultiLab 2000 XPS system, and a BioLogic Science instrument VSP for electrochemical measurements.

4：Experimental Procedures and Operational Workflow:

The synthesis involved the exfoliation of BP into nanosheets, controlled ozonation, and hybridization with GO followed by thermal treatment to form the oBP/rGO hybrid. Electrochemical characterization was performed to assess capacitance, rate capability, and cycling stability.
