Abstract Two‐dimensional materials have gained significant attention across the community due to their remarkable physical, chemical, electronic, and optical properties. With many two‐dimensional discovered each year, investigations into processing, scalability, resulting properties are important fully realize potential in next‐generation technologies. While numerous exfoliation techniques available for a variety of materials, liquid‐phase offer advantages, particularly high throughput scalability. Herein, we report method access multilayer cobalt oxide nanosheets pH‐neutral aqueous solutions varying size, concentration, application. The thickness, morphology were confirmed using atomic force microscopy transmission electron microscopy. Finally, selected underwent additional analysis crystallinity, structure, valance.
