Hierarchical porous nanosheet-assembled MgO microrods with high adsorption capacity

• Hierarchical porous nanosheet-assembled MgO microrods (PS-MgO) were synthesized.
• PS-MgO has a porous nanosheet structure with a specific surface area of 72 m2/g.
• The high adsorption capacity of PS-MgO means it shows potential in water treatment.

Hierarchical porous nanosheet-assembled MgO microrods (PS-MgO) are synthesized by a simple surfactant-assisted method. Because of its unique porous nanosheet-assembled structure, the specific surface area of PS-MgO reaches 72 m2/g. Congo red adsorption experiments indicate that PS-MgO shows an adsorption capacity that is three times higher than that of MgO microrods.

Hierarchical porous nanosheet-assembled MgO microrods with a specific surface area of 72 m2/g are synthesized. Their adsorption capacity is three times than that of MgO microrods, suggesting potential for application in water treatment.Figure optionsDownload as PowerPoint slide
