A facile approach to fabricate porous UMCM-150 nanostructures and their adsorption behavior for methylene blue from aqueous solution

Abstract

Well-dispersed hierarchical flower-like and net-like architectures of UMCM-150 were successfully prepared by a facile and rapid method at room temperature. Owing to the high surface area and pore volume, the UMCM-150 flower-like nanostructures exhibit excellent adsorption capability for the dye of methylene blue (MB) with a maximum capacity of 560 mg g⁻¹, which is higher than that of most materials reported to date. The influence of variables such as initial pH and MB concentration, contact time and shape of UMCM-150 nanostructures was investigated. The results indicate that the UMCM-150 nanostructures have promising application in the MB dye containing wastewater treatment.
