Sol-gel synthesis and adsorption properties of mesoporous manganese oxide

The effects of Fe-doping on MnO2: phase transitions, defect structures and its influence on electrical properties

“…In order to enhance the properties, up until now, various synthesis methods have been developed, namely sol–gel, 10 co-precipitation, 11 electrodeposition, 12 and hydrothermal reaction. 13 These various methods are able to reduce the crystal size, enlarge the surface area for the enhancement of the ion diffusion rate 8 and finally improve the supercapacitive performance of MnO 2 .…”

Synthesis and colloidal-chemical properties of manganese dioxide hydrosols synthesized in the presence of sodium thiosulfate

“…The method described by A. I. Ivanets [10] was used for the synthesis of manganese dioxide. Synthesis conditions were chosen to obtain systems that maintained aggregate stability for several weeks [13,14].…”

“…Manganese dioxide hydrosol may be obtained by various redox reactions by condensation [5][6][7][8][9]. Based on literature data, potassium permanganate was chosen as a source of manganese [10]. Sodium thiosulfate was used as a reducing agent.…”

Synthesis of a MnO2/multiwalled carbon nanotube nanocomposite and its application as a sorbent for removing Cu2+ ions from aqueous media

“…Ultimately, the obtained suspension was filtered and washed several times with deionized water and ethanol and then dried it at 100 C for 12 hr. [9][10][11][12]…”
