Wastewater treatment is indispensable as wastewater can lead to adverse health effects and deteriorate the quality of life on earth. Photocatalysis a facile methodology address this issue. In study, nanocomposites (NCs) manganese oxide (Mn3O4) nickel (NiO) were synthesized in different weight ratios via solid-state reaction route. Structural properties, optical surface morphology, functional gr...

Water-soluble organic pollutants, such as phenolic compounds, have been exposed to environments globally. They a significant impact on groundwater and surface water quality. In this work, different Mn3O4 catalysts were prepared for metal oxide activation of peroxymonosulfate (PMS) remove the compound from environment. The as-prepared characterized using thermogravimetric-differential thermal an...

We, for the first time, report that many Mn oxides (Mn3O4, α-Mn2O3, β-MnO2, CaMnO3, Ca2Mn3O8, CaMn3O6 and CaMn4O8) in the presence of cerium(IV) ammonium nitrate, in the water oxidation, convert to layered Mn oxide. This layered Mn oxide is an efficient water oxidizing catalyst.

Three-dimensional self-supported cathode nanoarchitectures are the key to develop high-performance thin film lithium-ion microbatteries and flexible lithium-ion batteries. In this work, we have developed a facile “hydrothermal lithiation” strategy to prepare vertically aligned porous LiMn2O4 nanowall arrays, comprising highly crystallized spinel nanoparticles, on various conductive substrates w...

Advances in aqueous potassium-ion batteries (APIBs) are hindered by the lack of cathode materials with fast K+ transport kinetics and stable structure during intercalation/deintercalation. Herein, a birnessite/spinel Mn3O4 heterostructure...

A facile, solution-phase route to mass fabrication of one-dimensional single crystalline Mn(3)O(4) nanowires with a unique core/sheath heteronanostructure, controlled aspect ratios, and narrow diameter distribution was reported. The single crystalline Mn(3)O(4) nanowires have considerably large coercivities (H(C) > 1 T) at low temperatures.
