The shape‐controlled star‐like and rod‐like γ‐MnO2 nanocrystals are prepared by vitriolization of synthesized manganese oxides with the adjustment of the molar ratio of Mn precursors in the ammonia solution. The properties of the product, γ‐MnO2, are investigated by scanning electron microscopy, X‐ray powder diffraction, transmission electron microscopy, etc. The prepared rod‐like γ‐MnO2 nanocrystals...
Mesoporous particles and 1D nanorods of cerium oxides have been prepared by modifying the hydrothermal route of a surfactant-assisted controllable synthesis. Mesoporous cerias were obtained in a sealed glass vessel under continuous stirring, while ceria nanorods were obtained in a Teflon-lined autoclave without stirring. The mesoporous cerias did not show long-range mesoscopic organization, exhibiting...
