Advancements in nanotechnology have promoted the rapid development of diverse nanosystems for biomedical applications. Manganese dioxide (MnO2) nanomaterials attracted numerous attentions field biosensing and cancer treatment due to their unique properties, such as simple fabrication procedures, broad optical absorption, high oxidation catalytic ability. Especially, intelligent stimuli-responsi...

We present a one-step synthesis process for ultrathin non-crystalline MnO2 nanosheets. Their thickness is about 2 nm and the width varies from 5 to 20 nm. They induce a higher capacitance than zero-dimensional spheres or one-dimensional rods. When heat treated at elevated temperature MnO2 nanosheets partly grow into crystalline Mn2O3 rods.

Nanostructured Mn oxide clusters supported on mesoporous silica KIT-6 efficiently evolve O(2) in aqueous solution under mild conditions.
