We demonstrate a low-cost and facile strategy to synthesize mixed-valent MnOxspheres constructed from nanocrystals (~5 nm), containing MnII, MnIII, and MnIVspecies. Such highly active mixed-valent MnOxspheres with high surface area greatly improve the performance of Li–O2batteries.

High Surface Area Materials

Cr ion-polluted industrial water was treated with commercial activated carbon and with either mercaptane- and amine-functionallized silica nanoparticles, revealing that the use of relatively low surface area materials can advantageously compete with high surface area materials, traditionally utilized for removing hazardous metal ions, provided a proper surface functionalization of the nanoparticles is in place. FTIR and SEM characterization of the different materials and stages of the experiments are provided, as well.
