Nanofibrous Cathode Catalysts with MoC Nanoparticles Embedded in N-Rich Carbon Shells for Low-Overpotential Li-CO Batteries.

Li-CO batteries with high theoretical energy densities are recognized as next-generation energy storage devices for addressing the range anxiety and environmental issues encountered in the field of electric transportation. However, cathode catalysts with unsatisfactory activity toward CO absorption and reduction/evolution reactions hinder the development of Li-CO batteries with desired specific capacities and sufficient cycle numbers. In this work, a multifunctional nanofibrous cathode catalyst that integrates N-rich carbon shells embedded with molybdenum carbide nanoparticles and multiwalled carbon nanotube cores was designed and prepared.

sp. nov., a novel actinobacterium isolated from rhizosphere of .

A Gram-stain-positive, non-motile and short rod-shaped actinobacterium, designated strain LNNU 22110, was isolated from the rhizosphere soil of the halophyte (Bunge) Freitag and Schütze, which collected in Xinjiang, north-west China. Growth occurred at 10-45 °C, pH 6.0-10.
