Hierarchically porous carbon (HPC) materials with rich oxygen-containing groups at the surface were prepared by a facile one-pot approach using wild jujube pit (WJP) as the biomass precursor. Effect of annealing temperature on the texture and electrochemical properties of the obtained HPC materials was investigated. After the WJP is annealed at 800°C, the resulting HPC sample (WJC-800) contains 6...
In order to enhance electronic/ionic conductivity and stabilize the crystal structure of the layered V2O5 material, carbon-encapsulated Mn-doped V2O5nanorods (Mn0.1V2O5@C) were prepared through hydrothermal treatment and followed by annealing at a high temperature. The as-prepared sample appears as quasi spheres with a diameter range of 2–5μm, in which the Mn0.1V2O5 nanorods (20nm in diameter and...
