Nitrogen-doped porous carbon with well-balanced charge conduction and electrocatalytic activity were synthesized from nitrogen-rich pitch by hard-template method. The sample carbonized at 900 °C possessing high nitrogen content (7.11 wt.%) and large specific surface area exhibits high electrocatalytic activity in dye-sensitized solar cells. A fast charge conduction involving facile ion transport and...
Carbon nanosheets were successfully prepared from easily available and low-cost petroleum asphalt via a facile and recyclable molten-salt method. The as-made carbon nanosheets exhibit excellent performance on energy storage both for lithium-ion batteries (LIBs) and sodium-ion batteries (SIBs): as the anode of LIBs, they provide a high reversible specific capacity (729 mAh g−1 at 100 mA g−1), excellent...
