Abstract
Hierarchical porous carbon was synthesized from porphyra using nickel nanoparticles as the template for mesopore formation and as a catalyst for carbon graphitization. The porphyra-derived carbon (PDC) showed a high degree of graphitization (IG/ID = 4.17) and N-doping (5.32%). The reversible capacity of PDC was 1006.4 mAh/g at 0.1 A/g and 278.2 mAh/g at 5.0 A/g. Moreover, PDC demonstrated the reversible capacity of 520.8 mAh/g after 500 cycles at 1.0 A/g with 92.3% capacity retention rate. The PDC can be served as an advanced anode material for high-energy rechargeable lithium-ion batteries.
