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/IDâ¯=â¯4.17) and N-doping (5.32%). The reversible capacity of PDC was 1006.4â¯mAh/g at 0.1â¯A/g and 278.2â¯mAh/g at 5.0â¯A/g. Moreover, PDC demonstrated the reversible capacity of 520.8â¯mAh/g after 500 cycles at 1.0â¯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.
