In this work, we report a series of defective carbon catalysts prepared through a facile and scalable “N-doping-removal” process using seaweed biomass sodium alginate (SA) as precursor. Our systematic studies reveal that the defect content, porosity characteristic and conductivity of defective carbons can be finely tuned by manipulating the pyrolysis temperature and viscosity of precursor polymer...
Phosphorus-doped nanomesh graphene (PG) with huge specific surface area and lamellar hexagonal structure has been synthesized by a thermal annealing method using MgO as a template and triphenylphosphine (TPP) as both phosphorus and carbon source. The synthesized PG with a high phosphorous content of 1.61 at% is found to exhibit efficient metal-free heterogeneous catalytic activity for aerobic oxidative...
A series of nitrogen enriched microporous carbons were facilely prepared by KOH activation using melamine-doped phenolic resins as precursors. The activated carbons show high CO2 uptakes up to ca. 1.3mmolg−1 under low pressure (0.15bar, 25°C), which can be ascribed to not only their optimal fraction of ultramicropores but also the high N-contents. One of the samples even exhibits excellent adsorption...
