Using Sargassum as the precursor, a novel approach was developed to synthesize three-dimensional porous carbons as high-performance electrode materials for supercapacitors via KOH activation and subsequent nitrogen-doping employing melamine as...
2D graphitized porous carbons decorated with high contents of nitrogen sites such as pyridinic nitrogen were developed, which were used as efficient and reusable solid base catalysts for transesterification to biodiesel.
Enteromorpha prolifera was converted into hierarchical carbons through the carbonization and activation with surface area and pore volume up to 3345 m2 g−1 and 1.94 cm3 g−1, showing excellent performance for H2 storage and supercapacitors.
Nitrogen-doped, hierarchical porous carbons with a high surface area were simply prepared from gelatin using nano-ZnO as both the template and activating agent.
