Catalyst free silica templated porous carbon nanoparticles from bio-waste materials

Porous Carbon Nanoparticles (PCNs) with well-developed microporosity were obtained from bio-waste oil palm leaves (OPL) using single step pyrolysis in nitrogen atmosphere at 500-600 °C in tube-furnace without any catalysis support. The key approach was using silica (SiO 2 ) bodies of OPL as a template in the synthesis of microporous carbon nanoparticles with very small particle sizes of 35-85 nm and pore sizes between 1.9-2 nm. This work described a simple method to produce the bulk porous carbon nanoparticles from bio-waste materials without any catalyst support.
