From melamine–resorcinol–formaldehyde to nitrogen-doped carbon xerogels with micro- and meso-pores for lithium batteries

Abstract

Novel multi-scaled porous nitrogen-doped carbon is synthesized by enriching the simple R–F method with: addition of melamine and PEO–PPO–PEO micelles for nitrogen-doping and duct percolation; integration of the CO₂ activation process for the most critical formation of abundant 2 nm pores.
