Nitrogen-doped mesoporous carbon (NMC) has been synthesized by sol–gel process using a mixture of phenol and formaldehyde as source of carbon, and melamine as source of nitrogen. The Ludox-AS40 (40wt% SiO2) is employed, for the first time, as hard template to obtain polymeric gel by prolonged heat treatment at 80°C. The wt% of nitrogen is tuned by varying the weight ratio of melamine to phenol. Stable...
