Letter

A new approach for synthesis of nanoporous carbon is reported. This involves: (1) synthesis of the template of iron nanoparticles in situ with formation of carbon by chemical vapor decomposition of iron pentacarbonyl and ethanol, and (2) removal of the template by acid treatment. The present template approach is much simpler than previous ones involving separate procedures for preparation of template materials and graphitization and suitable for large-scale production.

A number of methods for the preparation of nanoporous carbon have been developed, with the traditional one being the carbonization–activation route used to produce activated carbon [1, 2]. However, since the carbon precursors were generally in solid state, the controllability of the pore size distribution of the porous carbon was limited [3]. The synthesis of the template is a separate step from the formation of carbon, and filling the template is always a sophisticated process. Additionally, the high chemical stability...
