Abstract
Novel synthetic control for the generation of carbon replicas has been successfully performed to produce either highly ordered networks of carbon nanofibers with uniform mesopores or disordered carbon nanofibers. Both of these materials were templated from SBA-15 silica modified under different conditions. This control was accomplished through different pretreatment methods of the as-synthesized silica host at relative low reaction temperatures. The use of either as-synthesized or HCl/EtOH washed silica hosts resulted in highly ordered carbon networks. On the other hand, this work also represents an efficient synthesis route for loose carbon nanofibers by using a controlled calcination process for SBA-15.
