One-step synthesis of highly porous carbon graphite/carbon nanotubes composite by in-situ growth of carbon nanotubes for the removal of humic acid and copper (II) from wastewater

摘要

Porous carbon graphite/carbon nanotubes composite was prepared in a one-step process. Carbon nanotubes (CNTs) were grown in-situ simultaneously with the formation of the porous carbon material. Two plastic pastes, with and without ferrocene as catalyst for CNTs growth were prepared by mixing at room temperature a thermosetting phenolic resin, a graphite powder and cellulose derivatives. Both pastes were shaped and carbonized at 800 degrees C under N-2. The porosity of materials was correlated to the weight losses induced by the cellulose derivatives decomposition and phenolic resin carbonization.
