 Abstract: Efficient methods for the synthesis of carbon nanostructures with high specific surface area and controlled morphologies are crucial for their use in various applications. Here, we report a low-temperature precursor method for the synthesis of nanostructured carbon materials and show how the aggregate morphology and the specific surface area of isolated carbon materials depend on the composition, synthesis conditions and chemical nature of the precursor. Complex zinc compounds (carboxylates, alkoxides), capable of a pseudomorphic transformation into composites of the general composition ZnO:nC during heating in an inert gaseous medium, were used as precursors. The ZnO nanoparticles (10–15 nm) were washed from the composites by diluted formic acid. The obtained carbon materials exhibit different morphologies and specific surface areas up to 1706 m2/g. For two synthesized carbon materials, their sorption properties with respect to nickel(II) ions were studied. It was found that these materials, despite the differences in the morphology and specific surface areas of their particles, have the same sorption capacity with respect to nickel ions. Sorption has a physical nature and is well described by the Langmuir isotherm.
