Resumo
Several types of carbon nanostructures
(amorphous and graphitic), for the coating of SnO2
nanobelts and nanoparticles were obtained by a single
catalytic process, during methane, natural gas, and
methanol decomposition using the reactivity of
surface-modified SnO2 nanostructure as a nanotemplate.
The nanostructured catalyst templates were
based on transition metal nanoparticles supported on
SnO2 nanobelts previously prepared by a carbothermal
reduction process. Carbon-coated SnO2
nanopowders were also successfully synthesized for
the fabrication of carbon spheres. The carbon coating
process and yield, along with the nature of the
nanostructured carbon, are strongly influenced by the
chemically modified surface of the SnO2 nanostructure
template and the chemical reaction gas
composition. The preliminary catalytic activity and
gas-sensing properties of these novel materials based
on metal nanoparticles and carbon-coated SnO2 were
determined.
