Low-temperature gas and pressure sensor based on multi-wall carbon nanotubes decorated with Ti nanoparticles

Chemiresistor sensor composed by MWCNTs decorated with Ti nanoparticles presents selectivity to gases at low substrate temperature and pressures. The self-heating effect open the opportunity to perform experiments at locally elevated temperatures using CNT/NP structures, interesting for studies of temperature activated processes such as catalysis and gas sensor devices.
