Mesoporous hematite nanoparticles (HNPs) encapsulated SiO2 -TiO2 nanocomposites (STNC) are synthesized and heat-treated at low-temperature 50 degrees C for 1 h (STNC/1h) and 2h (STNC/2h) by sol-gel process for hydrocarbons chemical sensing. Microscopic analysis revealed the thermally stable hierarch...
