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