dc.description.abstractA solvent evaporation induced coassembly approach combined with a comburent CaO2-assisted calcination strategy was employed for the synthesis of ordered mesoporous indium oxides by using lab-made high-molcular weight amphiphilic diblock copolymer poly(ethylene oxide)-b-polystyrene (PEO-b-PS) as a template, indium chloride as an indium source, and THF/ethanol as the solvent. The obtained mesoporous indium oxide materials exhibit a large pore size of ∼14.5 nm, a surface area of 48 m2 g-1, and a highly crystalline In2O3 nanosheets framework, which can facilitate the diffusion and transport of gas molecules. By using an integrated microheater as the chemresistance sensing platform, the obtained mesoporous indium oxides were used as sensing materials and showed an excellent performance toward NO2 at a low working temperature (150 °C) due to their high porosity and unique crystalline framework. The limit of detection (LOD) of the microsensor based on mesoporous indium oxides can reach a concentration as low as 50 ppb of NO2. Moreover, the microsensor shows a fast response-recovery dynamics upon contacting NO2 gas and fresh air due to the highly open mesoporous structure and the large mesopores of the crystalline mesoporous In2O3.
