Mesoporous SnO2 nanomaterials with the central pore sizes of 4.1 nm, 6.1 nm and 8.0 nm have been fabricated by a novel carbon-assisted synthesis method (CAS). By using this method, the pore size can be easily regulated by adjusting the concentration of glucose in the precursor solution. The prepared SnO2 nanomaterials with distinct pore sizes were characterized by transmission electron microscopy (TEM and HRTEM) and nitrogen adsorption-desorption analysis. Besides, the gas sensing properties of these mesoporous SnO2 nanomaterials were evaluated. Testing results reveal that the three kinds of m...
