| 英文摘要 | a facile and cost-efficient hydrothermal and lyophilization two-step strategy has been developed to prepare three-dimensional (3d) sno2/rgo composites as no2 gas sensor. in the present study, two different metal salt precursors (sn2+ and sn4+) were used to prepare the 3d porous composites. it was found that the products prepared from different tin salts exhibited different sensing performance for no2 detection. the scanning electron microscopy and transmission electron microscopy characterizations clearly show the macroporous 3d hybrids, nanoporous structure of reduce graphene oxide (rgo), and the supported sno2 nanocrystals with an average size of 2-7 nm. the specific surface area and porosity properties of the 3d mesoporous composites were analyzed by braunauer-emmett-teller method. the results showed that the sno2/rgo composite synthesized from sn4+ precursor (sno2/rgo-4) has large surface area (441.9 m(2)/g), which is beneficial for its application as a gas sensing material. the gas sensing platform fabricated from the sno2/rgo-4 composite exhibited a good linearity for no2 detection, and the limit of detection was calculated to be as low as about 2 ppm at low temperature. the present work demonstrates that the 3d mesoporous sno2/rgo composites with extremely large surface area and stable nanostructure are excellent candidate materials for gas sensing. |
